Mic Tune : Real-time Autotune

I built this app for my kid brother — a tour guide who couldn't afford a proper microphone. It's for anyone who wants to sing karaoke without owning a mic, for small-time MCs, and for tour guides still waiting on their first tip. MicTune turns your iPhone into a live microphone with real-time pitch correction. Speak or sing into the phone and your voice comes out of a Bluetooth speaker, an AirPlay device or wired headphones — instantly, with no setup and no account. Use it as a portable PA for a classroom, a small event, a tour group, a market stall or a family gathering. Anywhere you have a speaker, you have a megaphone. LIVE MICROPHONE * Tap Start and your voice is amplified through the connected speaker * Adjustable gain with a live level meter, so you can hear how loud you really are * Choose the output: Bluetooth speaker, AirPlay, wired headphones or the built-in speaker AUTO-TUNE * Real-time pitch correction — your voice snaps to the nearest note as you sing * Choose a scale: Chromatic, C Major, A Minor or Custom * Adjust correction strength from subtle to full hard-tune * Pitch meter shows your detected note and target note live SOUND CONTROL * 10-band equaliser with ready-made presets for speech, music and outdoor use * Voice processing that suppresses echo and howling feedback * Everything applies live — adjust while you talk and hear the result immediately RECORD THE SESSION * Record what you say and keep it on the phone * Play back with a scrubber, rename any recording, share it with the system share sheet * Recordings stay in the app until you delete them KEEPS RUNNING * Audio continues when the screen locks or you switch apps * Lock-screen and Control Centre controls PRIVACY * Your voice is never sent anywhere. Nothing is uploaded, nothing is transcribed. * Recordings stay on your device * No account, no sign-in TWO LANGUAGES * English and Vietnamese GOOD TO KNOW * Bluetooth adds a short delay between speaking and the sound coming out — normal for every Bluetooth speaker. A wired connection gives the lowest latency. * Keep the phone away from the speaker to avoid feedback. Lower the gain if you hear howling. * Auto-Tune works best with singing. For speech, keep correction strength low or off. Free, with ads.
