Was pretty great until ads were installed. Like the wifi one I have older versions.
It works great I tested it and it great
App is too good. I would just like to have additional feature-to record the waveform and view it again with zoom in out function..
very inaccurate. try to 'sing' a 400hz tone.... updates are slow. no reference at all to measure anything. no
The only problems I had is that it doesn't work on Android 7.0
Very accurate(because it can be calibrated).
Changed ad method: ads on exiting app only.
