Doesn't work on modern OS
App hasn't been updated in so long it doesn't work either on iOS 16 iPhone or on a Mac.
Do not buy unless you have a very old and non-updated phone/tablet for some reason.

Does not work
Crashes on opening
Doesn’t work at all
Opened the app and as soon you you tap a button in the app to do something, it crashes
Simply doesn’t work.
The app in not responding to any audio signal.
Not to built in mic, not to any external mic.
Mutes any audio playing on a device.
Completely useless, waste of money.

Dosent work
App did not work, no help, not responding at all.
I dont recommend it.
I dont recommend it.
Totally useless
Does not ask to access the microphone. Therefore does nothing.
The beginnings of a great app
Useful app to take a closer look at a sound. I really like the spectrogram mode where you can see the evolution of peaks in the spectrum over time. Unfortunately the frequency scale is completely wrong - just feed it a pure sine wave of known frequency, and the peak appears at the wrong frequency (about 10x too low)
Two years after I first reviewed this there is still lots of missing functionality: on screen stop/start, screen capture (without "screen shot"), ability to zoom / change scales, ability to add a cursor to read detailed information.
Right now this is no more than a toy app, OK for exploring the sounds around you but no scientific instrument...

It's a shame this app is for sale.
The spectrograph returns data that is off by a factor of 10. Play it a 440hz "A" and it reads out a bold line around 40hz. I can't read the exact measurement because the scale is useless.
The RTA section is filled with noise, it looks like the FFT was not windowed at all, and the scale is linear. Annoying and useless.
The oscilloscope seems cool, but there are not enough user controls to make it anything more than a fun waveform display. Complete waste.
Please make the tweaks and give the users what they paid for.

Mr.
It would ha been better if the x axis is adjustable for few seconds and also the ability to pause the plot.
Useless
You can't analyze anything with this app. There is no scales or units. It looks like in development mode and shouldn't cost any money yet.
garbage app
Used it with three 128hz tuning forks. First there is no actual reading. It gives a spectrum with no ability to analyze. The peaks were way off somewhere in the 10-20 range instead of 128hz. Essentially useless. Apple should remove from store ASAP.
