Speaker Cleaner - Sound Fix
Remove water and dust from your speakers, test their sound, and fine-tune frequencies — all in one simple app.
Speaker Cleaner offers a free tier, and may also offer one or more optional paid Subscription plans (such as a Weekly or Monthly plan) to unlock extra features. Exactly which plans are active and what's included in the free tier is always shown on the app's own purchase screen before you buy anything. See how billing works for any plan in our Terms of Use.
Remove water
A guided, multi-step cleaning cycle first detects your earpiece, top and bottom speakers, then sends targeted low-frequency sound pulses designed to physically push trapped water out of the openings, and finishes with a full cleaning summary — pick a 30, 45 or 60 second cycle depending on how much water got in.
Clear dust
The same cleaning cycle also helps loosen dust and pocket lint that quietly mutes your speaker over time — no separate mode to find, just run it the same way.
Speaker & mic test
Play a test tone through your earpiece and main speaker separately, then record and instantly play back your own voice to check the microphone — so you know exactly which part needs attention, not just that "something" sounds off.
Tone generator
Drag to any frequency from 20 Hz to 20 kHz, or jump to a handy preset (100 Hz, 440 Hz, 1 kHz, 10 kHz), to test your speakers across the full audible range or just explore sound.
Weekly clean reminder
An optional local notification, once a week, nudging you to give your speakers a clean — on by default, one tap to turn off in Settings, no account or server involved in scheduling it.
Common situations Speaker Cleaner helps with
Sound muffled after the rain
Caught in the rain, dropped your phone in a puddle, or just walked in wet weather — a quick cleaning cycle is usually enough to clear it up.
Dropped it by the pool or shower
A splash near the pool, a shower mishap, or a spilled drink — the same cleaning cycle works regardless of how the water got in there.
Buying or selling a used iPhone
Run the Speaker & mic test before you buy or sell — it takes under a minute to confirm every speaker and the microphone actually work.
