Got water stuck in your phone speaker? Sonic Water Eject is the ultimate speaker cleaner tool that uses powerful sound frequencies to push water out of your iPhone and AirPods in seconds. No rice, no waiting, no expensive repairs - just pure acoustic technology that really works. HOW DOES IT WORK? When water gets trapped inside your device speakers, it muffles sound and can cause permanent damage if left untreated. Our app generates precise low-frequency Hz tones (150-180 Hz range) combined with haptic vibrations to create acoustic pressure waves. These waves physically push water droplets out through speaker grills, restoring clear audio quality fast. This is the same technology used by Apple Watch to eject water - now available for your iPhone and AirPods. The process is completely safe, requires no special tools, and works on all iPhone models. SMART CLEANING MODES Different situations call for different solutions. Choose the perfect mode for your needs: - Normal Mode - Balanced 15-second cleaning cycle for everyday water exposure. Perfect after rain or light splashes. - Gentle Mode - Soft frequency output for delicate cleaning. Ideal when you suspect minor moisture but want to be extra careful. - Intensive Mode - Maximum acoustic power for stubborn water that won't budge. Use after pool drops, beach accidents, or heavy rain exposure. - AirPods Clean - Specially calibrated frequencies optimized for the tiny mesh speakers in your AirPods and AirPods Pro. Removes water and debris safely. - Case Clean - Targeted cleaning mode for your AirPods charging case speaker. Keep your entire audio ecosystem in top condition. SPEAKER TEST & DIAGNOSTICS Not sure if your speakers need cleaning? Our comprehensive test suite helps you diagnose audio problems before and after cleaning: - Bottom Speaker Test -Check your main loudspeaker output quality - Top Speaker / Earpiece Test - Verify call audio clarity - Left and Right Channel Test - Ensure perfect stereo balance - Real-time Playback - Listen to actual audio output and judge quality yourself Unlike other apps with fake meters and simulated results, we give you real sound output so you can hear the difference with your own ears. Test before cleaning, clean, then test again to confirm improvement. TRACK YOUR CLEANING HISTORY Premium users get access to detailed analytics and usage statistics: - Session History - Complete log of every cleaning session with timestamps - Visual Charts - Beautiful weekly activity graphs showing your maintenance habits - Device Tracking - Separate statistics for iPhone speaker, AirPods, and charging case - Streak Counter - Monitor consecutive days of device care - Mode Analytics - Discover which cleaning mode you use most often Perfect for users who want to maintain a regular device care routine and track their progress over time.
