About

BPM Tapper reads tempo from your taps: hit the button in time with a beat and it shows the beats-per-minute, smoothing over your last several taps. Pause for two seconds to start fresh.

How it works

Each tap records a performance.now() timestamp; BPM is 60000 ÷ average interval over a rolling window of the last eight taps. Entirely client-side, nothing stored.
