CPS test
Clicks per second from 1 to 60 seconds, with a moving-target mode, personal bests and history.
Test hub
Every mouse test, one place
8 free tools to measure your clicking, aim and reactions, and to check your mouse for faults like double-clicking switches, a jumpy scroll wheel or a low polling rate.
Double click test
Check whether your mouse registers single and double clicks cleanly.
Reaction time
Wait for green, then click. Five rounds, averaged, with your best saved.
Aim trainer
Hit 20, 30 or 50 targets as fast as you can. Tracks time, accuracy and time per target.
Polling rate test
See how often your mouse reports its position: 125, 500, 1000 Hz or more.
Scroll wheel test
Catch a scroll wheel that jumps the wrong way, a classic sign of a worn encoder.
Mouse button test
Press every button, including side buttons, and spot switches that double-click by themselves.
Sensitivity converter
Convert your sensitivity between CS2, Valorant, Apex, Overwatch 2 and more.
