Tap the pad — or press the Space bar — in time with the music. MagicBPM averages the gaps between your taps into a steady BPM, ignoring the odd mistap or skipped beat.
Beats per minute
--
Tip: tap on the beat you feel most strongly (usually the “1”). Stop for a couple of seconds and it starts a fresh count.
How it works
Every time you tap, the tool measures the interval to your previous tap and converts the average into beats per minute (BPM = 60 ÷ seconds-per-beat). It keeps a rolling window of your last eight taps, drops any single tap that lands far off the beat, and folds a clean skipped beat back down — so one fumble won’t throw the number off. When your taps get steady, the Steadiness light turns green.
A single off-beat tap is filtered out of the average, so the reading stays put instead of jumping.
Tap the pad on a phone, or hit the spacebar on a laptop — whichever keeps you on the beat.

MagicBPM for iPhone
The MagicBPM app detects the tempo of any music through your iPhone’s microphone in real time — on-device, no tapping, no recording. Tap tempo is built in too, for when there’s nothing playing.
Get MagicBPM — freeGood to know
Play the song, then tap the pad (or press the spacebar) once on every beat. After four or five taps a steady BPM appears, averaged from the time between your taps. Keep tapping to refine it.
Four taps give a first estimate; six to eight give a reliable one. The tool averages your most recent eight intervals and ignores the occasional mistap, so a longer, steady run is more accurate.
A cleanly skipped beat is detected and folded back to a single beat, so it won’t drag the average. A wildly off tap is treated as an outlier and dropped. If you pause for more than a couple of seconds, the count resets and you start fresh.
Yes — that’s what the MagicBPM iPhone app is for. It listens through the microphone and detects the BPM of music automatically, on-device. This web tap tool is the manual cross-check.
