Great app, needs a way to export data
by Dasjing on 2019/08/20 20:42
I greatly enjoy how feature full and yet simple this app is. It runs great and seems quite accurate. One thing I think is dearly missing is a way to export the signals measured to a file (like csv). Taking pictures is great for qualitative comparison but this tool would be way more valuable if it could be quantitative.
Favorite fee app
by Elvenmimstrel on 2018/11/20 15:43
As a studio engineer who has to run live sound a few times a year, this app saves me a lot of trouble. I can ring out mics in a heartbeat and solve problems more quickly on the fly. No more sweeping for the exact frequency to notch, or for where to center the de-esser! It’s especially handy on an iPad with its larger display.
Performant and accurate.
by Not a wb on 2018/11/01 06:01
Fantastic! Apps like this are the reason we don’t need to buy a stupidly overpriced bespoke piece of gear for every little niche... unless we want to! Keep up the great work!
Great app
by unenigma on 2018/05/24 11:04
The averaging function works really well. It would be nice if I could figure out how to use an accelerometer with it
Great respect for the app developers
by Retina.doc on 2018/05/05 02:06
I use it to show my kids what music looks like in the frequency spectrum. Given how much time is required to learn and program an FFT analyzer, I am glad to support the developers efforts.
Good app
by Sir_RHT on 2018/03/25 17:02
I need to be able to concentrate analysis on extremely low frequencies, to isolate and zoom in to them.
Very nice
by Kjp123 on 2017/10/16 10:36
Very nice app. It hasn’t been updated in quite a long time but it works just fine in iOS 11. I’d like to see an update with more robust features (hi developers) maybe a spectrum analyzer too or more info on the frequency graph etc. But as it stands it works very well.
simple and easy
by everfrien on 2017/09/26 17:11
Exactly what I want
Fixed frequency range, no zoom
by Djp16746 on 2017/08/28 03:13
I was interested in 20 - 80 Hz. The range appears to be fixed at 0-21k. So the low frequency resolution is coarse and the is no peak hold for catching unstable sources.
Great app
by sethfreakingely on 2017/06/15 14:09
Super simple. An invaluable tool.
Very nice FFT
by scubnubbic on 2017/06/05 21:48
The nicest thing about this analyzer is that it has the ability to recognize the particular microphone you have plugged in to your iPhone. I use a Shure MV88 stereo mic. That means that the application is calibrated for my particular microphone! I was able to quickly equalize my sound system and it sounds much better now.
Fun and sciency
by 21stCenturyParent on 2017/06/01 02:45
If you're curious about tonals, noises, or how loud that concert really is.
Nice frequency analyzer
by FrankDRoosevelt on 2017/05/27 21:41
It's a nice, simple frequency analyzer that works well. Used it to help explain frequency and pitch to the kid. There's not a lot of bells and whistles and flashy graphics. May appeal more to a more technical (geeky) user. Would recommend.
Fantastic FFT
by Tolga Balci on 2017/04/11 08:45
Using it for a school project. Tried a few free options and there is nothing close to this app on the market. Works very well!
Works great!
by Taiden on 2017/03/30 15:14
Although I would recommend their more expensive, fully featured app. Well worth the money.
Great app!

