Used to prove noise issue to landlord
by reinoldrr on 2020/10/14 19:36
I have sensitive hearing, my landlord does not, and I used this app to prove noise disturbance from air conditioning. The evidence saved me $3000 in moveout fees. Very grateful.

Serious
Love it !

I can make sounds and it is soooooooo cooool
Missing major feature
by Adhdgj on 2020/06/09 16:39
The analyzer works fine, but what good is an analyzer without a signal generator? Tried to use a separate app, but when I switch to this app it disables output of signal generator app, so it’s really not useful to me at all. Good thing I didn’t pay for the pro version
Nice tool for speaker calibration
by JohnDraez on 2020/05/21 00:12
Using this app along with a YouTube frequency sweep to see peaks & nulls in my home theater. Would love to have the option for c or z weighting which I’d gladly pay extra for, but even with just a weighting it’s been very useful.
Clean Design... but wanted Line In option
by Killertone on 2020/05/16 13:39
It gets four stars because IF you only wanted to use the not so great built-in microphone of your device then it seems to work very well. I was actually willing to pay for a way to unlock a Line-In feature but nothing told me that the feature exists. The fact that the spectrum plot can hold the peaks is a real nice and makes your app more useful. The pop up is super annoying, but being an App developer myself...I understand how selfish people just expect a great feature rich App to be all for FREE (i gave up thinking i could be paid for all my hard work). Just for fun, you can check out my Free iPhone App FlipNshare ProVideo. I did uninstall the app only because i need Line-In feature, please let me know if it’s actually available.
Audio Spectrum Analyzer
by DisasterIV on 2020/04/17 20:22
Do no see modes that I had before buying. I do see how to change scales, save or print a display. FFT resolution has no change. Fail to see advantage in buying it. Donald Fuelling
Annoying, but maybe useful
by Board gamer 696969 on 2020/04/07 19:45
Unsure if there is a timed interval of the pop up advertisement to purchase the “Pro” version or if it is based on how many times you touch something in the app, but it gets very frustrating trying to adjust a complex audio system, while constantly being asked if would like to buy the pro version, which runs $8.99. Annoyances aside, the frequencies being gathered (by 3 additional Apple products, 4 total) seem to be less accurate than they should be. Adjusting 250hz on my head unit’s EQ effected the 125hz bar on the graph in the app. Actively looking for another app that can be more successful.
Best one
by Lesterphlatt on 2020/03/21 17:17
This is the best free analyzer I have found.
works but..
by Dr. Swice on 2020/03/07 18:18
this works but it doeant accept audio in just microphone. so for an audio engineer using to check a mix is usless bc the aimbent room noise throws everything off. would be cool if i could use another imput source other than microphone.
Nice App - Annoying Ad
by reviewerdan on 2020/02/23 00:25
Very nice app. Gave me exactly what I was looking for, a way to tune my small living room surround sound system. The only gripe is the completely annoying “buy me, buy me” pop up ad that covers the entire screen every 30 seconds. Make the purchase option an icon in options and stop covering up the screen. Then this app will be a perfect 5 stars.
Controlled limiter
by jonathanclark123456 on 2020/02/06 21:57
They purposely designed the app so it Only operates at half the accuracy as it would if you bought it.

Spectrum review
by bebob zell on 2020/01/26 21:16
Very difficult to ascertain the app value as it keeps quickly jumping to please buy the pro version. That said I’ll try again to get a pink noise reading on my speakers
Great
by ianbrucebass on 2019/12/08 15:29
Thanks
Great
by bardorfb on 2019/11/22 17:51
Great rat for free. Helped me tune my car audio system.
Non stop interuption
by 12data on 2019/11/04 18:04
I get it that a premium upgrade is available. This app reminds you about every 40 seconds that a upgrade is available. Terrible
Why not Pro on iOS and iPadOS?
by JML54 on 2019/10/24 20:45
All my other apps that require unlocking or add removal do that on both iPad and iPhone but not this one!
Epic failure
by Tillerkins on 2019/09/11 18:20
Needed help using the app; sent request to developer- the only response “no support available”
Nice app but...
by Ponyong888 on 2019/09/01 08:52
Nice App. But, FREE is just the same as PRO not much difference. Hope improve more so I can clearly see the difference.
Great tool
by Rochmon on 2019/08/29 15:01
Easy to use and cost effective. I upgraded to premium and the unlocked version gives me lots of flexibility. Easy to use. I just have to leave my screen up. Lol

