About Clicks Per Minute

Clicks Per Minute is a single-purpose measuring instrument: it counts presses inside an interval you choose and reports the rate as clicks per minute.

It exists because most click speed tests report a number without saying what was measured. This one states the clock, the event, the interval and the rounding, and it publishes the arithmetic on the same page as the result.

• Clock. performance.now(), read at the moment the browser dispatches pointerdown, at 0.1-millisecond resolution.
• Start. The interval opens on your first press, so reaction time is excluded from the rate.
• End. A timer closes a time-mode interval on schedule even in a throttled tab; the animation loop only drives the sweep hand.
• Elapsed. Reported time is clamped to the nominal interval, so CPM is exact rather than approximately exact.
• Rate. Clicks ÷ elapsed seconds × 60, rounded to the nearest whole click per minute.

• No accounts, no leaderboard. A global leaderboard on an unverifiable input is a ranking of auto-clickers.
• No upload. Personal bests are written to this browser's local storage and never sent anywhere.
• No claim of authority. Where a world record is disputed, this site says so and shows the arithmetic instead of repeating the figure.
