Description
"decibel x PRO" is one of very few sound meter apps on the market that has highly reliable, pre-calibrated measurements and supports frequency weightings: ITU-R 468, A and C. It turns your iOS device into a professional noise meter, precisely measures the sound pressure level (SPL) all around you. This extremely useful and beautiful tool will not only be a great tool for many uses but also bring you a lot of fun. Have you wondered how quiet is your room or how loud is a rock concert or sport event? "decibel x PRO" will help you answer all of those. WHAT MAKE IT GREAT AND STAND OUT FROM OTHER APPS: - Trusted accuracy: the app is tested and pre calibrated for all Apple devices. The precision is matching with real SPL devices - Apple Watch support: see noise level right from your wrist - Frequency weighting filters: ITU-R 468, A, B, C, Z - Powerful, smart history data management: + Recording data can be saved into a list of history records for future access and analysis + Each record can be exported as hi-res PNG graph or CSV text via sharing services + iCloud support which synchronize all history records across your Apple devices + Fullscreen mode to give overview the whole history of an record - Dosimeter with NIOSH, OSHA standards - FFT and BAR graphs to display real time FFT. Those are very useful for frequency analysis and musical tests. Real time predominant frequency is also displayed. - WAVE graph with 2 display modes: Rolling & Buffer - InstaDecibel to capture your dB report overlaid on photos and easily shared via popular social networks (Facebook, Instagram, Messages, etc.). - Support both Portrait and Landscape layouts - Beautiful, intuitive and carefully crafted UI design - Optimized for iOS 11 OTHER GREAT FEATURES: - Standard time weightings (Response Time): SLOW (500 milliseconds) and FAST (200 milliseconds) - Trimming calibration from -15 dB to 15 dB - Standard measurement range from 30 dBA up to 130 dBA - HISTO graph for plotted history of the recorded values - Real time scale level chart - Display Current, Average/Leq, and Max values with both nice and clear digital and analog layouts - Quick reference text to help you compare with real-life examples - "Keep Device Stay Awake" option for long duration recording - Reset and clear current recording at any time - Tap on Max value to reset at any time - Pause/Resume the tool at any time NOTES: - Please do not expect a quiet room reading will be 0 dBA. The range 30-130 dBA is the standard usable range and an average quiet room will be about 30 dBA. - Although all devices are pre-calibrated, custom calibration is suggested for serious purposes requiring higher precision and accuracy. You will need a real external device or calibrated sound meter as a reference, then adjust the trimming calibration until the reading matches with the reference. If you like it or have suggestions, please support us by rating and giving us comments and feedback.
Great app
by Duke5507 on 2019/11/17 15:00
Takes people’s opinions out of the discussion. And there is always a discussion
Simple function - amazing app!
by Gene-Photo-Audio on 2019/11/15 20:37
For something as simple as showing current dB level this app does an amazing job of showing a great UI with tons of options and features on how to use and display the data. Best dB app out!
One missing thing
by Love and frustration on 2019/11/09 22:59
landscape view would be appreciated.