Would be perfect if it can record a samples
Simple and accurate

I use this for music instruments and tuning forks. Does the job.
My Fave FFT App
by Cap'n Zig on 2017/01/21 03:37
It's fast/slow and window choices, and look and feel are very natural for working in the frequency domain. Watching music it just "looks" proper. The ability to decode the frequency peak to a musical note is a natural, but extremely useful feature... Three features I'd like to see? 1) Screen capture video... share the look of your favorites dynamically. 2) Capture-Process-Slomo: capture a length of audio, process the FFT, then play the video back slowly, with scrubbing, to allow transposition of complex arpeggios... 3) Transpose 2) into musical score or tablature.
Simple and Useful
by Adrian E. Braun on 2017/01/07 07:04
Nice, simple app. It does the job well. I downloaded this app to test the frequencies in songs, as I curious what are the notes sung.
Awesome App!
by Giddy33352678 on 2016/12/28 18:42
I use this at FOH a lot and really love it! Very useful and accurate!
Great App
by B9 Car Guy on 2016/08/16 15:10
This app is great for finding noise sources. I have been using it now for a good while and have been very pleased with it. It is easy enough to use and it wasn't expensive. I hope you enjoy it too!
Underrated
by Mister_Coke on 2016/05/24 20:30
I use this app when I'm performing the final tuning in car audio systems and I'm impressed with the response and resolution it has. It could be better if it supported external microphones such as ZOOM's XY and omni capsules but performs pretty reliably through the iPhone's internal microphone. And fairly accurate up against my ARC software in my recording studio studio. Well worth the money if you need a good FFT
Pretty great! Could have better decibel calibration
by b_t_naderal on 2016/05/16 03:14
This is an awesome app. Fastest and highest resolution FFT I have seen on App Store. Professional development and works well. My only request is that there be a better measurement system of overall volume ("60dB" for voice and "95dB" for concert, etc.) Oh! Also, please add split screen support for iPad!
Very cool!
by I-read on 2016/05/12 00:23
Very cool app that tells you the spl at different frequencies.
Does everything I need it to do
by megrein on 2016/04/20 14:39
Works great for real time analysis of studio monitor frequency response in a particular studio configuration, as well as tuning a PA system at a new location. Seems to be more accurate using an external mic with a flat response.
Works as your audio-minded search would hope
by CNoNews on 2016/03/05 02:26
Has all of the features you'd hope and need to do simple spectrum analysis or tuning. I've used it to troubleshoot turbulent flow in a nitrogen compressor and then tuned my piano with it later that evening. Worked perfectly.
Here is a slight improvement idea
by Ken Finn on 2016/02/07 21:09
This app works up to 20kc, the top of human hearing If the bandwidth is available, then enlarging the app to 40kc would allow you to study Ultrasound Also
I really like this app!
by luckyjayguy on 2016/01/17 03:24
I used it to diagnose a whistle sound in an air handling unit. It works quite well and I have told several other people about it. I use an iPhone 5 and when you take a screen shot and upload it to your computer, it looks very professional. The other features are very nice, too. My only suggestion is to allow zooming in on the Hertz scale.

Multiple uses
by johnbowen on 2016/01/11 12:03
I use it to track hums and vibrations throughout the home, set up my home entertainment system, adjust my bass guitar settings while playing on stage. Accurate, entertaining and informative.
Love It
by prestonesquire on 2015/12/14 22:08
I love this app; though I'm experiencing the same issue since the latest iPad iOS update. Lots of flashing and I've tried every fix I can think of and it's still not working. This app has been so useful to me in the past. Hope it gets fixed soon : (
OK - but needs work.
by Euzkadi71 on 2015/11/28 21:50
Flashes under the latest IOS 9.01 - not sure why it's doing that when it didn't under the previous IOS.
Ok, but f axis not scalable
by The Eclectic on 2015/08/31 00:04
Please make the frequency axis fully scalable. Better yet, make it so you can zoom or set to a specific range.

Great for running a sound board
by To45ty on 2015/04/26 14:50
I use it to help EQ vocals and instruments on our church's soundboard. It compares favorably with a pro sound app on a Mac with a mic. Hey, can you create sound meter app that will compensate for each phone model's mic frequency response? I have not found any accurate meter apps.
Bull cheeettt

Worst app on sound that I ever used...Don't worth the money I have spent on it... It look like a you and NOT a tool that I thought I could use for quick analysis of NVH application. You people are f...up, you don't allow any right comments that is against your apps...

by Jay-Jay 123 on 2015/02/18 06:15
Me and my friend used this app for a science fair project testing the sound waves blah blah blah. Basically it was great and very helpful so thank you and I totally suggest the app for future people interested in getting it.
Perfect
by Chip Fillingane on 2015/02/08 17:37

