Comments on Smart AMP Pro - SoundAmplifier for Android

★★★★☆ Conner P Twilhec · Jun 10, 2021

Deserves 5 stars really, it is a great app however each time I went to another app or shut my screen off the app stopped working. Also, the ear test instructions were a tad difficult to figure out.

Pay to use apps are my least liking of them all.
