Short-form for the next release finally keeps up.
Follow the pulse with your finger, mouse or Space key. A few steady taps turn the rhythm in your head into beats per minute.
Tap at least 3 times to find your tempo
Tap the main beat you would nod your head to—not each hi-hat or lyric syllable. Keep tapping for several beats to settle the estimate.


Hear a song you want to practice? Tap along with its main beat using a mouse, a touchscreen, or Space while the tap control is focused. This free tap tempo tool needs no file or microphone. Keep your taps on the underlying pulse rather than every drum hit, then set the same number on the free metronome.

Tap at least three times for an initial estimate, then keep going until your timing feels settled. Play the estimated tempo and listen to whether the click follows the song's main pulse. If you have the audio file, confirm it with the BPM finder. If the result feels twice as fast or half as fast, try counting the beat differently and tap again.
Play your track in another app or listen to a live performance. No audio file is needed.
Click or touch the tap pad. With the panel focused, you can also use Space. Make at least three taps.
Read the estimated BPM and listen to the matching metronome. Reset to start over; a long pause starts a new tapping sequence.

The tapper measures time between your taps and estimates beats per minute from those intervals. More consistent taps make the estimate steadier; it cannot know the correct beat if your taps follow a subdivision.