Best App Ever!
by Rocksalot on 2015/01/08 13:07
This app is awesome!! So much power for fine tuning your sound!! We use it at our practice and at gigs to get any and all feedback, howling etc out of the mix. You can see exactly where the problem is. Easy to use too!
Simple and Powerful
by HiMike45 on 2014/02/27 13:14
I am using it in a project to analyze and make ocarinas. It is proving very powerful at providing information on harmonic content of each of the fingerings as well as reliable at locking onto the fundamental and displaying it. Very useful also is its settings for integration time since the ocarina is a mouth blown instrument and tone changes a lot with how you blow a particular note. True one can think of lots of features you might want to see added, but for the price you get a powerful tool worth every cent of the price.
Live sound...works for me
by listener cam on 2013/12/10 12:16
Rta lite both stopped working and added adds to the last update so I went looking for a new simple app to ring monitors with...this one is doing all it needs to do. Not fancy but totally functional. Here's o hoping hey keep up with it;)
OK but a bit squirrely
by Jango Sparrow on 2013/10/22 21:28
This app seems a bit harder to navigate than others I've tried -
Perfect!
by UrGrandMother on 2013/10/06 03:01
This is a perfectly designed app! The single window interface is sooooo nice. I love that there aren't a bunch of "pop up" windows and other clutter. They keep it straight to the point - give you exactly what you need to analyze whatever sounds are around you. The "peak frequency" section is so handy and it's great that it shows you the corresponding "note value" right next to it. The pause button is great to just freeze the waveform and analyze the peaks/nulls by sliding your finger across the screen. I have used frequency analyzers in the past on my computer but there was always about 15 steps involved in getting it set up. This app is instant and there is no setup required. I WON'T be using the one on my computer anymore and I WILL be buying more apps from this company! If you want a beautifully designed and handy frequency analyzer app - this app is PERFECT! :)

Very nice, love the window function and controllable # of samples. Used it to check the vibration frequencies of a glass plate. Wish I could email or otherwise share/save the plot, though!
Really great app
by joempeterson on 2013/07/03 15:00
Simple and clear functionality. My only gripe is the - (negative) scale for SPLs
Kind of disappointing
by Robinhood88 on 2013/06/14 22:01
I think I bought the wrong app. Would have likes to be able to expand (zoom) a frequency region of interest. Would have liked to be able to zoom vertical scale as well. No help screen to explain what such things as "mixed" display means.
Fantastic app

Feature Highlights: ● FFT Size (2048 to 16384 points) ● Fast, Slow and Infinite Averaging ● Window function (Hamming, Hann, Rect) ● Peak Frequency detection ● Linear and Logarithmic scale ● Toggle between Flat, A and C weighting ● Pan to adjust visible dB range ● Draggable cursors ● iPhone X ready Audio credits: "Evening Birdsong" and "Cuckoo" by Benboncan
Great app, needs a way to export data
by Dasjing on 2019/08/20 20:42
I greatly enjoy how feature full and yet simple this app is. It runs great and seems quite accurate. One thing I think is dearly missing is a way to export the signals measured to a file (like csv). Taking pictures is great for qualitative comparison but this tool would be way more valuable if it could be quantitative.
Favorite fee app
by Elvenmimstrel on 2018/11/20 15:43
As a studio engineer who has to run live sound a few times a year, this app saves me a lot of trouble. I can ring out mics in a heartbeat and solve problems more quickly on the fly. No more sweeping for the exact frequency to notch, or for where to center the de-esser! It’s especially handy on an iPad with its larger display.
Performant and accurate.
by Not a wb on 2018/11/01 06:01
Fantastic! Apps like this are the reason we don’t need to buy a stupidly overpriced bespoke piece of gear for every little niche... unless we want to! Keep up the great work!
Great app
by unenigma on 2018/05/24 11:04
The averaging function works really well. It would be nice if I could figure out how to use an accelerometer with it
Great respect for the app developers
by Retina.doc on 2018/05/05 02:06
I use it to show my kids what music looks like in the frequency spectrum. Given how much time is required to learn and program an FFT analyzer, I am glad to support the developers efforts.
Good app
by Sir_RHT on 2018/03/25 17:02
I need to be able to concentrate analysis on extremely low frequencies, to isolate and zoom in to them.
Very nice
by Kjp123 on 2017/10/16 10:36
Very nice app. It hasn’t been updated in quite a long time but it works just fine in iOS 11. I’d like to see an update with more robust features (hi developers) maybe a spectrum analyzer too or more info on the frequency graph etc. But as it stands it works very well.
simple and easy
by everfrien on 2017/09/26 17:11
Exactly what I want
Fixed frequency range, no zoom
by Djp16746 on 2017/08/28 03:13
I was interested in 20 - 80 Hz. The range appears to be fixed at 0-21k. So the low frequency resolution is coarse and the is no peak hold for catching unstable sources.
Great app
by sethfreakingely on 2017/06/15 14:09
Super simple. An invaluable tool.
Very nice FFT
by scubnubbic on 2017/06/05 21:48
The nicest thing about this analyzer is that it has the ability to recognize the particular microphone you have plugged in to your iPhone. I use a Shure MV88 stereo mic. That means that the application is calibrated for my particular microphone! I was able to quickly equalize my sound system and it sounds much better now.
Fun and sciency
by 21stCenturyParent on 2017/06/01 02:45
If you're curious about tonals, noises, or how loud that concert really is.
Nice frequency analyzer
by FrankDRoosevelt on 2017/05/27 21:41
It's a nice, simple frequency analyzer that works well. Used it to help explain frequency and pitch to the kid. There's not a lot of bells and whistles and flashy graphics. May appeal more to a more technical (geeky) user. Would recommend.
Fantastic FFT
by Tolga Balci on 2017/04/11 08:45
Using it for a school project. Tried a few free options and there is nothing close to this app on the market. Works very well!
Works great!
by Taiden on 2017/03/30 15:14
Although I would recommend their more expensive, fully featured app. Well worth the money.
Great app!