“Upgrade to Pro” ruins it.
by j torqe on 2019/08/01 12:47
This app works great and has a very nice interface. The only and very big downfall is every 2 minutes, I timed it, the app will stop working and a full page ad to “upgrade to pro version” covers the entire screen. You then have to press the close button to get rid of it and your good to go. Then 2 minutes later the same thing pops up. This will happen every 2 min as long as you are using the app. Very very distracting and annoying. If it was for this it would be 5 stars.
Works but nags constantly
by SweetFan123 on 2019/07/24 15:11
This app works as it should but I have uninstalled it because it was so busy nagging me to buy the pro version I didn’t have time to love it enough to buy it. Additionally, it will not allow music to play on the same device that is running the app. This may be unavoidable but disappointing.
Popup for Pro Every Few Minutes
by musicmosquito on 2019/07/15 14:11
App works great, the graphs and functions are decent and well laid out. The one big frustration is the CONSTANT popup asking me to buy the pro version. Left the graph running on my desk for a moment, it popped up. Close it, watch the graph. A minute later, it popped up again. It ended up popping up and blocking the entire screen four times in under ten minutes. If the popup was less frequent (maybe on app launch and every ten minutes or less), or costs less ($8.99 for pro), I’d rate this better. I’m not paying for the pro version simply due to how annoyed I was at the pushy attitude of the app, and have since uninstalled it.
Wayyyy too many upgrade prompts
by Will Scrillz on 2019/07/10 23:14
Everytime I actually try to use this when I need it, it is essentially unusable because it takes me away from the RTA to try to get me to upgrade. Also not a fan of the interface though its hard to tell if I would get used to it since I am constantly interrupted. I really miss my old Spectrum Analyzer app that was on Android and worked flawlessly for professional work but the search will definitely continue, this is not the replacement.
Great App to Analyze a Strange Noise in Home
by jimlistens on 2019/07/06 01:51
We had encountered a buzzing noise that came and went. The noise was coming from the ceiling my office like it was originating in attic. Was it a bee hive or hornet infestation, wind causing vibrations in eves or loose roof components or more serious issue some kind of electrical hum or buzz. I thought if only I had a spectrum analyzer I could rule out an electrical issue if the noise was 60 HZ or a 120 Hz harmonic. So I thought my phone has a microphone and it certainly could analyze sound . So I found this App for my iphone. It showed the primary vibration was 101 HZ so I felt relieved. But what was it? The room next door was a bathroom and the noise was louder but still coming from the ceiling. So then I thought toilets can cause funny noises. I took off the tank lid and waited until the noise was loudest and touched the float arm hitch was connected to the auto shutoff valve . It was vibrating like crazy and the noise went away . But I still could not understand why the noise was coming from above. Then I thought the plumbing stack vent was just like a pipe in a pipe organ. The vibration in the tank made the column of air in the stack vent resonate. Strangest annoying sound and plumbing issue I have ever heard of in my life. I fixed it by turning the float adjustment screw just a bit. The technology in a smart phone seems to be unlimited.
Nice app
by AimesJainchill on 2019/06/15 20:25
Shows detailed live ambient sound across frequency spectrum.
Annoyware - every 2 mins go pro popup
by Ignacj on 2019/05/14 21:45
How many times will you ask me to go pro before I give up on your app? Bottom line is that you lost a potential pro customer that you wanted so bad. Less is more.
Paid. Not get paid version
by Tx64376 on 2019/05/11 16:53
So so not happy about pay and did not get paid version
Good analyzer but very user unfriendly
by Pagodafan on 2019/05/08 03:29
No manual, 4 short paragraphs in help menu provide very little help. Impossible to identify frequencies of multiple peaks because cursor line jumps to wherever it wants. No save function for each spectrum (except screen shot). Questions to developer by email remain unanswered.
Useful tool but lacks that one thing...
by DanThrman on 2019/03/27 14:25
The complainers about the purchase ad are ridiculous. People don’t make apps without an expectation of getting paid for them. The loudest frequency tracking feature is super cool. The lack of a dB-C weighting is keeping me from buying. Level measurement for music needs it. If that ever shows up I’ll buy.
Could be better if not for pop up message
by fuzz6704 on 2019/03/22 16:51
Turn off the “get pro” notification that pops up all of the time! Great app otherwise but I’m deleting soon because of the pop up.
Eh
by sheyeurjjdjcur on 2019/03/08 15:33
Not What I’m looking for at all
Worst scam ever
by Orazaleo on 2019/03/08 10:00
This app basically obligates you to buy the full thing or else, they give you adds every 25 seconds LITERALLY!!! Even when the phone is on airplane mode. Not fun to use, and not clear or user friendly. Definitively erasing it FOR GOOD!!
Its fine...
by Hdgfgbebvbs on 2019/02/09 03:55
The spectrometer it self is great, but how your app adds it in is horrible. Every minute, it tells me to get the pro version which makes the app useless. The fristrating part is that it doesn’t even show any real ads. All it shows me is to upgrade to pro. Additionally, I don’t need or want ANY of the pro’s features. There are no ads, the accuracy is good enough and I don’t even know what FFT & RTA is! Make an option to just shush it up!
Well done!!
by LittleSt3vi3 on 2019/02/07 13:35
Excellent, excellent software, FFT and sound analysis work Elena... the tools are great... beautifully done! The iPhone 7 microphone is well calibrated. Using the 8k FFT in high resolution work, believe you could go to a 16k no problem. Thank you very much!
Works great!
by GoFast222 on 2019/01/13 15:03
Works great setting up church sanctuaries!!
Very Unhappy User
by Gabreael on 2019/01/13 06:55
For the pro version it cost $8.99. It might be worth it if you could hear it but you cannot hear anything I went to analyze something and listen to the play back and you can hear nothing not nothing. How can you know what it analyzed if you cannot hear it play back? It could just be sitting there rolling numbers your direction? If you use any analyzer on your PC or desktop you can hear it why can you not hear this one? So thank you for ripping me off of nine dollars!
Beware of Russian Malware
by bmrosen45 on 2018/12/22 01:33
I have tried the program and it appears to work well. I have not compare with professional equipment to verify its result. However I have serious reservations using a program developed in Russia. The Russian troll company has already been linked to false news during the election. Given the app requires access to your phone’s microphone it can easy be used to listen in on private conversations. Buyer beware is my point.
Wind Chime help

