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).
Good, simple app
Best thing of its kind, gets the job done
Changed ad method: ads on exiting app only.
Audio Tone Generator 20 - 20 000 Hz. Perfect for testing or pranking!
