Your result
Quick guide
Keep the default five-second mode or select another duration.
Press Start, then click, tap, or use the focused target button until time runs out.
Review your total clicks and average clicks per second, then try again if you like.
Counting details
CPS means clicks per second. The result divides valid target clicks by the selected test duration.
Five seconds is a balanced default. One second is a quick burst, while 10 or 30 seconds places more emphasis on maintaining a steady pace.
Input hardware and technique affect how quickly activations register. Compare attempts made with the same device for a more consistent personal reference.
