Microphone Cleaner

Most cleaning apps play a tone and tell you it worked. This one measures. Microphone Cleaner runs a real test on your phone. It plays known tones through your speaker, listens to them with your own microphone, and turns what it hears into numbers you can read: background noise, captured level, high frequency clarity, distortion and stereo balance. Then it explains in plain words what may be wrong and what to try next. WHAT YOU CAN DO Quick test One tap and about fifteen seconds. You get a microphone health score out of 100, a written verdict, and a ranked list of things to try. Every result is saved so you can compare against it later. Guided microphone clean Record a short before clip, run the cleaning tone, then record an after clip. The app measures both and shows you the difference. If nothing changed, it says so. Speaker clean with proof It measures your speaker, runs the cleaning tone, then measures again. You see whether the port actually cleared instead of taking an app's word for it. Live microphone meter Watch your input level in real time, read the noise floor of the room you are in, and see whether your phone gives apps one channel or two. Recording test Record a clip and listen back. Your ears catch muffling that numbers can miss. Clips stay on your phone so you can compare them later. Speaker test Check the earpiece and the loudspeaker before blaming the microphone. Tone lab Play any frequency from 50 Hz to 8 kHz at any volume, for testing a speaker or a microphone at one exact pitch. Device information What your phone reports about its own microphones, sample rates and audio hardware. Safe cleaning guide What actually works, what damages phones, and when to stop and see a technician. BEING HONEST WITH YOU Sound cannot physically clean your phone. A loud low tone makes the speaker push air hard, and that vibration can shake a water droplet or a loose speck of dust out of a port. That is worth trying and it does help. It cannot pull out packed lint or sticky grime, it cannot reach anything lodged deep inside, and it cannot repair a microphone that is damaged. That is exactly why this app measures. When the readings do not move, it tells you plainly and points you toward gentle manual cleaning or a repair shop, instead of pretending the job is done. PRIVACY This app has no internet permission at all. Not restricted, not optional, simply not in the app. Nothing can leave your phone even by accident. Test recordings are written to private storage and you can delete any of them whenever you like. The only permission it asks for is Microphone, because measuring a microphone means listening to it. NO ACCOUNT, NO PAYWALL No sign in. No subscription. Nothing held back behind a purchase. Every test, every measurement and every tool is there from the moment you install it, and it all works fully offline.