by avastudioshd on 2019/11/04 02:48
This is a very useful app, especially when checking audio in church, my home studio,etc. Thanks
New features are great
by Charlie19Clay on 2019/11/03 23:35
The new features are all good, some are just fun, and some helpful. I have regular access to two pro decibel meters (both B&K with recent calibrations) and this app consistently shows very similar results with just a small calibration, which can be made very easily within the app (I add 1.3 decibels) I consider it accurate and would rely on the results if need be.
Terrific for Home Theatre
by Dozer B on 2019/11/01 22:19
Hello just wanted to say how pleased I am with the Pro version as it’s used in my Theatre to Calibrate Speaker Levels. Been using for well over one year and have it on all Five Apple Devices. I had this app tested with real professional sound microphone and calibrated to within 2dB. If you know what your doing you can use the Freq Analyzer to EQ your home theatre Subwoofers. Thanks for the great app!!! Jason B. PADUCAH.
Excellent app
by JudoBear on 2019/10/13 18:42
Excellent app for measuring sound noise quickly
Keeps Asking Permission
by infohou on 2019/10/10 23:41
I have to keep clicking OK when try to reset the dB peak. There should be a setting that says don’t ask.
One of the best apps on IOS
by Jeffk332 on 2019/10/06 21:01
This app does what it says it does. The UI design is outstanding and the logging works without a flaw. I took an 8 hour measurement and the app worked perfectly. YouTube reviews show that this app is within 1 dB accurate. That makes it the best sound measurement tool in existence because of the UI and features possible due to it running on an iPhone.
Great App
by AVG99 on 2019/09/29 12:28
I have always had a sound meter usually it was a old clunky one from radioshack with this app I had a modern way to check sound levels. Good app, good update.
Newest version
by rbe7561 on 2019/09/22 21:23
I have used the app for quite awhile but the newest version that I just installed on my new iPhone 11 has a 15-20 second delay for the sounds to be registered on the meter and graph. I was hopeful that a setting would correct this but so far nothing corrects that. I hope that the developer is aware of this and can correct it in the next release.
Video bugs
by Bekuz_Ikan on 2019/08/29 14:55
I see video ability is still really buggy, and it still won’t take landscape full screen videos with DB overlaid. Hopefully that can get resolved. I’m surprised more people aren’t needing or see the need to take a video of what is making the sound.
Such a Great App!!
by LSMD on 2019/08/29 01:39
This app does what I needed it to do, and loads more, and it looks FANTASTIC while doing it. You will not be disappointed.
Back to the drawing board
by Copier guy 123 on 2019/08/28 21:43
Ok 8.00 is here. Yes I use this professionally (not exclusively). Ok so using pro I already had no ads. You have frequencies across the top but then you plop dumb test right over them like “quiet home”. All new dosimeter!!! Except it used to work fine and now doesn’t work at all. All attempts to switch to dosimeter get no reaction. Thanks for screwing up what was the best sound meter on the market. IPhone 8.
Poor stability
by sorkp68 on 2019/08/22 02:33
I have the pro, app works intermittently on WiFi, does not work on cellular (iPhone). Requested support 3 times over last 6 weeks but no reply.
Awesome!
by Ear Cleaner on 2019/08/17 18:45
Elegant, everything a professional needs, as well as anyone interested in how sound looks and feels...a must in this day and age of sound pollution!
I already paid for upgrade!
by Pond draggee on 2019/08/11 23:55
I have paid for the upgrade and everytime I open this app it is like I have not. I have asked for support and no response.
Doesn’t work
by Guitars77 on 2019/08/05 00:05
The app doesn’t work. It can’t access the internal mic on the phone (and yes. I know how to give permission).
Get NIOSHA instead
by /:;))32)77 on 2019/08/02 22:47
DB pro is not worth the eight dollar fee. A simple an accurate decibel meter can be found at NIOSHA
THE best app
by John11: on 2019/07/27 02:29
I’ve tried 4 other meter apps. None compare. How much is your hearing worth?! Let me rephrase... is the price of this app too much $ for a lifetime of hearing damage?!!! So many tools to choose from... camera, meters, guides. All on this app. Easy to use... Nice job developers!
iphone 6 plus photo crash
by BroDoo on 2019/07/18 02:15
Every time i switch from main screen to Photo screen (within app) the app shuts down. rebooted phone - reinstalled app - will not work anymore - at 1st it worked a few times - but then crashed - thats the only reason i got the app - to document the noise.
It keeps aborting
by MarieAnnet on 2019/07/16 12:42
I bought the Pro because I wanted to record a few “background” sounds that — with my new hearing aids — sound so much louder (coffee maker, a/c, fans, water, etc. I’m returning soon to get so my hearing aids adjusted and thought these recordings would help. But after saving a recording, the program aborted. And aborted. And aborted. Every time I went back in, it just ended. I was finally able to get it to stay open to record once again, but after each recording it would abort again it was a minute or more before it would stay open. I’m not impressed. But I’d like to be.
Best SPL App I’ve Used
by B.J.S. on 2019/07/07 21:50
This is the best SPL meter app I’ve used. Well worth the purchase. The only suggestion I have is that it doesn’t rotate 180 degrees on the iPhone XS Max like it did on my old iPhone 6. I like to have the microphone at the bottom of the phone pointed at the speakers so to have the UI flip upside down was very useful. Also the “email support” button in settings didn’t work when I pressed it. Hence my notes here. Otherwise it’s great and I use it in the theater everyday when setting up for a screening.
App does not work
by Gonagain on 2019/06/26 22:16
Payed for the pro upgrade. App shuts down does not work tried to get support no response do not wast your money
Sound
by sal1503 on 2019/06/12 12:13
Great app very helpful for our business which is the trade shows
Number one app
by weeze 63 on 2019/06/07 06:51
I install sound systems in Harley’s and have been using this app for a year or so. I calibrated it with a local bands measuring meter and was surprised it needed very minor adjustments. And no problem with ADDS. Also don’t know if it matters but I am using a iPhone 7 No BS it works great
Better than ever
by CA-KS-RN on 2019/05/29 05:08
I’m just a hobbyist, so I don’t need extreme accuracy. That said, previous apps I’d tried didn’t seem accurate, and compared to a handheld (actual) sound meter, usually weren’t. When I found the non-Pro app, it seemed spot on, and while the ads were ever present, they weren’t annoying (unlike another app that lets you use the trial version for 2 minutes and then stops working and puts up a “buy me” screen with an almost invisible close button). But after using the “free” version for a while, I decided this was worth it. I’ve been enjoying the new features such as the frequency charting feature. Pretty cool seeing what frequency the drum beat is, or why band X seems so much louder despite being a lower decibel reading (more sound closer to 1500 Hz vs 300 Hz).
Thanks for bug fixes
by DaBigBadOtis on 2019/05/28 23:44
Updating review after bug fixes
Fun and good
by Waitcho on 2019/05/27 15:00
I have advanced ear training and worked in studios for a few years. I am by no means an expert but I’m more than an enthusiastic hobbyist. THAT SAID. Love this app. Helps w my new party trick called How Many DBs Are We At Right Now. I don’t go to a lot of parties. Great app.
Fantastic app; Analyst friendly
by earpro 100101 on 2019/05/23 14:27
This is a fantastic app! For someone who works in OSHA hearing conservation the ability to take a photo with the metadata alone is worth the price. Being able export the data to a table is great! The only recommendation I can give would be to include, in the setting, options to customize the metadata for your csv export and camera, specifically, a time stamp (DTG) and frequency, and location that way we can isolate harmful frequencies and conduct a more thorough analysis.
Waste of money
by IranIran on 2019/05/14 05:30
This super overpriced app is missing lots of basic features and doesn’t record correctly. Even with sleep mode record option on, it stops recording when the device sleeps. I want my money back!
Shuts music off when streaming Bluetooth
by LowToneNashville on 2019/05/02 00:30
Defeats the purpose of the app for a lot of users. Please fix.
Musician tool
by Dp373 on 2019/04/22 18:19
Great for monitoring Spl exposure.
Video lacking
by Shap08 on 2019/04/22 16:33
This seems like it could be a really good app. The problem I have is I cannot turn the phone upside down (mic is at the bottom) to take video while holding the phone upside down to avoid hands being near the mic. Also can’t turn it sideways. Some bugs on the video function cause crash as well. Hopefully they add this functionality.
Fixed
by LED4GOD on 2019/04/16 18:21
Bug was fixed that was causing it to crash. Works well.
Update: Opens now (re: Can’t get it to open)
by strobeman4x4 on 2019/04/15 16:18
One more update: Developer just reached out to me to tell me the crash problem is fixed! Changing to five stars! Absolutely awesome customer service! **older review** Below is my old review. I couldn’t get it to open anymore. So I deleted the app and re-downloaded and now it opens. I’m loving the app. Hoping it doesn’t start crashing again **oldest review** iOS v12.1.2 So far I can’t get this to open. It crashes before it opens. I hope I can edit the review once this is fixed.
Love It
by CraigInCO on 2019/04/14 00:06
It’s does what I need again! Thank you to the developers for making it great again! And for letting me know all is good now!
Just downloaded this app
by therev49 on 2019/04/09 20:31
I just downloaded this app and it closes as soon as it starts up. I have an iPhone XS Max, 256 gb storage running iOS 12.2, apple’s latest version. Fix this app or refund the purchase price ASAP. Despite what the developer says or claims, this app was not corrected or fixed as it disappears as soon as the app comes up but stays in the background. When you flick the bottom of the phone screen you can see it but as soon as you lift your finger off the screen it disappears again. What a frustrating piece of crap this app is. If my credit card gets charged for it I will take it up with my card issuer so the charge is removed from account. Should that fail I will file a complaint with the NYS attorney general office as well as the FTC. Yes I am that po’d by this app. This is the first one that I bought where this happened.
Crashes
by CMAWYO on 2019/04/06 15:26
Worked fine when downloaded, then the next day-crashes, open app and it immediately closes. :-(
How accurate is the app?
by Dbeipi on 2019/04/01 21:24
You claim the app is precalibrated for all Apple devices and precision matches “real SPL devices”. What is the accuracy tolerance and compared to what standard? Your statement is meaningless without data. I really like the app, but I must treat the results as estimates of unknown precision.
Auto starts after reset data!
by rockku1234 on 2019/03/19 15:02
When data is reset the meter starts automatically! There is no setting to turn this off. Resulting in inaccurate results due to capturing ambient noise
Frequent Crashes
by Keith80 on 2019/03/14 20:58
Spent around $8 for the pro version, and it crashes all the time.
Great
by Scogmo on 2019/03/09 21:49
My slow WiFi up in the woods didn’t download all the features on iPad at first, weird. When I drove to town my iPhone got the recording data features and when I got home they were on the iPad too. So ignore my 4 star review wishing they had more features. :-)
Won’t work.
by 1234567890"@&$)( on 2019/02/27 02:26
Application constantly shuts itself off. Very disappointed.
The delete function for a single report does not work
by mira100000 on 2019/02/12 03:51
It was a good app until the function of seeing the report horizontally was removed. In addition, when you delete one report then close the app, that report comes back.
Real volume feedback
by Scottkins81 on 2019/02/01 17:07
This app allows me to give real time feedback to my students on their volume level during a performance. I like that I can take a photo and attach it to their assignment as proof.
Camera mode crashes the app... FYI
by MusicalMyers on 2019/01/24 23:24
I’m a music and Theatre teacher, and just attended a conference, one session was on the need for hearing protection for music teachers. I panicked, bought some cheaper earplugs for the time being, set an audiology appointment, and purchased this app. I’ve only played with the app, for a few minutes and noticed that on the camera setting the app crashes. Seems like the developer is very responsive though, and is why I went through purchasing the app. Fyi: I’ve played on my piano for just a few minutes and was shocked that I can easily push my piano about 95 decibels! Yikes! Guess, I’m glad I purchased the ear plugs... and the app.
New update = Fixed
by Crazyguy™ on 2019/01/24 18:09
Developers seem to care and fix issues quickly
Modern Dark theme crashes App
by Philip Levin on 2019/01/22 07:43
For those wondering, if you had the modern dark theme enabled, your app will crash. A temporary fix to this would be to redownload the app and leave the classic theme on. Until the developer comes to fix this, we will be stuck with this for now.
Dissatisfy
by Jrwyjr on 2019/01/18 19:07
App stopped working! Don’t waste your money.
New Update Crashes
by Jaybird302 on 2019/01/17 17:46
I really enjoyed using this app for many different uses. However, since the last update it crashes as soon as it starts up. I’m about to bail and find another app. No response from developer when contacted either. Pretty salty about spending money on this, only to have it be a waste. Running on latest IOS on 8+.
Great but crashes
by The Gerharts on 2019/01/17 17:41
I have an iPhone 7 Plus with latest iOS and this sometimes crashes every time I try to open it. If I delete and reinstall it, it works again for a while. One thing it seems is if I change the theme it will crash right away and I have to reinstall again. Otherwise it’s a great app and I use it at work which is occupational health.
Apple mics are too weak for this app to be useful
by MusicianInVegas on 2019/01/17 07:52
Compared to purpose built spectrum analyzers this app falls off considerably from the mids on up. The response time for the spectrum is also way too slow for the kind of money their asking. Spector is on Android gives a faster, more realistic response. Nice app, just a bit disappointing.
To those having trouble -
by AsaBcOvin on 2019/01/15 11:38
Uninstall and reinstall gets it working again!
Why is app crashing on start?
by viper joe on 2019/01/15 05:53
As I’ve seen one other review with the latest upgrade since December 2018 the app is now crashing at start up. I have tried many times like five or 6+ times and it does not start. I am using a iPhone 6S with latest IOS version. I have reported it with an email and have yet to hear a response. The other reviewer states should we just burn this bridge or is the developer you send an update to fix this. I hope the developer wakes up and resolves this. Anyone else have these issues please notify developer. Other than that I would like to write this is a five star app!!! Has been a great app for a couple of years.
App will not even open
by Jaytron7 on 2019/01/15 03:01
I just upgraded to the paid version and the app will not even open. The screen flashed and goes back to the apple home screen. Completely useless.
Stopped working
by audioengineerx on 2019/01/13 17:56
I used this app a lot, but it has stopped working since the update. I contacted the developer 2 weeks ago but still have not heard back from them
Doesn’t work. Won’t open!
by Gattman#1 on 2019/01/12 10:17
After paying $6 for the pro version of the app, it opened once... then never opened again! A waste of money!
Almost 5 stars — every now and then a crash
by iwoolman too on 2019/01/11 20:32
This one helps me protect my nerve-damaged hearing. If it weren’t for the occasional crash, I would give it five stars. My other nit-pick applies to this and other decibel apps: they all report marginally to significantly different levels in the same environments. I’d love to know which is most accurate. Decibel X Pro, though, is easily my favorite. I like the interface, the ability to record, and the quick and easy-to-read comparisons to noise levels in various environments.

Neat app / needs bugs fixed
by Floorlint on 2018/12/29 00:15
With IPhone: App crashes when you try and change view from classic or try to use camera. I’ve had to several times uninstall and re-install. There were lots of free ones, but chose this assuming things would stay up to snuff for a paid APP. Fingers crossed, We’ll see.
Won’t work since the update.

Frustrating since I used it to maintain acceptable dB level at church
Next to my D👀k and my Brain, my Ears are my Favourite Organ.
by Debauchee on 2018/12/25 05:54
03NOV2018, I went to a Nine Inch Nails Concert in San Francisco, CA. The warm up act was playing so loud that it showed 122db Z Weighted!!! That is INSTANT Hearing Loss!!!👂 wearing my Ear Plugs under my shooting muffs, that only dropped the sound level 6db or to 117db Z Weighted or Permanent Hearing 👂 after 20 seconds. I ran outside and during the break, confronted the sound crew, showing them the data and demanding the lower the volume else I’ll call OSHA and shut down the tour!!! The dropped it to 105db because of your program!!! Later that week, I got a room upgrade due to noisy neighbours and I got a seat 💺 upgrade because the engines were too loud. I am PROUD to be a HEALTH-NAZI (for fun and profit) and you can be TOO!!!

