Speaker Cleaner & Sound Test

Speaker Cleaner plays a low 165 Hz tone to push liquid water out of your iPhone speaker. It measures your speaker's sound level with the microphone before and after each clean, so you can see whether anything changed. Cleaning - Water clean: 30 seconds of 165 Hz tone - Deep clean: a 60-second sweep from 165 Hz to 2 kHz, for water that stays put - Sand clean: 45 seconds of bass pulses and mid tones with vibration, to try to shake loose grains out - Before and after measurement in dB, with your microphone - Cleaning history and a share card - Optional cleaning reminder every week, every 2 weeks or every month, at a time you choose Sound tools - Tone generator: 20 Hz to 20 kHz, with sine, square, triangle and saw waves - dB meter: a live estimate of the sound level around you, with the lowest, average and highest reading - Stereo test: play the top speaker, the bottom speaker or both What it can't do Speaker Cleaner moves liquid water. Sand clean can't remove dirt, lint or dried residue that is stuck in the grille, and the app doesn't change your phone's volume. The dB meter uses the iPhone microphone and gives an estimate, not a calibrated reading. Privacy Microphone audio stays on your phone.