Can’t even use
by don't wanna nickname on this on 2018/10/15 04:26
Asked me three times every five minutes all ways for upgrade to pro version
Excellent app, especially for the price.
by JParker on 2018/08/10 03:25
Perhaps the best free spectrum analysis app out there. Very accurate and useful. Highly recommended if you have need for such a thing.
Not accurate for RTA use
by Matt Selinger on 2018/08/07 05:49
This app looks nice, but I can’t get much use out of it. Frequency data below 100 Hz is not accurate. Disappointed I paid to use the “Pro “ version. Deleting this one from my iPad.
Exhaust
by Greg Nog on 2018/08/06 02:28
I used this app for simply testing the sound level of my exhaust to check if it was too loud for my state standards, which, thanks to this app, I know it is not
Works Great
by Larshjarshon on 2018/07/15 18:47
I use this to help ring out every room before performers ever get to the show. Maximizing gain before feedback is as simple as pushing the fader nice and slow until you hear the ringing start, then the app tells you exactly what you need to take out. Invaluable if you don’t have a digital mixer with a spectrum analyzer built in.
Doesn’t work right for me
by TFozb on 2018/07/12 02:09
I gave the app 2 stars for its potential greatness but as of now the frequency value displayed at the top doesn’t change when the cursor is moved, so I can’t use it to pinpoint frequencies like I’d planned.
Difficult to evaluate
by tailsawaggin on 2018/06/13 02:37
An upgrade nag pops up every few seconds, interrupting whatever you’re doing and forcing you to deal with it. Can’t meaningfully evaluate an app under those operating conditions. Deleted after being interrupted four times in less than five minutes.
No good
by king dog daddy on 2018/05/30 20:19
This app does not work, when my car stereo is on it freezes.
GREATEST Free App so far!
by ask4mask on 2018/05/26 10:08
Awesome App and It's Free! LOVE it! Have tried many other but nothing like this for Free, as it was free it pushes me to upgrade to the full version even though it's not necessary as this free version gives me everything I need! A BIG 👍
Not very useful
by dworsnup on 2018/04/03 19:22
This app asks you to upgrade to premium every few seconds interrupting any measurements you are trying to make. I’m not saying the utility should necessarily be free, but the free version of this utility has no actual utility.
Very nice
by Ringomar on 2018/03/05 01:42
I can see all noise frequency with this application
Invalid readings
by hoppeth on 2018/02/06 01:47
Frequency reading is way off, it's broken and of no use
Octave Band RTA Isn’t Working Correctly
by JesterXR on 2017/12/12 17:05
Really like the app however I noticed the frequency numbers do not match the spectrum in the RTA mode. The spectrum looks accurate but the numerical results are not. Also the feedback button doesn’t work under help so I couldn’t reach out to the developer that way to explain the issue. I think if they fix that issue this will be a great app.
Good analyzer- don’t try it in a meeting though!
by Knyknkn on 2017/11/19 18:13
I was trying free version out running audio in a large meeting when suddenly an ad blaring loud sound effects started playing. Very embarrassing, not cool for an audio app, deleted immediately. Analyzers seemed decent
Spectrum is very good
by Rhstools on 2017/11/07 04:38
I bought a Reed meter which was very good but it was $200. This app seems better for $5
iphone7s plus bug
by Kelotrbrbr on 2017/10/22 13:01
It doesn’t read the correct frequency on an iPhone 6S plus. It’s off by a factor of more than 10. The bar chart is accurate but the display at the top doesn’t coincide with the bar chart.
very good
by Carmen E. Barnett on 2017/10/02 15:41
Very simple, no ads. Wish there were color options, but it is the only analyzer for internally played music.
Very good app
by John I. Bullard on 2017/10/02 15:39
I used to use this alot for music because i always was intested in the way spectrum works and this is my dream app. Very simple yet so powerful
Why wait?
by James C. Bayer on 2017/10/01 16:36
I have been using this for months! Best Spectrum Analyzer I could find. Works very well. Has calibration options. What more could you need?
Very nice
by David H. Betts on 2017/09/30 15:03
Generally more stable than other similar apps, more customisation, and overall better aesthetics
Great app
by Renee V. Dover on 2017/09/30 14:59
This app seems very good. Various options are very useful. I suggest the developers to add few more add ons in the upcoming updates
Good app
by Jeffrey G. Brown on 2017/09/29 15:36
If you need to look at your audio systems frequency response this will do the trick. The interface is simple and configurable
Great app
by James L. West on 2017/09/29 15:30
Highly configurable, excellent features, very effective.Best app I've found for noise measurement.