New update crashes when opened
by mtnsoar on 2018/12/25 01:46
I just updated to the newest version of Decibel X Pro, and now it won’t open on my phone. Needed it to measure sound levels at a performance tonight and it wouldn’t open. Very disappointing. I’d rate it “0” stars for that malfunction, but zero isn’t an option. The app has worked well prior to this update.

Decibel X Pro review
by DT-48 fan on 2018/12/19 17:58
Meets all the expectations I had after upgrading from the free version. Sure, more accurate equipment exists and the version may not use beam-forming mics available on the newer iPad Pro, but a. this is adequate to many tasks b. it records & the record can be emailed from the app c. it runs n a pice of equipment you probably always carry d. the cost—the cost—the cost cannot be beat.

Great app for accurate information

When I try to contact app support I get this. “ This Account has been suspended” How Nice.
Works well, convenient, accurate
by Dublinbiker on 2018/12/12 03:53
Very convenient, easy to use, tested its accuracy against machinery I have with factory tested dB levels and is very close. Can’t beat this for $5.
Broken with iOS 12
by xyper on 2018/12/01 00:33
The UI is unusable with iPhone XS and iOS 12: all controls are gone, the only thing visible is a bit of the graphs. Wrote an email to developer, no acknowledgment so far. Was great till iOS 12. Revised: the app now works with XS. So five stars again.
Basic
by bored again bored on 2018/11/27 03:05
Works yet is way too basic for $5.
Crashes
by 458079 on 2018/11/05 03:22
Crashes way too often. Paid 4.99 for the pro hoping that would resolve the issue but it didn’t.
Excellent
by AnotherGolux on 2018/10/17 07:15
I’m very pleased with this app. I have one small suggestion: I would like to see the app start in Pause mode instead of Record, or perhaps offer this as an option. Thanks!
Worth it! Good App!
by Pizza is my favorite on 2018/10/12 23:11
Don't have much experience with this but the app does what we need it to & does it well to check volume inside our haunted attractions.
Works and Looks Great on iPhone XS Max
by Moleman55 on 2018/10/12 15:27
Time to change my rating: The latest update fixed the App and it’s now working as it used to on the iPhone XS Max and iOS 12.0.1. Great App! Old Review: Decibel X Pro does not display properly or work on iOS 12 on the iPhone XS Max. Hopefully, an update is not too far off! My rating will change if or when corrected.
Now fixed on iOS 12 & iPhone Xs!
by Ted Jerome on 2018/10/12 10:12
[Update: latest version now works as expected—thanks!] Opens to the graph completely full screen with no controls. Labels much too small to be read. Request for help from developer unanswered. In other words, a total waste of money. Caveat emptor.
Meter option not presented
by rob in raleigh on 2018/10/10 00:05
I have tried to install this app several times on my iPhone X’s and all I am presented are the 4 histogram views. I do not see the meter presentation as shown in the examples. Looks like a great app if I could see the meter option and other documentation which is supposed to be part of the application
App UI does not display
by NM00001 on 2018/10/08 19:19
Purchased on an iPhone XS Max. The UI from the example images does not display. App frequently crashes. It does show a decibel readout but the font is tiny and difficult to read, and functionality is very limited. I have emailed support twice since last week with no response. Very disappointed and do not recommend.

Decibel X in pro setup
by Skip Powerd on 2018/10/03 18:45
Just got this to use in a 400-seat auditorium new PA system setup. Very useful! I’m doing relative measurements, but it seems to be quite accurate.
Great app

Does the job
Off by 20db
by pengrus on 2018/09/27 05:46
I am shocked to see that it is off by 20db when compared with an external professional noise measuring device. It's calibration trim only allows 15 db adjustment.
Not optimized for iPhone XS Max
by Josh Seahawk on 2018/09/26 00:49
I purchased this app with the hopes of calibrating my speakers but the app doesn't display right on my iPhone XS Max. The screen is cut off and I can't access some of the functions.
Latest iPhone Version
by bill_mann on 2018/08/27 11:55
I’ve been using this app for a few years and it’s never let me down ... until now. The app is useless on my iPhone X now. Since the latest update, the app crashes upon launch. If I repeatedly relaunch the app I may get lucky after 5 or 6 attempts to launch. Yet after it finally opens its unstable if I switch to a different app and usually crashes as well. Contacted support, 2 weeks ago and there has been no response. Hope someone is reading these reviews because I’d really like to know if I should burn this bridge and find another solution.
Crashes
by drbugs10 on 2018/08/21 08:41
Enough said. Upgraded to pro in hopes that crashes would be fixed but no luck. Used to be a great app
Easy to use

Helpful for people with hearing aids
Unstable App
by Captain Earl on 2018/08/12 14:50
This App is unstable. It runs after reboot in iPad and iPhone but crashes on restart AND that is the paid version. Mark me very unhappy to have wasted the money. I am deleting the App.
No microphone
by mycapsir on 2018/08/09 01:20
Does not have button to access microphone.
Good but has a few bugs.
by mr. nemoto on 2018/08/02 21:56
I use this app for training and assessing vocal intensity for Parkinson's patients. There are 3 problems that need to be fixed. One is the data on the summary report doesn't fit on the "page" so the numbers are hard to read. The second problem is that when data is cleared, it immediately starts recording again and the pause button has to be hit quickly. And finally, even the slightest upward swipe (always on accident) flips you into a different screen which is annoying and disruptive.
Needs serious work
by Number1BostonFan on 2018/07/26 15:06
Was at a concert last night and took some pictures showing the measured dB. I was extremely disappointed when I found out the pics weren’t automatically saved to my photos. What’s the point of taking pics if you have to manually choose to save the pics?
Better than ever
by CA-KS-RN on 2019/05/29 05:08
I’m just a hobbyist, so I don’t need extreme accuracy. That said, previous apps I’d tried didn’t seem accurate, and compared to a handheld (actual) sound meter, usually weren’t. When I found the non-Pro app, it seemed spot on, and while the ads were ever present, they weren’t annoying (unlike another app that lets you use the trial version for 2 minutes and then stops working and puts up a “buy me” screen with an almost invisible close button). But after using the “free” version for a while, I decided this was worth it. I’ve been enjoying the new features such as the frequency charting feature. Pretty cool seeing what frequency the drum beat is, or why band X seems so much louder despite being a lower decibel reading (more sound closer to 1500 Hz vs 300 Hz).
Next to my D👀k and my Brain, my Ears are my Favourite Organ.
by Debauchee on 2018/12/25 05:54
03NOV2018, I went to a Nine Inch Nails Concert in San Francisco, CA. The warm up act was playing so loud that it showed 122db Z Weighted!!! That is INSTANT Hearing Loss!!!👂 wearing my Ear Plugs under my shooting muffs, that only dropped the sound level 6db or to 117db Z Weighted or Permanent Hearing 👂 after 20 seconds. I ran outside and during the break, confronted the sound crew, showing them the data and demanding the lower the volume else I’ll call OSHA and shut down the tour!!! The dropped it to 105db because of your program!!! Later that week, I got a room upgrade due to noisy neighbours and I got a seat 💺 upgrade because the engines were too loud. I am PROUD to be a HEALTH-NAZI (for fun and profit) and you can be TOO!!!
Best SPL App I’ve Used
by B.J.S. on 2019/07/07 21:50
This is the best SPL meter app I’ve used. Well worth the purchase. The only suggestion I have is that it doesn’t rotate 180 degrees on the iPhone XS Max like it did on my old iPhone 6. I like to have the microphone at the bottom of the phone pointed at the speakers so to have the UI flip upside down was very useful. Also the “email support” button in settings didn’t work when I pressed it. Hence my notes here. Otherwise it’s great and I use it in the theater everyday when setting up for a screening.
Just downloaded this app
by therev49 on 2019/04/09 20:31
I just downloaded this app and it closes as soon as it starts up. I have an iPhone XS Max, 256 gb storage running iOS 12.2, apple’s latest version. Fix this app or refund the purchase price ASAP. Despite what the developer says or claims, this app was not corrected or fixed as it disappears as soon as the app comes up but stays in the background. When you flick the bottom of the phone screen you can see it but as soon as you lift your finger off the screen it disappears again. What a frustrating piece of crap this app is. If my credit card gets charged for it I will take it up with my card issuer so the charge is removed from account. Should that fail I will file a complaint with the NYS attorney general office as well as the FTC. Yes I am that po’d by this app. This is the first one that I bought where this happened.
Camera mode crashes the app... FYI
by MusicalMyers on 2019/01/24 23:24
I’m a music and Theatre teacher, and just attended a conference, one session was on the need for hearing protection for music teachers. I panicked, bought some cheaper earplugs for the time being, set an audiology appointment, and purchased this app. I’ve only played with the app, for a few minutes and noticed that on the camera setting the app crashes. Seems like the developer is very responsive though, and is why I went through purchasing the app. Fyi: I’ve played on my piano for just a few minutes and was shocked that I can easily push my piano about 95 decibels! Yikes! Guess, I’m glad I purchased the ear plugs... and the app.

