Practice tips, privacy & device details

Play one clear note at a time, close to the microphone. Chords, room noise, breath attacks, vibrato and very weak fundamentals can confuse a monophonic tuner. Supported pitch range: 50–4000 Hz. The grid uses a ±5-cent tuning zone.

Pause stops the microphone. Switching tabs also stops capture. Your settings stay in this browser; pitch history is cleared when you reload. Audio is never uploaded. Recording starts only when you choose Record take. Unsaved takes stay in memory and disappear when you reload or close the app. This app uses no account or analytics.

Device details appear when practice starts.
