DrainTone: Speaker Cleaner

Wet speaker sounding muffled? Run a quick low-frequency water eject cycle, then check the sound in seconds.

DrainTone is a simple sound-based utility designed to help eject trapped water from your iPhone speaker after water exposure. It plays low-frequency tones through the speaker and then lets you run a short speaker test to check whether the sound seems clearer.

Quick Clean is available for free and runs a 30-second water eject cycle. It is designed for fast use after light water exposure.

DrainTone Pro unlocks longer fixed cleaning cycles:

• Deep Clean: a 60-second multi-tone water eject cycle.
• Heavy Water: a 90-second longer cycle for stubborn trapped water.