Beware of Russian Malware
by bmrosen45 on 2018/12/22 01:33
I have tried the program and it appears to work well. I have not compare with professional equipment to verify its result. However I have serious reservations using a program developed in Russia. The Russian troll company has already been linked to false news during the election. Given the app requires access to your phone’s microphone it can easy be used to listen in on private conversations. Buyer beware is my point.

by Adhdgj on 2020/06/09 16:39
The analyzer works fine, but what good is an analyzer without a signal generator? Tried to use a separate app, but when I switch to this app it disables output of signal generator app, so it’s really not useful to me at all. Good thing I didn’t pay for the pro version
Nice tool for speaker calibration
by JohnDraez on 2020/05/21 00:12
Using this app along with a YouTube frequency sweep to see peaks & nulls in my home theater. Would love to have the option for c or z weighting which I’d gladly pay extra for, but even with just a weighting it’s been very useful.
Clean Design... but wanted Line In option
by Killertone on 2020/05/16 13:39
It gets four stars because IF you only wanted to use the not so great built-in microphone of your device then it seems to work very well. I was actually willing to pay for a way to unlock a Line-In feature but nothing told me that the feature exists. The fact that the spectrum plot can hold the peaks is a real nice and makes your app more useful. The pop up is super annoying, but being an App developer myself...I understand how selfish people just expect a great feature rich App to be all for FREE (i gave up thinking i could be paid for all my hard work). Just for fun, you can check out my Free iPhone App FlipNshare ProVideo. I did uninstall the app only because i need Line-In feature, please let me know if it’s actually available.