Fantastic app; Analyst friendly
by earpro 100101 on 2019/05/23 14:27
This is a fantastic app! For someone who works in OSHA hearing conservation the ability to take a photo with the metadata alone is worth the price. Being able export the data to a table is great! The only recommendation I can give would be to include, in the setting, options to customize the metadata for your csv export and camera, specifically, a time stamp (DTG) and frequency, and location that way we can isolate harmful frequencies and conduct a more thorough analysis.
Almost 5 stars — every now and then a crash
by iwoolman too on 2019/01/11 20:32
This one helps me protect my nerve-damaged hearing. If it weren’t for the occasional crash, I would give it five stars. My other nit-pick applies to this and other decibel apps: they all report marginally to significantly different levels in the same environments. I’d love to know which is most accurate. Decibel X Pro, though, is easily my favorite. I like the interface, the ability to record, and the quick and easy-to-read comparisons to noise levels in various environments.
Great noise monitor
by KeikoTsunami on 2018/04/28 21:55
I occasionally need to monitor noise levels at home or in classrooms when I’m substitute teaching. So I’m a novice at this, although I am a scientist in other areas. This APP does everything I need: records noise levels, lets me adjust the parameters, such maximum acceptable noise level, and I can download the data. It defines & explains everything. It is calibrated. The only thing it has no effect on is my 4 cats’ level of meowing. If only it could feed them.... I’m thrilled with this APP!
New features are great
by Charlie19Clay on 2019/11/03 23:35
The new features are all good, some are just fun, and some helpful. I have regular access to two pro decibel meters (both B&K with recent calibrations) and this app consistently shows very similar results with just a small calibration, which can be made very easily within the app (I add 1.3 decibels) I consider it accurate and would rely on the results if need be.

It keeps aborting
by MarieAnnet on 2019/07/16 12:42
I bought the Pro because I wanted to record a few “background” sounds that — with my new hearing aids — sound so much louder (coffee maker, a/c, fans, water, etc. I’m returning soon to get so my hearing aids adjusted and thought these recordings would help. But after saving a recording, the program aborted. And aborted. And aborted. Every time I went back in, it just ended. I was finally able to get it to stay open to record once again, but after each recording it would abort again it was a minute or more before it would stay open. I’m not impressed. But I’d like to be.
A useful tool
by Radjin on 2018/03/30 13:51
On fast mode it’s pretty good at detecting sounds your ear cannot, leaks in systems, failing bearings. I hope in an update the orientation is enhanced. When I attempt to point the microphone at the source for better location the screen only goes as far as landscape. I would also like to switch between different settings to compare without having to go into a separate settings screen interrupting my work.
Decibel X Pro review
by DT-48 fan on 2018/12/19 17:58
Meets all the expectations I had after upgrading from the free version. Sure, more accurate equipment exists and the version may not use beam-forming mics available on the newer iPad Pro, but a. this is adequate to many tasks b. it records & the record can be emailed from the app c. it runs n a pice of equipment you probably always carry d. the cost—the cost—the cost cannot be beat.
Why is app crashing on start?
by viper joe on 2019/01/15 05:53
As I’ve seen one other review with the latest upgrade since December 2018 the app is now crashing at start up. I have tried many times like five or 6+ times and it does not start. I am using a iPhone 6S with latest IOS version. I have reported it with an email and have yet to hear a response. The other reviewer states should we just burn this bridge or is the developer you send an update to fix this. I hope the developer wakes up and resolves this. Anyone else have these issues please notify developer. Other than that I would like to write this is a five star app!!! Has been a great app for a couple of years.

Works and Looks Great on iPhone XS Max
by Moleman55 on 2018/10/12 15:27
Time to change my rating: The latest update fixed the App and it’s now working as it used to on the iPhone XS Max and iOS 12.0.1. Great App! Old Review: Decibel X Pro does not display properly or work on iOS 12 on the iPhone XS Max. Hopefully, an update is not too far off! My rating will change if or when corrected.
Great but crashes
by The Gerharts on 2019/01/17 17:41
I have an iPhone 7 Plus with latest iOS and this sometimes crashes every time I try to open it. If I delete and reinstall it, it works again for a while. One thing it seems is if I change the theme it will crash right away and I have to reinstall again. Otherwise it’s a great app and I use it at work which is occupational health.
Great
by Scogmo on 2019/03/09 21:49
My slow WiFi up in the woods didn’t download all the features on iPad at first, weird. When I drove to town my iPhone got the recording data features and when I got home they were on the iPad too. So ignore my 4 star review wishing they had more features. :-)
Video lacking
by Shap08 on 2019/04/22 16:33
This seems like it could be a really good app. The problem I have is I cannot turn the phone upside down (mic is at the bottom) to take video while holding the phone upside down to avoid hands being near the mic. Also can’t turn it sideways. Some bugs on the video function cause crash as well. Hopefully they add this functionality.
Number one app
by weeze 63 on 2019/06/07 06:51
I install sound systems in Harley’s and have been using this app for a year or so. I calibrated it with a local bands measuring meter and was surprised it needed very minor adjustments. And no problem with ADDS. Also don’t know if it matters but I am using a iPhone 7 No BS it works great
Newest version
by rbe7561 on 2019/09/22 21:23
I have used the app for quite awhile but the newest version that I just installed on my new iPhone 11 has a 15-20 second delay for the sounds to be registered on the meter and graph. I was hopeful that a setting would correct this but so far nothing corrects that. I hope that the developer is aware of this and can correct it in the next release.
Update: Opens now (re: Can’t get it to open)
by strobeman4x4 on 2019/04/15 16:18
One more update: Developer just reached out to me to tell me the crash problem is fixed! Changing to five stars! Absolutely awesome customer service! **older review** Below is my old review. I couldn’t get it to open anymore. So I deleted the app and re-downloaded and now it opens. I’m loving the app. Hoping it doesn’t start crashing again **oldest review** iOS v12.1.2 So far I can’t get this to open. It crashes before it opens. I hope I can edit the review once this is fixed.
It is simple and works
by Lovejoy Ranch on 2017/11/16 04:18
I got this ap because the screen shot shows sound pressure levels on an octave chart and a historical graph. I wanted to record this spectrum, or at least capture averages for each octave, but it turns out it only plots the average. It does show instantaneous octave bands.
Great tool
by ugly approach on 2017/11/21 23:36
Used this for mixing sound at church. We have some folks who want the sound to be louder due to hearing loss. Used this app (Pro version) to show what the levels are and made everyone happy without touching the mix. Made my life much better!
THE best app
by John11: on 2019/07/27 02:29
I’ve tried 4 other meter apps. None compare. How much is your hearing worth?! Let me rephrase... is the price of this app too much $ for a lifetime of hearing damage?!!! So many tools to choose from... camera, meters, guides. All on this app. Easy to use... Nice job developers!
Great App, when you think things are too loud
by Pgeorge1944 on 2017/11/14 22:12
You are in a Bar or a Pub and you think things are too loud. You can prove it with this App. I have found most Pubs are at 90db or above. I have used it to have the management lower the music sound.
Simple function - amazing app!
by Gene-Photo-Audio on 2019/11/15 20:37
For something as simple as showing current dB level this app does an amazing job of showing a great UI with tons of options and features on how to use and display the data. Best dB app out!
Real volume feedback
by Scottkins81 on 2019/02/01 17:07
This app allows me to give real time feedback to my students on their volume level during a performance. I like that I can take a photo and attach it to their assignment as proof.
Now fixed on iOS 12 & iPhone Xs!
by Ted Jerome on 2018/10/12 10:12
[Update: latest version now works as expected—thanks!] Opens to the graph completely full screen with no controls. Labels much too small to be read. Request for help from developer unanswered. In other words, a total waste of money. Caveat emptor.
Fun and good
by Waitcho on 2019/05/27 15:00
I have advanced ear training and worked in studios for a few years. I am by no means an expert but I’m more than an enthusiastic hobbyist. THAT SAID. Love this app. Helps w my new party trick called How Many DBs Are We At Right Now. I don’t go to a lot of parties. Great app.
Neat app / needs bugs fixed
by Floorlint on 2018/12/29 00:15
With IPhone: App crashes when you try and change view from classic or try to use camera. I’ve had to several times uninstall and re-install. There were lots of free ones, but chose this assuming things would stay up to snuff for a paid APP. Fingers crossed, We’ll see.
Settings crash - fixed
by Colosaldrummer on 2017/09/28 16:26
Update: They have fixed the issue and it works well now. Running 10.3.3 on 6+ and you can't change anything in the settings menu without it crashing to the home screen.
Excellent
by AnotherGolux on 2018/10/17 07:15
I’m very pleased with this app. I have one small suggestion: I would like to see the app start in Pause mode instead of Record, or perhaps offer this as an option. Thanks!
Works as advertised
by Herbstar on 2018/05/20 18:42
Apps should work as intended. The science and tech in this one does. I haven’t had the equipment to test or adjust its accuracy but it appears to be correct out of the box. I recommend it.
Proved my point
by Kerrybatdog on 2018/06/06 03:51
I got this app to measure noise from my upstairs neighbors to prove to management how loud they are. Did exactly what I needed it to do! Now I’m a bit obsessed and often find myself measuring the dB levels around me. Great little app.
Crashes
by 458079 on 2018/11/05 03:22
Crashes way too often. Paid 4.99 for the pro hoping that would resolve the issue but it didn’t.
Great App
by AVG99 on 2019/09/29 12:28
I have always had a sound meter usually it was a old clunky one from radioshack with this app I had a modern way to check sound levels. Good app, good update.
App keeps crashing
by recboxer on 2017/08/18 15:07
I'm running iOS 10.3.3 on an iPhone 6. Whenever I try to modify any of the settings, such as change from the default Z weighting to A weighting, the app crashes.
Back to the drawing board
by Copier guy 123 on 2019/08/28 21:43
Ok 8.00 is here. Yes I use this professionally (not exclusively). Ok so using pro I already had no ads. You have frequencies across the top but then you plop dumb test right over them like “quiet home”. All new dosimeter!!! Except it used to work fine and now doesn’t work at all. All attempts to switch to dosimeter get no reaction. Thanks for screwing up what was the best sound meter on the market. IPhone 8.
New update = Fixed
by Crazyguy™ on 2019/01/24 18:09
Developers seem to care and fix issues quickly
Works well, convenient, accurate
by Dublinbiker on 2018/12/12 03:53
Very convenient, easy to use, tested its accuracy against machinery I have with factory tested dB levels and is very close. Can’t beat this for $5.
Very useful
by patricknss on 2018/06/24 17:32
Great to have in order to understand level of noise environment. Proves a device to evaluate various noise levels of products being considered for purchase
Awesome!
by Ear Cleaner on 2019/08/17 18:45
Elegant, everything a professional needs, as well as anyone interested in how sound looks and feels...a must in this day and age of sound pollution!

