Phone Speaker Test - Tonewash

Tonewash is a phone speaker test and speaker cleaner in one app. Run a speaker test on the left, right and earpiece speakers with clear tones, and when your phone gets wet, play a low tone with vibration so water drops in the speaker grille shake loose. Then measure the sound before and after with the microphone, so you see the result in numbers instead of a progress bar.

LEFT, RIGHT AND EARPIECE CHECK
• A quick phone speaker test: a 1 kHz tone on the left, the right or both sides
• Earpiece speaker test: check the speaker you hold to your ear on its own
• On phones with one speaker, Left and Right play from the same place
• A sweep from 100 Hz to 10 kHz to hear buzzing or rattling
• Set a manual tone from 100 to 500 Hz, add vibration and pick 30, 60 or 90 seconds

HOW THE WATER EJECT WORKS
1. Unplug earbuds, wipe the phone dry and hold the speaker facing down.
2. Optional: tap "Measure before you start". Three short test tones (500 Hz, 1 kHz and 3 kHz) give you a before number.
3. Tap Start. For 60 seconds the tone sweeps from 140 to 300 Hz and holds at 165 Hz, with vibration.
4. Measure again and see before and after side by side.

AN HONEST RESULT
• Clearer: the speaker plays at least 3 dB louder than before, measured the same way.
• No change measured: drops can take more than one cycle. Run it again, up to 3 cycles in a row.
• Quieter: stop and let the phone dry.
The numbers are relative levels from your phone's microphone, not a lab measurement, and the ring shows the seconds left, not a made-up percentage.

SPEAKER CLEANER FOR BOTH SPEAKERS
• Bottom speaker or earpiece, so it works as an earpiece cleaner too
• Tone + vibrate, tone only or vibrate only
• Volume goes to maximum only when you tap "Set to max", and your old volume comes back after the cycle
• Start is turned off while earbuds are connected, because the tone is loud

WHEN IT CAN'T HELP
Tonewash can help remove water from speaker grilles after rain, a splash or washing your hands. It can't remove dust or lint (use a soft, dry brush), dry a phone that was under water for a long time, or help a speaker that already crackled before it got wet. Don't charge the phone while the port is wet.

PRIVACY
No account. The microphone is used for about 4 seconds, only after you tap Measure. Nothing is recorded or uploaded; only the three numbers are kept on your phone.

ADS
No ads before your first cycle and never while the tone is playing.
