BoPMan
Extension Actions
Tap to find your BPM. Lock it in. BoPMan pulses at that tempo so you can keep the beat.
What do you do when you hear a beat? You bop, man.
Most tap tempo tools stop at showing you a number. BoPMan goes further - lock in a BPM and a visual pulse keeps beating so you can use it hands-free while you work.
How it works
Tap the beat with your mouse, keyboard, or spacebar. BoPMan calculates a rolling average from your taps and shows a live reading from the second tap onwards. When you're happy with the reading, lock it - the extension switches to a persistent pulsing display that keeps the tempo visible even after you close and reopen the popup.
