Got water stuck in your Apple Watch speaker? SonicClear uses a precision-tuned 165 Hz sine wave — the resonant frequency of the Apple Watch speaker grill — to physically push water out. Combined with continuous haptic pulses, it's the fastest way to restore crystal-clear sound. HOW IT WORKS • A 165 Hz tone plays at maximum volume, creating strong air displacement inside the speaker chamber • The frequency matches the speaker grill's resonant frequency for maximum vibration amplitude • Haptic pulses add physical vibration to dislodge water trapped in crevices FEATURES • One-tap water ejection — just press START PURGE • Real-time visual feedback with animated resonance rings • Elapsed time tracking to monitor your purge cycle • Built-in "How It Works" guide with step-by-step instructions • Optimized 165 Hz frequency for Apple Watch speakers • Combined acoustic + haptic water removal • Premium, minimal design — no ads, no subscriptions INSTRUCTIONS Hold your watch with the speaker facing down Tap START PURGE Wait 15–30 seconds Gently tap your watch on your palm to shake out remaining water Repeat if needed TIPS • Turn the Digital Crown up to maximize volume before starting • Run multiple purge cycles for stubborn water • Works best immediately after water exposure Designed exclusively for Apple Watch. No iPhone required.
