TempoTuner is a free online rhythm practice tool for singers and musicians. Tap anywhere on the screen to the beat while singing, drumming or playing an instrument. TempoTuner measures your tempo in BPM on every tap and draws it on a live graph, so you can see exactly where you rushed or slowed down. It works in any browser, on any phone, with no install and no account.
Set a target BPM to get a dashed target line on the tempo graph and unlock the metronome. Practice with the metronome clicking, or turn it off after a few beats and see how steady you stay on your own. Keeping steady time is one of the hardest skills for singers and musicians practicing without a backing track — TempoTuner is a beat keeper and tempo consistency checker that shows your drift instead of just telling you a number.
Record your voice while you tap, then play it back: a playhead moves along the tempo graph so you can hear the exact moment your timing drifted. Recordings stay on your device and are never uploaded.
Every day there is one well-known song. Sing it in your head and tap its main beat from memory — the steady pulse you would clap along to, not every word — and see how close you got to the song's real BPM. Unsure what to tap? The demo plays Twinkle Twinkle Little Star and pulses exactly where the taps go. Build a streak, share your score as an image with your tempo graph, and join the daily leaderboard with just a nickname — it's ear training disguised as a game.
TempoTuner works as an app on your phone: open your browser menu and choose Add to Home Screen (or Install). It launches full-screen from its own icon and works offline.
Taps and recordings never leave your device. Visits are counted anonymously with GoatCounter — no cookies, no personal data, so there is no consent banner. If you join the daily leaderboard, your chosen nickname and daily scores are stored on our server (no email, no account); everything else stays local.
