Sonicx clean your phone

A simple and user-friendly app that lets you play sounds at specific frequencies.

Bonus Feature: Easily clean your phone's speakers from water with just one button press—no complex settings required!

Noise Level Measurement: The app also measures current noise levels. It needs microphone access for this feature. If you declined access initially, go to Settings > Privacy > Microphone and enable access for the sound level meter to work correctly.