New Update Crashes
by Jaybird302 on 2019/01/17 17:46
I really enjoyed using this app for many different uses. However, since the last update it crashes as soon as it starts up. I’m about to bail and find another app. No response from developer when contacted either. Pretty salty about spending money on this, only to have it be a waste. Running on latest IOS on 8+.
Worth it! Good App!
by Pizza is my favorite on 2018/10/12 23:11
Don't have much experience with this but the app does what we need it to & does it well to check volume inside our haunted attractions.
Video bugs
by Bekuz_Ikan on 2019/08/29 14:55
I see video ability is still really buggy, and it still won’t take landscape full screen videos with DB overlaid. Hopefully that can get resolved. I’m surprised more people aren’t needing or see the need to take a video of what is making the sound.
App UI does not display
by NM00001 on 2018/10/08 19:19
Purchased on an iPhone XS Max. The UI from the example images does not display. App frequently crashes. It does show a decibel readout but the font is tiny and difficult to read, and functionality is very limited. I have emailed support twice since last week with no response. Very disappointed and do not recommend.

Description
"decibel x PRO" is one of very few sound meter apps on the market that has highly reliable, pre-calibrated measurements and supports frequency weightings: ITU-R 468, A and C. It turns your iOS device into a professional noise meter, precisely measures the sound pressure level (SPL) all around you. This extremely useful and beautiful tool will not only be a great tool for many uses but also bring you a lot of fun. Have you wondered how quiet is your room or how loud is a rock concert or sport event? "decibel x PRO" will help you answer all of those. WHAT MAKE IT GREAT AND STAND OUT FROM OTHER APPS: - Trusted accuracy: the app is tested and pre calibrated for all Apple devices. The precision is matching with real SPL devices - Apple Watch support: see noise level right from your wrist - Frequency weighting filters: ITU-R 468, A, B, C, Z - Powerful, smart history data management: + Recording data can be saved into a list of history records for future access and analysis + Each record can be exported as hi-res PNG graph or CSV text via sharing services + iCloud support which synchronize all history records across your Apple devices + Fullscreen mode to give overview the whole history of an record - Dosimeter with NIOSH, OSHA standards - FFT and BAR graphs to display real time FFT. Those are very useful for frequency analysis and musical tests. Real time predominant frequency is also displayed. - WAVE graph with 2 display modes: Rolling & Buffer - InstaDecibel to capture your dB report overlaid on photos and easily shared via popular social networks (Facebook, Instagram, Messages, etc.). - Support both Portrait and Landscape layouts - Beautiful, intuitive and carefully crafted UI design - Optimized for iOS 11 OTHER GREAT FEATURES: - Standard time weightings (Response Time): SLOW (500 milliseconds) and FAST (200 milliseconds) - Trimming calibration from -15 dB to 15 dB - Standard measurement range from 30 dBA up to 130 dBA - HISTO graph for plotted history of the recorded values - Real time scale level chart - Display Current, Average/Leq, and Max values with both nice and clear digital and analog layouts - Quick reference text to help you compare with real-life examples - "Keep Device Stay Awake" option for long duration recording - Reset and clear current recording at any time - Tap on Max value to reset at any time - Pause/Resume the tool at any time NOTES: - Please do not expect a quiet room reading will be 0 dBA. The range 30-130 dBA is the standard usable range and an average quiet room will be about 30 dBA. - Although all devices are pre-calibrated, custom calibration is suggested for serious purposes requiring higher precision and accuracy. You will need a real external device or calibrated sound meter as a reference, then adjust the trimming calibration until the reading matches with the reference. If you like it or have suggestions, please support us by rating and giving us comments and feedback.

This is a very useful app, especially when checking audio in church, my home studio,etc. Thanks
New features are great
by Charlie19Clay on 2019/11/03 23:35
The new features are all good, some are just fun, and some helpful. I have regular access to two pro decibel meters (both B&K with recent calibrations) and this app consistently shows very similar results with just a small calibration, which can be made very easily within the app (I add 1.3 decibels) I consider it accurate and would rely on the results if need be.
Terrific for Home Theatre
by Dozer B on 2019/11/01 22:19
Hello just wanted to say how pleased I am with the Pro version as it’s used in my Theatre to Calibrate Speaker Levels. Been using for well over one year and have it on all Five Apple Devices. I had this app tested with real professional sound microphone and calibrated to within 2dB. If you know what your doing you can use the Freq Analyzer to EQ your home theatre Subwoofers. Thanks for the great app!!! Jason B. PADUCAH.
Excellent app

Keeps Asking Permission
by infohou on 2019/10/10 23:41
I have to keep clicking OK when try to reset the dB peak. There should be a setting that says don’t ask.
One of the best apps on IOS
by Jeffk332 on 2019/10/06 21:01
This app does what it says it does. The UI design is outstanding and the logging works without a flaw. I took an 8 hour measurement and the app worked perfectly. YouTube reviews show that this app is within 1 dB accurate. That makes it the best sound measurement tool in existence because of the UI and features possible due to it running on an iPhone.

I see video ability is still really buggy, and it still won’t take landscape full screen videos with DB overlaid. Hopefully that can get resolved. I’m surprised more people aren’t needing or see the need to take a video of what is making the sound.
Such a Great App!!
by LSMD on 2019/08/29 01:39
This app does what I needed it to do, and loads more, and it looks FANTASTIC while doing it. You will not be disappointed.
Back to the drawing board
by Copier guy 123 on 2019/08/28 21:43
Ok 8.00 is here. Yes I use this professionally (not exclusively). Ok so using pro I already had no ads. You have frequencies across the top but then you plop dumb test right over them like “quiet home”. All new dosimeter!!! Except it used to work fine and now doesn’t work at all. All attempts to switch to dosimeter get no reaction. Thanks for screwing up what was the best sound meter on the market. IPhone 8.
Poor stability
by sorkp68 on 2019/08/22 02:33
I have the pro, app works intermittently on WiFi, does not work on cellular (iPhone). Requested support 3 times over last 6 weeks but no reply.
Awesome!
by Ear Cleaner on 2019/08/17 18:45
Elegant, everything a professional needs, as well as anyone interested in how sound looks and feels...a must in this day and age of sound pollution!
I already paid for upgrade!
by Pond draggee on 2019/08/11 23:55
I have paid for the upgrade and everytime I open this app it is like I have not. I have asked for support and no response.
Doesn’t work
by Guitars77 on 2019/08/05 00:05
The app doesn’t work. It can’t access the internal mic on the phone (and yes. I know how to give permission).
Get NIOSHA instead
by /:;))32)77 on 2019/08/02 22:47
DB pro is not worth the eight dollar fee. A simple an accurate decibel meter can be found at NIOSHA
THE best app
by John11: on 2019/07/27 02:29
I’ve tried 4 other meter apps. None compare. How much is your hearing worth?! Let me rephrase... is the price of this app too much $ for a lifetime of hearing damage?!!! So many tools to choose from... camera, meters, guides. All on this app. Easy to use... Nice job developers!
iphone 6 plus photo crash
by BroDoo on 2019/07/18 02:15
Every time i switch from main screen to Photo screen (within app) the app shuts down. rebooted phone - reinstalled app - will not work anymore - at 1st it worked a few times - but then crashed - thats the only reason i got the app - to document the noise.
It keeps aborting
by MarieAnnet on 2019/07/16 12:42
I bought the Pro because I wanted to record a few “background” sounds that — with my new hearing aids — sound so much louder (coffee maker, a/c, fans, water, etc. I’m returning soon to get so my hearing aids adjusted and thought these recordings would help. But after saving a recording, the program aborted. And aborted. And aborted. Every time I went back in, it just ended. I was finally able to get it to stay open to record once again, but after each recording it would abort again it was a minute or more before it would stay open. I’m not impressed. But I’d like to be.
Best SPL App I’ve Used
by B.J.S. on 2019/07/07 21:50
This is the best SPL meter app I’ve used. Well worth the purchase. The only suggestion I have is that it doesn’t rotate 180 degrees on the iPhone XS Max like it did on my old iPhone 6. I like to have the microphone at the bottom of the phone pointed at the speakers so to have the UI flip upside down was very useful. Also the “email support” button in settings didn’t work when I pressed it. Hence my notes here. Otherwise it’s great and I use it in the theater everyday when setting up for a screening.
App does not work
by Gonagain on 2019/06/26 22:16
Payed for the pro upgrade. App shuts down does not work tried to get support no response do not wast your money
Sound
by sal1503 on 2019/06/12 12:13
Great app very helpful for our business which is the trade shows
Number one app
by weeze 63 on 2019/06/07 06:51
I install sound systems in Harley’s and have been using this app for a year or so. I calibrated it with a local bands measuring meter and was surprised it needed very minor adjustments. And no problem with ADDS. Also don’t know if it matters but I am using a iPhone 7 No BS it works great
Better than ever
by CA-KS-RN on 2019/05/29 05:08
I’m just a hobbyist, so I don’t need extreme accuracy. That said, previous apps I’d tried didn’t seem accurate, and compared to a handheld (actual) sound meter, usually weren’t. When I found the non-Pro app, it seemed spot on, and while the ads were ever present, they weren’t annoying (unlike another app that lets you use the trial version for 2 minutes and then stops working and puts up a “buy me” screen with an almost invisible close button). But after using the “free” version for a while, I decided this was worth it. I’ve been enjoying the new features such as the frequency charting feature. Pretty cool seeing what frequency the drum beat is, or why band X seems so much louder despite being a lower decibel reading (more sound closer to 1500 Hz vs 300 Hz).
Thanks for bug fixes
by DaBigBadOtis on 2019/05/28 23:44
Updating review after bug fixes
Fun and good
by Waitcho on 2019/05/27 15:00
I have advanced ear training and worked in studios for a few years. I am by no means an expert but I’m more than an enthusiastic hobbyist. THAT SAID. Love this app. Helps w my new party trick called How Many DBs Are We At Right Now. I don’t go to a lot of parties. Great app.
Fantastic app; Analyst friendly
by earpro 100101 on 2019/05/23 14:27
This is a fantastic app! For someone who works in OSHA hearing conservation the ability to take a photo with the metadata alone is worth the price. Being able export the data to a table is great! The only recommendation I can give would be to include, in the setting, options to customize the metadata for your csv export and camera, specifically, a time stamp (DTG) and frequency, and location that way we can isolate harmful frequencies and conduct a more thorough analysis.
Waste of money
by IranIran on 2019/05/14 05:30
This super overpriced app is missing lots of basic features and doesn’t record correctly. Even with sleep mode record option on, it stops recording when the device sleeps. I want my money back!
Shuts music off when streaming Bluetooth
by LowToneNashville on 2019/05/02 00:30
Defeats the purpose of the app for a lot of users. Please fix.

