How it works
Press start, wait until the test area turns green, then click as quickly as possible.
Don’t click early
If you click before the screen turns green, the test counts it as an early click and asks you to restart.
Try a few times
Reaction time can vary from attempt to attempt. Your best score is usually more useful than one single result.
Results can vary depending on device, display refresh rate, mouse, touch latency, and browser performance.