Annoying, but maybe useful
by Board gamer 696969 on 2020/04/07 19:45
Unsure if there is a timed interval of the pop up advertisement to purchase the “Pro” version or if it is based on how many times you touch something in the app, but it gets very frustrating trying to adjust a complex audio system, while constantly being asked if would like to buy the pro version, which runs $8.99. Annoyances aside, the frequencies being gathered (by 3 additional Apple products, 4 total) seem to be less accurate than they should be. Adjusting 250hz on my head unit’s EQ effected the 125hz bar on the graph in the app. Actively looking for another app that can be more successful.

Nice App - Annoying Ad
by reviewerdan on 2020/02/23 00:25
Very nice app. Gave me exactly what I was looking for, a way to tune my small living room surround sound system. The only gripe is the completely annoying “buy me, buy me” pop up ad that covers the entire screen every 30 seconds. Make the purchase option an icon in options and stop covering up the screen. Then this app will be a perfect 5 stars.

“Upgrade to Pro” ruins it.
by j torqe on 2019/08/01 12:47
This app works great and has a very nice interface. The only and very big downfall is every 2 minutes, I timed it, the app will stop working and a full page ad to “upgrade to pro version” covers the entire screen. You then have to press the close button to get rid of it and your good to go. Then 2 minutes later the same thing pops up. This will happen every 2 min as long as you are using the app. Very very distracting and annoying. If it was for this it would be 5 stars.
Works but nags constantly
by SweetFan123 on 2019/07/24 15:11
This app works as it should but I have uninstalled it because it was so busy nagging me to buy the pro version I didn’t have time to love it enough to buy it. Additionally, it will not allow music to play on the same device that is running the app. This may be unavoidable but disappointing.
Popup for Pro Every Few Minutes
by musicmosquito on 2019/07/15 14:11
App works great, the graphs and functions are decent and well laid out. The one big frustration is the CONSTANT popup asking me to buy the pro version. Left the graph running on my desk for a moment, it popped up. Close it, watch the graph. A minute later, it popped up again. It ended up popping up and blocking the entire screen four times in under ten minutes. If the popup was less frequent (maybe on app launch and every ten minutes or less), or costs less ($8.99 for pro), I’d rate this better. I’m not paying for the pro version simply due to how annoyed I was at the pushy attitude of the app, and have since uninstalled it.
Wayyyy too many upgrade prompts
by Will Scrillz on 2019/07/10 23:14
Everytime I actually try to use this when I need it, it is essentially unusable because it takes me away from the RTA to try to get me to upgrade. Also not a fan of the interface though its hard to tell if I would get used to it since I am constantly interrupted. I really miss my old Spectrum Analyzer app that was on Android and worked flawlessly for professional work but the search will definitely continue, this is not the replacement.
Great App to Analyze a Strange Noise in Home
by jimlistens on 2019/07/06 01:51
We had encountered a buzzing noise that came and went. The noise was coming from the ceiling my office like it was originating in attic. Was it a bee hive or hornet infestation, wind causing vibrations in eves or loose roof components or more serious issue some kind of electrical hum or buzz. I thought if only I had a spectrum analyzer I could rule out an electrical issue if the noise was 60 HZ or a 120 Hz harmonic. So I thought my phone has a microphone and it certainly could analyze sound . So I found this App for my iphone. It showed the primary vibration was 101 HZ so I felt relieved. But what was it? The room next door was a bathroom and the noise was louder but still coming from the ceiling. So then I thought toilets can cause funny noises. I took off the tank lid and waited until the noise was loudest and touched the float arm hitch was connected to the auto shutoff valve . It was vibrating like crazy and the noise went away . But I still could not understand why the noise was coming from above. Then I thought the plumbing stack vent was just like a pipe in a pipe organ. The vibration in the tank made the column of air in the stack vent resonate. Strangest annoying sound and plumbing issue I have ever heard of in my life. I fixed it by turning the float adjustment screw just a bit. The technology in a smart phone seems to be unlimited.