by Dp373 on 2019/04/22 18:19
Great for monitoring Spl exposure.
Video lacking
by Shap08 on 2019/04/22 16:33
This seems like it could be a really good app. The problem I have is I cannot turn the phone upside down (mic is at the bottom) to take video while holding the phone upside down to avoid hands being near the mic. Also can’t turn it sideways. Some bugs on the video function cause crash as well. Hopefully they add this functionality.
Fixed
by LED4GOD on 2019/04/16 18:21
Bug was fixed that was causing it to crash. Works well.
Update: Opens now (re: Can’t get it to open)
by strobeman4x4 on 2019/04/15 16:18
One more update: Developer just reached out to me to tell me the crash problem is fixed! Changing to five stars! Absolutely awesome customer service! **older review** Below is my old review. I couldn’t get it to open anymore. So I deleted the app and re-downloaded and now it opens. I’m loving the app. Hoping it doesn’t start crashing again **oldest review** iOS v12.1.2 So far I can’t get this to open. It crashes before it opens. I hope I can edit the review once this is fixed.
Love It
by CraigInCO on 2019/04/14 00:06
It’s does what I need again! Thank you to the developers for making it great again! And for letting me know all is good now!
Just downloaded this app
by therev49 on 2019/04/09 20:31
I just downloaded this app and it closes as soon as it starts up. I have an iPhone XS Max, 256 gb storage running iOS 12.2, apple’s latest version. Fix this app or refund the purchase price ASAP. Despite what the developer says or claims, this app was not corrected or fixed as it disappears as soon as the app comes up but stays in the background. When you flick the bottom of the phone screen you can see it but as soon as you lift your finger off the screen it disappears again. What a frustrating piece of crap this app is. If my credit card gets charged for it I will take it up with my card issuer so the charge is removed from account. Should that fail I will file a complaint with the NYS attorney general office as well as the FTC. Yes I am that po’d by this app. This is the first one that I bought where this happened.
Crashes
by CMAWYO on 2019/04/06 15:26
Worked fine when downloaded, then the next day-crashes, open app and it immediately closes. :-(
How accurate is the app?
by Dbeipi on 2019/04/01 21:24
You claim the app is precalibrated for all Apple devices and precision matches “real SPL devices”. What is the accuracy tolerance and compared to what standard? Your statement is meaningless without data. I really like the app, but I must treat the results as estimates of unknown precision.
Auto starts after reset data!
by rockku1234 on 2019/03/19 15:02
When data is reset the meter starts automatically! There is no setting to turn this off. Resulting in inaccurate results due to capturing ambient noise
Frequent Crashes
by Keith80 on 2019/03/14 20:58
Spent around $8 for the pro version, and it crashes all the time.
Great
by Scogmo on 2019/03/09 21:49
My slow WiFi up in the woods didn’t download all the features on iPad at first, weird. When I drove to town my iPhone got the recording data features and when I got home they were on the iPad too. So ignore my 4 star review wishing they had more features. :-)
Won’t work.

Application constantly shuts itself off. Very disappointed.
The delete function for a single report does not work
by mira100000 on 2019/02/12 03:51
It was a good app until the function of seeing the report horizontally was removed. In addition, when you delete one report then close the app, that report comes back.
Real volume feedback
by Scottkins81 on 2019/02/01 17:07
This app allows me to give real time feedback to my students on their volume level during a performance. I like that I can take a photo and attach it to their assignment as proof.
Camera mode crashes the app... FYI
by MusicalMyers on 2019/01/24 23:24
I’m a music and Theatre teacher, and just attended a conference, one session was on the need for hearing protection for music teachers. I panicked, bought some cheaper earplugs for the time being, set an audiology appointment, and purchased this app. I’ve only played with the app, for a few minutes and noticed that on the camera setting the app crashes. Seems like the developer is very responsive though, and is why I went through purchasing the app. Fyi: I’ve played on my piano for just a few minutes and was shocked that I can easily push my piano about 95 decibels! Yikes! Guess, I’m glad I purchased the ear plugs... and the app.
New update = Fixed
by Crazyguy™ on 2019/01/24 18:09
Developers seem to care and fix issues quickly
Modern Dark theme crashes App
by Philip Levin on 2019/01/22 07:43
For those wondering, if you had the modern dark theme enabled, your app will crash. A temporary fix to this would be to redownload the app and leave the classic theme on. Until the developer comes to fix this, we will be stuck with this for now.
Dissatisfy
by Jrwyjr on 2019/01/18 19:07
App stopped working! Don’t waste your money.
New Update Crashes
by Jaybird302 on 2019/01/17 17:46
I really enjoyed using this app for many different uses. However, since the last update it crashes as soon as it starts up. I’m about to bail and find another app. No response from developer when contacted either. Pretty salty about spending money on this, only to have it be a waste. Running on latest IOS on 8+.
Great but crashes
by The Gerharts on 2019/01/17 17:41
I have an iPhone 7 Plus with latest iOS and this sometimes crashes every time I try to open it. If I delete and reinstall it, it works again for a while. One thing it seems is if I change the theme it will crash right away and I have to reinstall again. Otherwise it’s a great app and I use it at work which is occupational health.
Apple mics are too weak for this app to be useful
by MusicianInVegas on 2019/01/17 07:52
Compared to purpose built spectrum analyzers this app falls off considerably from the mids on up. The response time for the spectrum is also way too slow for the kind of money their asking. Spector is on Android gives a faster, more realistic response. Nice app, just a bit disappointing.
To those having trouble -
by AsaBcOvin on 2019/01/15 11:38
Uninstall and reinstall gets it working again!
Why is app crashing on start?
by viper joe on 2019/01/15 05:53
As I’ve seen one other review with the latest upgrade since December 2018 the app is now crashing at start up. I have tried many times like five or 6+ times and it does not start. I am using a iPhone 6S with latest IOS version. I have reported it with an email and have yet to hear a response. The other reviewer states should we just burn this bridge or is the developer you send an update to fix this. I hope the developer wakes up and resolves this. Anyone else have these issues please notify developer. Other than that I would like to write this is a five star app!!! Has been a great app for a couple of years.
App will not even open
by Jaytron7 on 2019/01/15 03:01
I just upgraded to the paid version and the app will not even open. The screen flashed and goes back to the apple home screen. Completely useless.
Stopped working
by audioengineerx on 2019/01/13 17:56
I used this app a lot, but it has stopped working since the update. I contacted the developer 2 weeks ago but still have not heard back from them
Doesn’t work. Won’t open!
by Gattman#1 on 2019/01/12 10:17
After paying $6 for the pro version of the app, it opened once... then never opened again! A waste of money!
Almost 5 stars — every now and then a crash
by iwoolman too on 2019/01/11 20:32
This one helps me protect my nerve-damaged hearing. If it weren’t for the occasional crash, I would give it five stars. My other nit-pick applies to this and other decibel apps: they all report marginally to significantly different levels in the same environments. I’d love to know which is most accurate. Decibel X Pro, though, is easily my favorite. I like the interface, the ability to record, and the quick and easy-to-read comparisons to noise levels in various environments.

Neat app / needs bugs fixed
by Floorlint on 2018/12/29 00:15
With IPhone: App crashes when you try and change view from classic or try to use camera. I’ve had to several times uninstall and re-install. There were lots of free ones, but chose this assuming things would stay up to snuff for a paid APP. Fingers crossed, We’ll see.
Won’t work since the update.

by Debauchee on 2018/12/25 05:54
03NOV2018, I went to a Nine Inch Nails Concert in San Francisco, CA. The warm up act was playing so loud that it showed 122db Z Weighted!!! That is INSTANT Hearing Loss!!!👂 wearing my Ear Plugs under my shooting muffs, that only dropped the sound level 6db or to 117db Z Weighted or Permanent Hearing 👂 after 20 seconds. I ran outside and during the break, confronted the sound crew, showing them the data and demanding the lower the volume else I’ll call OSHA and shut down the tour!!! The dropped it to 105db because of your program!!! Later that week, I got a room upgrade due to noisy neighbours and I got a seat 💺 upgrade because the engines were too loud. I am PROUD to be a HEALTH-NAZI (for fun and profit) and you can be TOO!!!