Would be perfect if it can record a samples
Simple and accurate
by Rat8bug on 2017/01/24 16:44
I use this for music instruments and tuning forks. Does the job.
My Fave FFT App
by Cap'n Zig on 2017/01/21 03:37
It's fast/slow and window choices, and look and feel are very natural for working in the frequency domain. Watching music it just "looks" proper. The ability to decode the frequency peak to a musical note is a natural, but extremely useful feature... Three features I'd like to see? 1) Screen capture video... share the look of your favorites dynamically. 2) Capture-Process-Slomo: capture a length of audio, process the FFT, then play the video back slowly, with scrubbing, to allow transposition of complex arpeggios... 3) Transpose 2) into musical score or tablature.
Simple and Useful
by Adrian E. Braun on 2017/01/07 07:04
Nice, simple app. It does the job well. I downloaded this app to test the frequencies in songs, as I curious what are the notes sung.
Awesome App!
by Giddy33352678 on 2016/12/28 18:42
I use this at FOH a lot and really love it! Very useful and accurate!
Great App
by B9 Car Guy on 2016/08/16 15:10
This app is great for finding noise sources. I have been using it now for a good while and have been very pleased with it. It is easy enough to use and it wasn't expensive. I hope you enjoy it too!
Underrated
by Mister_Coke on 2016/05/24 20:30
I use this app when I'm performing the final tuning in car audio systems and I'm impressed with the response and resolution it has. It could be better if it supported external microphones such as ZOOM's XY and omni capsules but performs pretty reliably through the iPhone's internal microphone. And fairly accurate up against my ARC software in my recording studio studio. Well worth the money if you need a good FFT
Pretty great! Could have better decibel calibration
by b_t_naderal on 2016/05/16 03:14
This is an awesome app. Fastest and highest resolution FFT I have seen on App Store. Professional development and works well. My only request is that there be a better measurement system of overall volume ("60dB" for voice and "95dB" for concert, etc.) Oh! Also, please add split screen support for iPad!
Very cool!
by I-read on 2016/05/12 00:23
Very cool app that tells you the spl at different frequencies.
Does everything I need it to do
by megrein on 2016/04/20 14:39
Works great for real time analysis of studio monitor frequency response in a particular studio configuration, as well as tuning a PA system at a new location. Seems to be more accurate using an external mic with a flat response.
Works as your audio-minded search would hope
by CNoNews on 2016/03/05 02:26
Has all of the features you'd hope and need to do simple spectrum analysis or tuning. I've used it to troubleshoot turbulent flow in a nitrogen compressor and then tuned my piano with it later that evening. Worked perfectly.
Here is a slight improvement idea
by Ken Finn on 2016/02/07 21:09
This app works up to 20kc, the top of human hearing If the bandwidth is available, then enlarging the app to 40kc would allow you to study Ultrasound Also
I really like this app!
by luckyjayguy on 2016/01/17 03:24
I used it to diagnose a whistle sound in an air handling unit. It works quite well and I have told several other people about it. I use an iPhone 5 and when you take a screen shot and upload it to your computer, it looks very professional. The other features are very nice, too. My only suggestion is to allow zooming in on the Hertz scale.

