How many times should I tap?

Four or five taps is enough for a stable reading; keep tapping and it keeps refining. A pause of about two seconds resets the count.

Is anything uploaded?

No, the tempo tapper runs entirely in your browser and uses only your taps. There's no file, no upload and no sign-up.

Why is the BPM double or half what I expected?

Tempo is ambiguous by an octave: 75 and 150 BPM share the same pulse. Tap the beat you'd count by hand and use that figure.

How a tempo tapper works

Tap a key or the button in time with the beat, on each downbeat is easiest. The tool measures the gaps between your taps and averages the most recent ones into a tempo, so it settles after four or five taps. Pause for a couple of seconds and it resets, ready for a new count.

Tap vs. automatic detection

Automatic BPM detection reads the tempo from an audio file; tapping reads it from you. Tapping wins when there's no file to upload, music playing in the room, a live rehearsal, a track in another app, or when a song's rhythm confuses automatic tools. They're a good cross-check on each other.

Half-time and double-time

If the number feels off by 2×, you're probably tapping a different pulse than the one you mean, 70 vs 140 BPM, say. Both are valid multiples of the same beat; tap whichever pulse you'd count out loud and trust that.
