Dropped your phone in water? Sound muffled after rain, a pool or the sink? Water Eject plays a powerful 165 Hz low-frequency sweep — the same principle the Apple Watch uses — to vibrate your speaker and physically push the water out. YOUR FIRST CLEAN IS FREE Try it before any payment. Watch the droplets appear, play the test tone, hear the difference. HOW IT WORKS The tone makes your speaker diaphragm vibrate hard enough to eject trapped water droplets. Run 2–4 cycles for the best result, then confirm with the built-in Speaker Check. CLEANING MODES • Water Eject — 100–250 Hz sweep around the proven 165 Hz tone • Dust Clean — higher-frequency sweep that shakes loose light dust and lint • Earpiece — routes the tone to the top call speaker • Deep Clean (Premium) — four-stage purge for stubborn water, ending with an experimental resonance burst • Three intensity levels: Light, Normal, Intensive FREE TOOLBOX • Decibel Meter — live loudness readings (analyzed on-device, never recorded) • Tone Generator — precise 20 Hz – 20 kHz frequency generator with 4 waveforms • Speaker Test — left/right channels, bass sweep, treble and full-range sweep • Speaker Check — before/after test tone so you know it actually worked • Haptic Shake — the phone pulses with the tone so you can feel each cycle (feedback, not the mechanism) HONEST BY DESIGN No ads. No account. No data collected. We tell you upfront what this can fix (water and dust in the speaker) and what it can't (liquid in the charging port or inside the phone). Bursts are capped with cool-down gaps to protect your speaker. PREMIUM Unlimited cleans with a 7-day free trial, or a one-time 10 Years purchase.