The complainers about the purchase ad are ridiculous. People don’t make apps without an expectation of getting paid for them. The loudest frequency tracking feature is super cool. The lack of a dB-C weighting is keeping me from buying. Level measurement for music needs it. If that ever shows up I’ll buy.

The spectrometer it self is great, but how your app adds it in is horrible. Every minute, it tells me to get the pro version which makes the app useless. The fristrating part is that it doesn’t even show any real ads. All it shows me is to upgrade to pro. Additionally, I don’t need or want ANY of the pro’s features. There are no ads, the accuracy is good enough and I don’t even know what FFT & RTA is! Make an option to just shush it up!
Well done!!

For the pro version it cost $8.99. It might be worth it if you could hear it but you cannot hear anything I went to analyze something and listen to the play back and you can hear nothing not nothing. How can you know what it analyzed if you cannot hear it play back? It could just be sitting there rolling numbers your direction? If you use any analyzer on your PC or desktop you can hear it why can you not hear this one? So thank you for ripping me off of nine dollars!

Really like the app however I noticed the frequency numbers do not match the spectrum in the RTA mode. The spectrum looks accurate but the numerical results are not.

I’m not paying for the pro version simply due to how annoyed I was at the pushy attitude of the app, and have since uninstalled it.
Annoying, but maybe useful
by Board gamer 696969 on 2020/04/07 19:45
Unsure if there is a timed interval of the pop up advertisement to purchase the “Pro” version or if it is based on how many times you touch something in the app, but it gets very frustrating trying to adjust a complex audio system, while constantly being asked if would like to buy the pro version, which runs $8.99. Annoyances aside, the frequencies being gathered (by 3 additional Apple products, 4 total) seem to be less accurate than they should be. Adjusting 250hz on my head unit’s EQ effected the 125hz bar on the graph in the app. Actively looking for another app that can be more successful.
“Upgrade to Pro” ruins it.
by j torqe on 2019/08/01 12:47
This app works great and has a very nice interface. The only and very big downfall is every 2 minutes, I timed it, the app will stop working and a full page ad to “upgrade to pro version” covers the entire screen. You then have to press the close button to get rid of it and your good to go. Then 2 minutes later the same thing pops up. This will happen every 2 min as long as you are using the app. Very very distracting and annoying. If it was for this it would be 5 stars.
Well done!!
by LittleSt3vi3 on 2019/02/07 13:35
Excellent, excellent software, FFT and sound analysis work Elena... the tools are great... beautifully done! The iPhone 7 microphone is well calibrated. Using the 8k FFT in high resolution work, believe you could go to a 16k no problem. Thank you very much!
Its fine...
by Hdgfgbebvbs on 2019/02/09 03:55
The spectrometer it self is great, but how your app adds it in is horrible. Every minute, it tells me to get the pro version which makes the app useless. The fristrating part is that it doesn’t even show any real ads. All it shows me is to upgrade to pro. Additionally, I don’t need or want ANY of the pro’s features. There are no ads, the accuracy is good enough and I don’t even know what FFT & RTA is! Make an option to just shush it up!
Nice App - Annoying Ad
by reviewerdan on 2020/02/23 00:25
Very nice app. Gave me exactly what I was looking for, a way to tune my small living room surround sound system. The only gripe is the completely annoying “buy me, buy me” pop up ad that covers the entire screen every 30 seconds. Make the purchase option an icon in options and stop covering up the screen. Then this app will be a perfect 5 stars.
Very Unhappy User
by Gabreael on 2019/01/13 06:55
For the pro version it cost $8.99. It might be worth it if you could hear it but you cannot hear anything I went to analyze something and listen to the play back and you can hear nothing not nothing. How can you know what it analyzed if you cannot hear it play back? It could just be sitting there rolling numbers your direction? If you use any analyzer on your PC or desktop you can hear it why can you not hear this one? So thank you for ripping me off of nine dollars!
