About

Grille

Water in your speaker? Grille plays engineered low-frequency tones through your phone's speaker. The sound pressure vibrates the speaker membrane, which helps push trapped water droplets and loose dust out of the grille. No account. No setup. Take the case off, point the speaker down, press start. CLEANING ROUTINES • 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 a speaker still muffled after one round • Dust Remover — pulsed mid and high tones that shake loose dust and pocket lint out of the grille • Earpiece Care — a quieter, gentler routine tuned for the small speaker you hold against your ear SOUND TOOLS • Speaker Test — play a clean reference tone through the left channel, the right, or both, and hear for yourself whether one side is quieter or crackly • Custom Frequency — dial in any tone from 20 Hz to 20 kHz, choose sine, triangle, square or saw, and watch it move on a live oscilloscope BUILT WITH CARE • Gentle, Standard and Deep change how long a routine runs, never how loud it gets — no sudden volume jumps • Grille raises your volume for you, then puts it back exactly where it was • Haptics pulse in time with the tone, adding mechanical agitation on top of the sound • Playback is blocked while headphones are connected, because at this volume that matters • Dark and light themes, in English, Turkish, Azerbaijani and Russian WHAT GRILLE IS NOT Grille can help clear a speaker grille. It cannot repair a water-damaged device, and results vary by phone model and by how long liquid has been sitting there. If your device has been submerged, follow the manufacturer's guidance and seek professional service. Never use Grille while wearing headphones or earphones. Keep the phone away from ears — yours, other people's, and your pets'.
