Live rolling average
Averages your most recent taps so the BPM reading stabilizes as you keep tapping.

How to use the tap tempo finder
This free online tap tempo tool measures the time between consecutive taps to work out the tempo of a beat you hear or feel, with no need to count beats yourself.
- Start tappingClick the Tap button or press spacebar in time with the beat.
- Watch the BPM updateAfter your second tap, a live BPM reading appears and refines with each further tap.
- Reset for a new tempoPress Reset, or simply pause for a couple of seconds and start tapping a new beat.
How tap tempo detection works
Every tap is timestamped using the browser's high-resolution clock. The tool looks at the gaps between your most recent taps and converts the average gap into beats per minute.
Rolling window
Only the last several taps are used in the average, up to a rolling window of around ten, so the BPM reading tracks a tempo change instead of being dragged down by taps from minutes ago.
The BPM formula
Beats per minute is calculated as 60,000 divided by the average interval between taps in milliseconds. Faster, closer-together taps produce a higher BPM.
Automatic reset
If more than about two seconds pass without a tap, the history clears automatically so a long pause doesn't get counted as part of the tempo.
Common use cases
Tap tempo is handy for finding a song's BPM by ear, setting a DJ or metronome tempo, syncing a click track to a live performer, or matching a workout playlist to your pace.
Tap tempo FAQ
Quick answers about accuracy, controls, and resets.
How does tap tempo calculate BPM?
It measures the time between your most recent taps, averages the last several intervals, then converts the average interval to beats per minute using 60,000 divided by the average interval in milliseconds.
How many taps do I need?
Two taps give a rough estimate. Accuracy improves with each additional tap, up to a rolling window of the last several taps, which smooths out small timing variations.
Can I use my keyboard instead of clicking?
Yes. Press the spacebar in time with the beat, which works the same as clicking the Tap button and is often easier to keep steady.
Why did my BPM reset on its own?
If more than a couple of seconds pass between taps, the tool assumes you're starting a new tempo and clears the tap history so an old, unrelated interval doesn't skew the result.
Is this the same as a metronome?
No, it's the reverse. A metronome plays a click at a BPM you set; this tool listens to your taps and works out the BPM for you.
