Fresh Space key-down events count; held-key automatic repeats do not. The final tapping rate divides accepted presses by the selected seconds. Other keys are excluded from this dedicated counter.
The result counts physical key-down events rather than operating-system repeats. Fifty taps in ten seconds means five accepted taps per second.
If Space scrolls the document, focus the test area again. Accessibility tools or browser shortcuts can intercept key events before the counter receives them.
If the page scrolls, return focus to the test area. Compare the same duration and keyboard, and distinguish a short burst from sustained tapping.
No. Automatic repeat events are excluded. You need separate releases and presses, which makes the result useful for comparing actual tapping rhythm.
Focus the active surface, choose a duration and press Space to start. Release the key fully between presses and continue until the timer ends.
No. Open the interactive tool above in a modern browser. The instructions and explanations are available even with JavaScript disabled; running a test needs JavaScript.
Power settings, background tasks, browser scheduling, operating-system input processing and device settings affect measurements. Compare repeated attempts with identical settings rather than the single highest score.
