How accurate is the BPM calculation?

Accuracy depends on how evenly you tap. The tool uses a rolling average of your last 4 to 8 taps, which filters out individual timing errors. After about 8 consistent taps you can expect results within 1-2 BPM of the true tempo. Using the spacebar tends to produce more precise timing than mouse clicks.

What does the "Locked in" badge mean?

"Locked in" appears when the standard deviation of your recent tap intervals is less than 5% of the average interval, meaning your tapping is very consistent. "Detecting..." shows while fewer than 4 taps have been recorded or while consistency is still low.

Why does it reset after I stop tapping?

Any gap longer than 3 seconds between taps is treated as a new session. This prevents a long pause from skewing the rolling average with a very large interval. When a reset occurs the BPM display clears and you can start fresh.

What are the tempo classification names?

The tool uses standard Italian musical tempo markings: Largo (under 60 BPM), Andante (60-85 BPM), Moderato (86-120 BPM), Allegro (121-156 BPM), and Presto (157 BPM and above). These are the same terms you will find in sheet music and music theory.

How it works

Open a song in your music player and start listening to the beat.
Tap the large TAP button or press the spacebar in time with every beat of the song.
After 4 or more taps, the BPM display updates in real time using a rolling average of your recent taps.
Keep tapping to improve accuracy — the confidence badge will switch from "Detecting..." to "Locked in" when your taps are consistent.
Press Reset to start over, or simply stop tapping for 3 seconds and the counter resets automatically.
