اختبار سرعة النقر (CPS) والنقر المزدوج.

Works with a mouse, touchpad or touch screen. Everything is calculated in your browser; nothing you type is uploaded.

Clicks are timed with the browser’s high-resolution clock; gaps under 60 ms are faster than people normally click and often come from a worn mouse switch.

Fifty clicks in 5 seconds is 10 CPS; any two clicks less than 60 ms apart are flagged as a possible switch fault.