Octave Band RTA Isn’t Working Correctly
by JesterXR on 2017/12/12 17:05
Really like the app however I noticed the frequency numbers do not match the spectrum in the RTA mode. The spectrum looks accurate but the numerical results are not. Also the feedback button doesn’t work under help so I couldn’t reach out to the developer that way to explain the issue. I think if they fix that issue this will be a great app.
Works but nags constantly
by SweetFan123 on 2019/07/24 15:11
This app works as it should but I have uninstalled it because it was so busy nagging me to buy the pro version I didn’t have time to love it enough to buy it. Additionally, it will not allow music to play on the same device that is running the app. This may be unavoidable but disappointing.
Useful tool but lacks that one thing...
by DanThrman on 2019/03/27 14:25
The complainers about the purchase ad are ridiculous. People don’t make apps without an expectation of getting paid for them. The loudest frequency tracking feature is super cool. The lack of a dB-C weighting is keeping me from buying. Level measurement for music needs it. If that ever shows up I’ll buy.
Great tool
by Rochmon on 2019/08/29 15:01
Easy to use and cost effective. I upgraded to premium and the unlocked version gives me lots of flexibility. Easy to use. I just have to leave my screen up. Lol
GREATEST Free App so far!
by ask4mask on 2018/05/26 10:08
Awesome App and It's Free! LOVE it! Have tried many other but nothing like this for Free, as it was free it pushes me to upgrade to the full version even though it's not necessary as this free version gives me everything I need! A BIG 👍
Why wait?
by James C. Bayer on 2017/10/01 16:36
I have been using this for months! Best Spectrum Analyzer I could find. Works very well. Has calibration options. What more could you need?
Missing major feature
by Adhdgj on 2020/06/09 16:39
The analyzer works fine, but what good is an analyzer without a signal generator? Tried to use a separate app, but when I switch to this app it disables output of signal generator app, so it’s really not useful to me at all. Good thing I didn’t pay for the pro version
Exhaust
by Greg Nog on 2018/08/06 02:28
I used this app for simply testing the sound level of my exhaust to check if it was too loud for my state standards, which, thanks to this app, I know it is not
Excellent app, especially for the price.
by JParker on 2018/08/10 03:25
Perhaps the best free spectrum analysis app out there. Very accurate and useful. Highly recommended if you have need for such a thing.
Very good app
by John I. Bullard on 2017/10/02 15:39
I used to use this alot for music because i always was intested in the way spectrum works and this is my dream app. Very simple yet so powerful
Very nice
by David H. Betts on 2017/09/30 15:03
Generally more stable than other similar apps, more customisation, and overall better aesthetics
Good analyzer but very user unfriendly
by Pagodafan on 2019/05/08 03:29
No manual, 4 short paragraphs in help menu provide very little help. Impossible to identify frequencies of multiple peaks because cursor line jumps to wherever it wants. No save function for each spectrum (except screen shot). Questions to developer by email remain unanswered.
Used to prove noise issue to landlord
by reinoldrr on 2020/10/14 19:36
I have sensitive hearing, my landlord does not, and I used this app to prove noise disturbance from air conditioning. The evidence saved me $3000 in moveout fees. Very grateful.
Good app
by Jeffrey G. Brown on 2017/09/29 15:36
If you need to look at your audio systems frequency response this will do the trick. The interface is simple and configurable
Nice app but...
by Ponyong888 on 2019/09/01 08:52
Nice App. But, FREE is just the same as PRO not much difference. Hope improve more so I can clearly see the difference.
Beware of Russian Malware
by bmrosen45 on 2018/12/22 01:33
I have tried the program and it appears to work well. I have not compare with professional equipment to verify its result. However I have serious reservations using a program developed in Russia. The Russian troll company has already been linked to false news during the election. Given the app requires access to your phone’s microphone it can easy be used to listen in on private conversations. Buyer beware is my point.
