A browser-local tap counter that measures BPM, elapsed time, interval spread, and recent-session variation.

Landing page captured for the 2026-08-29 issue.

Field notes

The tool treats tapping as a temporary measurement session rather than as an attempt to identify the correct musical beat. It records each gap between accepted taps, reports both rate and duration statistics, and can apply a recent-interval window without erasing the full sequence. The page explains that ten taps yield nine intervals and demonstrates the calculation with four gaps ranging from 495 to 510 milliseconds. A reset timeout prevents unrelated attempts from being merged after a pause.
