Voice-first pitch detection
Tone Finder listens and shows your note in real time, with gentle feedback on whether you're a little high, a little low, or right on. No jargon, no account — and your voice never leaves your device.

Sing a sustained note and watch the nearest note update in real time as you hold it.
“A little high” or “right on” — clear guidance that helps you adjust with confidence.
Pick a note to aim for and compare your live pitch against it as you sing.
Short sessions and a streak keep you coming back — progress without pressure.
Microphone audio is analyzed locally on your iPhone for privacy and instant response.
Smoothing tuned for the human voice keeps feedback calm instead of jittery.
Privacy first. Tone Finder needs no account and doesn't upload your voice. The microphone is used only while you're actively listening.
