Water in your speaker?

Water eject, deep clean, dust removal and speaker testing — in one app.

Grille plays engineered low-frequency tones through your phone's speaker. The sound pressure vibrates the speaker membrane, which can help push trapped water droplets and loose dust out of the grille.

What's inside

Routine	What it does
Water Eject	The classic pass centred on 165 Hz — the same range a smartwatch uses for the same job
Deep Clean	A wide sweep with multiple passes, for speakers still muffled after one round
Dust Remover	Pulsed mid and high tones that shake loose dust and pocket lint free
Earpiece Care	A quieter, gentler routine tuned for the small speaker you hold to your ear
Speaker Test	A clean reference tone through the left, right or both channels
Custom Frequency	Any tone from 20 Hz to 20 kHz, with four waveforms and a live oscilloscope

Before you use it

Never use Grille with headphones on. The app blocks playback when it detects them.
Keep the device away from ears — yours, other people's, and your pets'.
Grille can help clear a speaker grille. It cannot repair a water-damaged device. If your phone has been submerged, follow the manufacturer's guidance and seek professional service.