Difficult to evaluate
by tailsawaggin on 2018/06/13 02:37
An upgrade nag pops up every few seconds, interrupting whatever you’re doing and forcing you to deal with it. Can’t meaningfully evaluate an app under those operating conditions. Deleted after being interrupted four times in less than five minutes.
Great app
by Renee V. Dover on 2017/09/30 14:59
This app seems very good. Various options are very useful. I suggest the developers to add few more add ons in the upcoming updates
Spectrum review
by bebob zell on 2020/01/26 21:16
Very difficult to ascertain the app value as it keeps quickly jumping to please buy the pro version. That said I’ll try again to get a pink noise reading on my speakers
Could be better if not for pop up message
by fuzz6704 on 2019/03/22 16:51
Turn off the “get pro” notification that pops up all of the time! Great app otherwise but I’m deleting soon because of the pop up.
Good analyzer- don’t try it in a meeting though!
by Knyknkn on 2017/11/19 18:13
I was trying free version out running audio in a large meeting when suddenly an ad blaring loud sound effects started playing. Very embarrassing, not cool for an audio app, deleted immediately. Analyzers seemed decent
very good
by Carmen E. Barnett on 2017/10/02 15:41
Very simple, no ads. Wish there were color options, but it is the only analyzer for internally played music.
Spectrum is very good
by Rhstools on 2017/11/07 04:38
I bought a Reed meter which was very good but it was $200. This app seems better for $5
Nice app
by AimesJainchill on 2019/06/15 20:25
Shows detailed live ambient sound across frequency spectrum.
Not accurate for RTA use
by Matt Selinger on 2018/08/07 05:49
This app looks nice, but I can’t get much use out of it. Frequency data below 100 Hz is not accurate. Disappointed I paid to use the “Pro “ version. Deleting this one from my iPad.
Doesn’t work right for me
by TFozb on 2018/07/12 02:09
I gave the app 2 stars for its potential greatness but as of now the frequency value displayed at the top doesn’t change when the cursor is moved, so I can’t use it to pinpoint frequencies like I’d planned.
Not very useful
by dworsnup on 2018/04/03 19:22
This app asks you to upgrade to premium every few seconds interrupting any measurements you are trying to make. I’m not saying the utility should necessarily be free, but the free version of this utility has no actual utility.
Non stop interuption
by 12data on 2019/11/04 18:04
I get it that a premium upgrade is available. This app reminds you about every 40 seconds that a upgrade is available. Terrible
Audio Spectrum Analyzer
by DisasterIV on 2020/04/17 20:22
Do no see modes that I had before buying. I do see how to change scales, save or print a display. FFT resolution has no change. Fail to see advantage in buying it. Donald Fuelling
Annoyware - every 2 mins go pro popup
by Ignacj on 2019/05/14 21:45
How many times will you ask me to go pro before I give up on your app? Bottom line is that you lost a potential pro customer that you wanted so bad. Less is more.
Controlled limiter
by jonathanclark123456 on 2020/02/06 21:57
They purposely designed the app so it Only operates at half the accuracy as it would if you bought it.

Serious
iphone7s plus bug
by Kelotrbrbr on 2017/10/22 13:01
It doesn’t read the correct frequency on an iPhone 6S plus. It’s off by a factor of more than 10. The bar chart is accurate but the display at the top doesn’t coincide with the bar chart.
Worst scam ever
by Orazaleo on 2019/03/08 10:00
This app basically obligates you to buy the full thing or else, they give you adds every 25 seconds LITERALLY!!! Even when the phone is on airplane mode. Not fun to use, and not clear or user friendly. Definitively erasing it FOR GOOD!!
Can’t even use
by don't wanna nickname on this on 2018/10/15 04:26
Asked me three times every five minutes all ways for upgrade to pro version
Why not Pro on iOS and iPadOS?
by JML54 on 2019/10/24 20:45
All my other apps that require unlocking or add removal do that on both iPad and iPhone but not this one!
Best one
by Lesterphlatt on 2020/03/21 17:17
This is the best free analyzer I have found.
Works great!
by GoFast222 on 2019/01/13 15:03
Works great setting up church sanctuaries!!
Very nice
