Water or dust making your speaker sound muffled? Speaker Cleaner is a water and dust cleaner for your iPhone speaker. Tuned low-frequency sound waves and vibration help push water, dust and lint out of the speaker grille, so your sound can come through clearly again. It also gives you four handy audio and motion tools: a tone generator, a dB meter, a GPS speed meter and a speaker test, all in one clean, simple app. WATER & DUST CLEANER • Helps with both water and dust: run a quick clean after a splash, or a Deep clean for dust and lint • Four-stage cleaning built around the classic 165 Hz tone, with sweeps and pulses that shake water loose • Vibration helps loosen dust, lint and debris in the speaker grille • Quick 15-second clean, free and unlimited • 30-second, 60-second and Deep clean with vibration for stubborn water and dust (Pro) • Live progress, frequency readout and step-by-step status • Reminds you to turn the volume up and to disconnect headphones or Bluetooth speakers TONE GENERATOR • Play any frequency from 10 Hz to 20 kHz • Sine, square, triangle and saw waves • Volume and left/right balance • Fine-tune 1 Hz at a time, or pick a preset: 165 Hz water eject, bass, A4 tuning, 1 kHz test, high and mosquito tones DB METER • Live sound level around you, plus min, average and max • Level history graph and the dominant frequency in Hz • Clear labels from "Quiet" to "Dangerous", so you know when to protect your ears SPEED METER • GPS speed while you walk, run, cycle or ride as a passenger • Max and average speed, distance, time, altitude and heading • GPS signal quality at a glance • km/h, mph, m/s or knots SPEAKER TEST • Test the top and bottom speakers separately • Stereo test that switches between speakers • Bass mode for low notes • Full 20 Hz to 20 kHz frequency sweep (Pro) PRIVATE BY DESIGN No account, no ads, no tracking. The microphone is used only while the dB meter runs, and your location only while the speed meter runs. Everything is processed live on your iPhone. Nothing is recorded, stored or sent anywhere. HOW TO GET THE BEST RESULTS 1. Turn the volume all the way up and remove any case that covers the speaker. 2. Hold the phone with the speaker facing down so water can drip out. 3. Start a clean. Repeat it, or use Deep clean, if the sound is still muffled. 4. For dust, run Deep clean, then gently brush the grille with a soft, dry brush. FREE AND PRO Free: unlimited Quick clean and the speaker test, plus 3 free sessions a day of the tone generator and dB meter (1 minute each) and the speed meter (5 minutes each). Speaker Cleaner Pro unlocks the 30-second, 60-second and Deep clean modes and the frequency sweep, and removes all daily limits. Pro is an auto-renewing weekly or yearly subscription. Payment is charged to your Apple Account when you confirm the purchase. The subscription renews automatically unless it is canceled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the period ends. You can manage or cancel your subscription anytime in your Apple Account settings. Please note: results depend on your device and how much water got in. Speaker Cleaner cannot repair hardware damage, and dB readings are estimates, not calibrated measurements. Keep the phone away from your ears while tones play, and never use the speed meter while driving.
