About

Water Eject

Features
Read full description

Dropped your phone in water, got caught in the rain, or does your speaker just sound muffled? Water Eject plays specially shaped low-frequency tones that vibrate the speaker membrane and push water droplets out of the grille — the same trick smartwatches use after swimming. WATER EJECT • One-tap automatic sequence (about a minute): pulsed bursts and sweeps tuned to the speaker's resonance • Works on the bottom loudspeaker and on the earpiece at the top of the phone • Synced vibration helps shake droplets loose DEEP CLEAN • A physically different signal that agitates instead of pushes — wobbled bursts, chirps and impulse knocks shake out dust and debris • Clean the phone speaker, the earpiece, or your headphones • Interactive step-by-step guide, cleaning history and optional reminders every two weeks MANUAL MODE • Pick the exact tone and the output — loudspeaker, earpiece or headphones • Live visual feedback synced to the sound SAFE BY DESIGN • All tones stay in a low, hearing-safe range • A clear warning before anything plays through headphones PRIVATE • No account, no ads, no tracking — everything stays on your device If your speaker sounds muffled after getting wet: run Water Eject, let the phone dry, and repeat if needed.
