🔊 SPEAKER CLEANER — 10-DAY ROUTINE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The only speaker water remover app built around a scientifically
progressive 10-day cleaning programme. Each day uses a different
frequency pattern — sine waves, pulsing tones, and logarithmic sweeps —
that gradually increase in intensity to dislodge moisture and debris
without stressing your speaker membrane.
✔ All 10 days unlocked — complete the full routine in one sitting or
spread it across days, your choice
✔ Frequencies from 50 Hz to 450 Hz targeting the exact resonance range
of mobile phone speakers
✔ Progressive amplitude ramp: Day 1 is gentle, Day 10 is maximum power
✔ Each session tracks live progress with a real-time timer
🚀 QUICK BOOST
Need instant water ejection? Quick Boost fires a 45-second
high-intensity sweep from 100 Hz to 350 Hz — the fastest way to
clear a muffled speaker after a sudden splash.