I just updated to the newest version of Decibel X Pro, and now it won’t open on my phone. Needed it to measure sound levels at a performance tonight and it wouldn’t open. Very disappointing. I’d rate it “0” stars for that malfunction, but zero isn’t an option. The app has worked well prior to this update.

Decibel X Pro review
by DT-48 fan on 2018/12/19 17:58
Meets all the expectations I had after upgrading from the free version. Sure, more accurate equipment exists and the version may not use beam-forming mics available on the newer iPad Pro, but a. this is adequate to many tasks b. it records & the record can be emailed from the app c. it runs n a pice of equipment you probably always carry d. the cost—the cost—the cost cannot be beat.

Works well, convenient, accurate
by Dublinbiker on 2018/12/12 03:53
Very convenient, easy to use, tested its accuracy against machinery I have with factory tested dB levels and is very close. Can’t beat this for $5.
Broken with iOS 12
by xyper on 2018/12/01 00:33
The UI is unusable with iPhone XS and iOS 12: all controls are gone, the only thing visible is a bit of the graphs. Wrote an email to developer, no acknowledgment so far. Was great till iOS 12. Revised: the app now works with XS. So five stars again.
Basic

Excellent
by AnotherGolux on 2018/10/17 07:15
I’m very pleased with this app. I have one small suggestion: I would like to see the app start in Pause mode instead of Record, or perhaps offer this as an option. Thanks!
Worth it! Good App!
by Pizza is my favorite on 2018/10/12 23:11
Don't have much experience with this but the app does what we need it to & does it well to check volume inside our haunted attractions.
Works and Looks Great on iPhone XS Max
by Moleman55 on 2018/10/12 15:27
Time to change my rating: The latest update fixed the App and it’s now working as it used to on the iPhone XS Max and iOS 12.0.1. Great App! Old Review: Decibel X Pro does not display properly or work on iOS 12 on the iPhone XS Max. Hopefully, an update is not too far off! My rating will change if or when corrected.
Now fixed on iOS 12 & iPhone Xs!
by Ted Jerome on 2018/10/12 10:12
[Update: latest version now works as expected—thanks!] Opens to the graph completely full screen with no controls. Labels much too small to be read. Request for help from developer unanswered. In other words, a total waste of money. Caveat emptor.
Meter option not presented
by rob in raleigh on 2018/10/10 00:05
I have tried to install this app several times on my iPhone X’s and all I am presented are the 4 histogram views. I do not see the meter presentation as shown in the examples. Looks like a great app if I could see the meter option and other documentation which is supposed to be part of the application
App UI does not display
by NM00001 on 2018/10/08 19:19
Purchased on an iPhone XS Max. The UI from the example images does not display. App frequently crashes. It does show a decibel readout but the font is tiny and difficult to read, and functionality is very limited. I have emailed support twice since last week with no response. Very disappointed and do not recommend.

Off by 20db
by pengrus on 2018/09/27 05:46

Not optimized for iPhone XS Max

Latest iPhone Version
by bill_mann on 2018/08/27 11:55
I’ve been using this app for a few years and it’s never let me down ... until now. The app is useless on my iPhone X now. Since the latest update, the app crashes upon launch. If I repeatedly relaunch the app I may get lucky after 5 or 6 attempts to launch. Yet after it finally opens its unstable if I switch to a different app and usually crashes as well. Contacted support, 2 weeks ago and there has been no response. Hope someone is reading these reviews because I’d really like to know if I should burn this bridge and find another solution.

Good but has a few bugs.
by mr. nemoto on 2018/08/02 21:56
I use this app for training and assessing vocal intensity for Parkinson's patients. There are 3 problems that need to be fixed. One is the data on the summary report doesn't fit on the "page" so the numbers are hard to read. The second problem is that when data is cleared, it immediately starts recording again and the pause button has to be hit quickly. And finally, even the slightest upward swipe (always on accident) flips you into a different screen which is annoying and disruptive.
Needs serious work
by Number1BostonFan on 2018/07/26 15:06
Was at a concert last night and took some pictures showing the measured dB. I was extremely disappointed when I found out the pics weren’t automatically saved to my photos. What’s the point of taking pics if you have to manually choose to save the pics?

Best SPL App I’ve Used
by B.J.S. on 2019/07/07 21:50
This is the best SPL meter app I’ve used. Well worth the purchase. The only suggestion I have is that it doesn’t rotate 180 degrees on the iPhone XS Max like it did on my old iPhone 6. I like to have the microphone at the bottom of the phone pointed at the speakers so to have the UI flip upside down was very useful. Also the “email support” button in settings didn’t work when I pressed it. Hence my notes here. Otherwise it’s great and I use it in the theater everyday when setting up for a screening.

