Frequently Asked Questions

How accurate is the BPM calculator?

The calculator uses a rolling average of your last taps to smooth out timing variations. For best results, tap steadily for at least 4-8 beats.

Can I use the keyboard instead of clicking?

Yes! Press the Spacebar to tap — perfect for keeping your hands free while listening.

Is my data saved or sent anywhere?

No. All calculations happen entirely within your browser. We do not store, transmit, or log any of your tap data.