Multiple uses
by johnbowen on 2016/01/11 12:03
I use it to track hums and vibrations throughout the home, set up my home entertainment system, adjust my bass guitar settings while playing on stage. Accurate, entertaining and informative.
Love It
by prestonesquire on 2015/12/14 22:08
I love this app; though I'm experiencing the same issue since the latest iPad iOS update. Lots of flashing and I've tried every fix I can think of and it's still not working. This app has been so useful to me in the past. Hope it gets fixed soon : (
OK - but needs work.
by Euzkadi71 on 2015/11/28 21:50
Flashes under the latest IOS 9.01 - not sure why it's doing that when it didn't under the previous IOS.
Ok, but f axis not scalable
by The Eclectic on 2015/08/31 00:04
Please make the frequency axis fully scalable. Better yet, make it so you can zoom or set to a specific range.

Great for running a sound board
by To45ty on 2015/04/26 14:50
I use it to help EQ vocals and instruments on our church's soundboard. It compares favorably with a pro sound app on a Mac with a mic. Hey, can you create sound meter app that will compensate for each phone model's mic frequency response? I have not found any accurate meter apps.
Bull cheeettt
by Bull_cheeettt on 2015/04/24 02:17

Displays a clear and accurate the frequency present in an environment. Hats off to the developers A+ app.
SCIENCE FAIR
by Jay-Jay 123 on 2015/02/18 06:15
Me and my friend used this app for a science fair project testing the sound waves blah blah blah. Basically it was great and very helpful so thank you and I totally suggest the app for future people interested in getting it.
Perfect
by Chip Fillingane on 2015/02/08 17:37

Best App Ever!
by Rocksalot on 2015/01/08 13:07
This app is awesome!! So much power for fine tuning your sound!! We use it at our practice and at gigs to get any and all feedback, howling etc out of the mix. You can see exactly where the problem is. Easy to use too!
Simple and Powerful
by HiMike45 on 2014/02/27 13:14
I am using it in a project to analyze and make ocarinas. It is proving very powerful at providing information on harmonic content of each of the fingerings as well as reliable at locking onto the fundamental and displaying it. Very useful also is its settings for integration time since the ocarina is a mouth blown instrument and tone changes a lot with how you blow a particular note. True one can think of lots of features you might want to see added, but for the price you get a powerful tool worth every cent of the price.
Live sound...works for me
by listener cam on 2013/12/10 12:16
Rta lite both stopped working and added adds to the last update so I went looking for a new simple app to ring monitors with...this one is doing all it needs to do. Not fancy but totally functional. Here's o hoping hey keep up with it;)
OK but a bit squirrely
by Jango Sparrow on 2013/10/22 21:28
This app seems a bit harder to navigate than others I've tried -
Perfect!
by UrGrandMother on 2013/10/06 03:01
This is a perfectly designed app! The single window interface is sooooo nice. I love that there aren't a bunch of "pop up" windows and other clutter. They keep it straight to the point - give you exactly what you need to analyze whatever sounds are around you. The "peak frequency" section is so handy and it's great that it shows you the corresponding "note value" right next to it. The pause button is great to just freeze the waveform and analyze the peaks/nulls by sliding your finger across the screen. I have used frequency analyzers in the past on my computer but there was always about 15 steps involved in getting it set up. This app is instant and there is no setup required. I WON'T be using the one on my computer anymore and I WILL be buying more apps from this company! If you want a beautifully designed and handy frequency analyzer app - this app is PERFECT! :)

Very nice, love the window function and controllable # of samples. Used it to check the vibration frequencies of a glass plate. Wish I could email or otherwise share/save the plot, though!
Really great app
by joempeterson on 2013/07/03 15:00
Simple and clear functionality. My only gripe is the - (negative) scale for SPLs
Kind of disappointing
by Robinhood88 on 2013/06/14 22:01
I think I bought the wrong app. Would have likes to be able to expand (zoom) a frequency region of interest. Would have liked to be able to zoom vertical scale as well. No help screen to explain what such things as "mixed" display means.
Fantastic app