If my credit card gets charged for it I will take it up with my card issuer so the charge is removed from account. Should that fail I will file a complaint with the NYS attorney general office as well as the FTC. Yes I am that po’d by this app. This is the first one that I bought where this happened.
Camera mode crashes the app... FYI
by MusicalMyers on 2019/01/24 23:24
I’m a music and Theatre teacher, and just attended a conference, one session was on the need for hearing protection for music teachers. I panicked, bought some cheaper earplugs for the time being, set an audiology appointment, and purchased this app. I’ve only played with the app, for a few minutes and noticed that on the camera setting the app crashes. Seems like the developer is very responsive though, and is why I went through purchasing the app. Fyi: I’ve played on my piano for just a few minutes and was shocked that I can easily push my piano about 95 decibels! Yikes! Guess, I’m glad I purchased the ear plugs... and the app.
Good but has a few bugs.
by mr. nemoto on 2018/08/02 21:56
I use this app for training and assessing vocal intensity for Parkinson's patients. There are 3 problems that need to be fixed. One is the data on the summary report doesn't fit on the "page" so the numbers are hard to read. The second problem is that when data is cleared, it immediately starts recording again and the pause button has to be hit quickly. And finally, even the slightest upward swipe (always on accident) flips you into a different screen which is annoying and disruptive.
Fantastic app; Analyst friendly
by earpro 100101 on 2019/05/23 14:27
This is a fantastic app! For someone who works in OSHA hearing conservation the ability to take a photo with the metadata alone is worth the price. Being able export the data to a table is great! The only recommendation I can give would be to include, in the setting, options to customize the metadata for your csv export and camera, specifically, a time stamp (DTG) and frequency, and location that way we can isolate harmful frequencies and conduct a more thorough analysis.
Almost 5 stars — every now and then a crash
by iwoolman too on 2019/01/11 20:32
This one helps me protect my nerve-damaged hearing. If it weren’t for the occasional crash, I would give it five stars. My other nit-pick applies to this and other decibel apps: they all report marginally to significantly different levels in the same environments. I’d love to know which is most accurate. Decibel X Pro, though, is easily my favorite. I like the interface, the ability to record, and the quick and easy-to-read comparisons to noise levels in various environments.
Great noise monitor
by KeikoTsunami on 2018/04/28 21:55
I occasionally need to monitor noise levels at home or in classrooms when I’m substitute teaching. So I’m a novice at this, although I am a scientist in other areas. This APP does everything I need: records noise levels, lets me adjust the parameters, such maximum acceptable noise level, and I can download the data. It defines & explains everything. It is calibrated. The only thing it has no effect on is my 4 cats’ level of meowing. If only it could feed them.... I’m thrilled with this APP!
New features are great
by Charlie19Clay on 2019/11/03 23:35
The new features are all good, some are just fun, and some helpful. I have regular access to two pro decibel meters (both B&K with recent calibrations) and this app consistently shows very similar results with just a small calibration, which can be made very easily within the app (I add 1.3 decibels) I consider it accurate and would rely on the results if need be.
Latest iPhone Version
by bill_mann on 2018/08/27 11:55
I’ve been using this app for a few years and it’s never let me down ... until now. The app is useless on my iPhone X now. Since the latest update, the app crashes upon launch. If I repeatedly relaunch the app I may get lucky after 5 or 6 attempts to launch. Yet after it finally opens its unstable if I switch to a different app and usually crashes as well. Contacted support, 2 weeks ago and there has been no response. Hope someone is reading these reviews because I’d really like to know if I should burn this bridge and find another solution.
It keeps aborting
by MarieAnnet on 2019/07/16 12:42
I bought the Pro because I wanted to record a few “background” sounds that — with my new hearing aids — sound so much louder (coffee maker, a/c, fans, water, etc. I’m returning soon to get so my hearing aids adjusted and thought these recordings would help. But after saving a recording, the program aborted. And aborted. And aborted. Every time I went back in, it just ended. I was finally able to get it to stay open to record once again, but after each recording it would abort again it was a minute or more before it would stay open. I’m not impressed. But I’d like to be.
A useful tool
by Radjin on 2018/03/30 13:51
On fast mode it’s pretty good at detecting sounds your ear cannot, leaks in systems, failing bearings. I hope in an update the orientation is enhanced. When I attempt to point the microphone at the source for better location the screen only goes as far as landscape. I would also like to switch between different settings to compare without having to go into a separate settings screen interrupting my work.
Decibel X Pro review
by DT-48 fan on 2018/12/19 17:58
Meets all the expectations I had after upgrading from the free version. Sure, more accurate equipment exists and the version may not use beam-forming mics available on the newer iPad Pro, but a. this is adequate to many tasks b. it records & the record can be emailed from the app c. it runs n a pice of equipment you probably always carry d. the cost—the cost—the cost cannot be beat.
Why is app crashing on start?
by viper joe on 2019/01/15 05:53
As I’ve seen one other review with the latest upgrade since December 2018 the app is now crashing at start up. I have tried many times like five or 6+ times and it does not start. I am using a iPhone 6S with latest IOS version. I have reported it with an email and have yet to hear a response. The other reviewer states should we just burn this bridge or is the developer you send an update to fix this. I hope the developer wakes up and resolves this. Anyone else have these issues please notify developer. Other than that I would like to write this is a five star app!!! Has been a great app for a couple of years.
Needs serious work
by Number1BostonFan on 2018/07/26 15:06
Was at a concert last night and took some pictures showing the measured dB. I was extremely disappointed when I found out the pics weren’t automatically saved to my photos. What’s the point of taking pics if you have to manually choose to save the pics?
Works and Looks Great on iPhone XS Max
by Moleman55 on 2018/10/12 15:27
Time to change my rating: The latest update fixed the App and it’s now working as it used to on the iPhone XS Max and iOS 12.0.1. Great App! Old Review: Decibel X Pro does not display properly or work on iOS 12 on the iPhone XS Max. Hopefully, an update is not too far off! My rating will change if or when corrected.
Great but crashes
by The Gerharts on 2019/01/17 17:41
I have an iPhone 7 Plus with latest iOS and this sometimes crashes every time I try to open it. If I delete and reinstall it, it works again for a while. One thing it seems is if I change the theme it will crash right away and I have to reinstall again. Otherwise it’s a great app and I use it at work which is occupational health.
Great
by Scogmo on 2019/03/09 21:49
My slow WiFi up in the woods didn’t download all the features on iPad at first, weird. When I drove to town my iPhone got the recording data features and when I got home they were on the iPad too. So ignore my 4 star review wishing they had more features. :-)
Video lacking
by Shap08 on 2019/04/22 16:33
This seems like it could be a really good app. The problem I have is I cannot turn the phone upside down (mic is at the bottom) to take video while holding the phone upside down to avoid hands being near the mic. Also can’t turn it sideways. Some bugs on the video function cause crash as well. Hopefully they add this functionality.
Number one app
by weeze 63 on 2019/06/07 06:51
I install sound systems in Harley’s and have been using this app for a year or so. I calibrated it with a local bands measuring meter and was surprised it needed very minor adjustments. And no problem with ADDS. Also don’t know if it matters but I am using a iPhone 7 No BS it works great
Newest version
by rbe7561 on 2019/09/22 21:23
I have used the app for quite awhile but the newest version that I just installed on my new iPhone 11 has a 15-20 second delay for the sounds to be registered on the meter and graph. I was hopeful that a setting would correct this but so far nothing corrects that. I hope that the developer is aware of this and can correct it in the next release.
Update: Opens now (re: Can’t get it to open)
by strobeman4x4 on 2019/04/15 16:18
One more update: Developer just reached out to me to tell me the crash problem is fixed! Changing to five stars! Absolutely awesome customer service! **older review** Below is my old review. I couldn’t get it to open anymore. So I deleted the app and re-downloaded and now it opens. I’m loving the app. Hoping it doesn’t start crashing again **oldest review** iOS v12.1.2 So far I can’t get this to open. It crashes before it opens. I hope I can edit the review once this is fixed.
It is simple and works
by Lovejoy Ranch on 2017/11/16 04:18
I got this ap because the screen shot shows sound pressure levels on an octave chart and a historical graph. I wanted to record this spectrum, or at least capture averages for each octave, but it turns out it only plots the average. It does show instantaneous octave bands.
Great tool
by ugly approach on 2017/11/21 23:36
Used this for mixing sound at church. We have some folks who want the sound to be louder due to hearing loss. Used this app (Pro version) to show what the levels are and made everyone happy without touching the mix. Made my life much better!
THE best app
by John11: on 2019/07/27 02:29
I’ve tried 4 other meter apps. None compare. How much is your hearing worth?! Let me rephrase... is the price of this app too much $ for a lifetime of hearing damage?!!! So many tools to choose from... camera, meters, guides. All on this app. Easy to use... Nice job developers!
Great App, when you think things are too loud
by Pgeorge1944 on 2017/11/14 22:12
You are in a Bar or a Pub and you think things are too loud. You can prove it with this App. I have found most Pubs are at 90db or above. I have used it to have the management lower the music sound.
Simple function - amazing app!
by Gene-Photo-Audio on 2019/11/15 20:37
For something as simple as showing current dB level this app does an amazing job of showing a great UI with tons of options and features on how to use and display the data. Best dB app out!
Real volume feedback
by Scottkins81 on 2019/02/01 17:07
This app allows me to give real time feedback to my students on their volume level during a performance. I like that I can take a photo and attach it to their assignment as proof.
Now fixed on iOS 12 & iPhone Xs!
by Ted Jerome on 2018/10/12 10:12
[Update: latest version now works as expected—thanks!] Opens to the graph completely full screen with no controls. Labels much too small to be read. Request for help from developer unanswered. In other words, a total waste of money. Caveat emptor.
Fun and good
by Waitcho on 2019/05/27 15:00
I have advanced ear training and worked in studios for a few years. I am by no means an expert but I’m more than an enthusiastic hobbyist. THAT SAID. Love this app. Helps w my new party trick called How Many DBs Are We At Right Now. I don’t go to a lot of parties. Great app.
Neat app / needs bugs fixed
by Floorlint on 2018/12/29 00:15
With IPhone: App crashes when you try and change view from classic or try to use camera. I’ve had to several times uninstall and re-install. There were lots of free ones, but chose this assuming things would stay up to snuff for a paid APP. Fingers crossed, We’ll see.
Settings crash - fixed
by Colosaldrummer on 2017/09/28 16:26
Update: They have fixed the issue and it works well now. Running 10.3.3 on 6+ and you can't change anything in the settings menu without it crashing to the home screen.
Excellent
by AnotherGolux on 2018/10/17 07:15
I’m very pleased with this app. I have one small suggestion: I would like to see the app start in Pause mode instead of Record, or perhaps offer this as an option. Thanks!
Works as advertised
by Herbstar on 2018/05/20 18:42
Apps should work as intended. The science and tech in this one does. I haven’t had the equipment to test or adjust its accuracy but it appears to be correct out of the box. I recommend it.
Proved my point
by Kerrybatdog on 2018/06/06 03:51
I got this app to measure noise from my upstairs neighbors to prove to management how loud they are. Did exactly what I needed it to do! Now I’m a bit obsessed and often find myself measuring the dB levels around me. Great little app.
Crashes
by 458079 on 2018/11/05 03:22
Crashes way too often. Paid 4.99 for the pro hoping that would resolve the issue but it didn’t.
Great App
by AVG99 on 2019/09/29 12:28
I have always had a sound meter usually it was a old clunky one from radioshack with this app I had a modern way to check sound levels. Good app, good update.
App keeps crashing
by recboxer on 2017/08/18 15:07
I'm running iOS 10.3.3 on an iPhone 6. Whenever I try to modify any of the settings, such as change from the default Z weighting to A weighting, the app crashes.
Back to the drawing board
by Copier guy 123 on 2019/08/28 21:43
Ok 8.00 is here. Yes I use this professionally (not exclusively). Ok so using pro I already had no ads. You have frequencies across the top but then you plop dumb test right over them like “quiet home”. All new dosimeter!!! Except it used to work fine and now doesn’t work at all. All attempts to switch to dosimeter get no reaction. Thanks for screwing up what was the best sound meter on the market. IPhone 8.
New update = Fixed
by Crazyguy™ on 2019/01/24 18:09
Developers seem to care and fix issues quickly
Works well, convenient, accurate
by Dublinbiker on 2018/12/12 03:53
Very convenient, easy to use, tested its accuracy against machinery I have with factory tested dB levels and is very close. Can’t beat this for $5.
Very useful
by patricknss on 2018/06/24 17:32
Great to have in order to understand level of noise environment. Proves a device to evaluate various noise levels of products being considered for purchase
Awesome!
by Ear Cleaner on 2019/08/17 18:45
Elegant, everything a professional needs, as well as anyone interested in how sound looks and feels...a must in this day and age of sound pollution!
To those having trouble -
by AsaBcOvin on 2019/01/15 11:38
Uninstall and reinstall gets it working again!
New Update Crashes
by Jaybird302 on 2019/01/17 17:46
I really enjoyed using this app for many different uses. However, since the last update it crashes as soon as it starts up. I’m about to bail and find another app. No response from developer when contacted either. Pretty salty about spending money on this, only to have it be a waste. Running on latest IOS on 8+.
Worth it! Good App!
by Pizza is my favorite on 2018/10/12 23:11
Don't have much experience with this but the app does what we need it to & does it well to check volume inside our haunted attractions.
Video bugs
by Bekuz_Ikan on 2019/08/29 14:55
I see video ability is still really buggy, and it still won’t take landscape full screen videos with DB overlaid. Hopefully that can get resolved. I’m surprised more people aren’t needing or see the need to take a video of what is making the sound.
App UI does not display
by NM00001 on 2018/10/08 19:19
Purchased on an iPhone XS Max. The UI from the example images does not display. App frequently crashes. It does show a decibel readout but the font is tiny and difficult to read, and functionality is very limited. I have emailed support twice since last week with no response. Very disappointed and do not recommend.
