Plays a 165 Hz tone for 30 seconds. Turn the volume up, keep the speaker facing down and take headphones off. The app adds pulses, sweeps and more modes.
When to use it
- Your iPhone sounds muffled, quiet or distorted after getting wet
- Calls are hard to hear because the earpiece is clogged
- Your speaker grille has dust or lint in it
- AirPods or a Bluetooth speaker sound dull after moisture
How it works
At about 165 Hz the speaker membrane moves the most and pumps air through the grille. Short pulses break the surface tension that holds droplets in the mesh, and slow frequency sweeps shake loose whatever is left. It is the same idea as Water Lock on Apple Watch.
Cleaning modes
- Water: eject water after rain, a splash or a shower
- Dust: shake loose particles from the speaker grille
- Deep: a longer cycle for heavily muffled sound
- Earpiece: its own frequency band for the top speaker you hear calls through
- AirPods and Bluetooth speakers: clean external devices too
Speaker check: see the result
Measure your speaker with the microphone before and after a cleaning and see how many dB louder it got.

Good to know
Sound can clear water and loose dust from the speaker grille. It can't repair hardware damage, and it can't dry the inside of a phone. If your phone was fully submerged, turn it off and let it dry first. If the sound stays muffled after a few cycles, contact Apple Support.
