About this tool
Reaction Time Test checks how quickly you respond to a visual signal. You wait calmly, the screen changes, and you click at once; the gap between the change and your click is your reaction time in milliseconds. Repeating the test a few times gives a fairer picture than a single lucky or unlucky try, since attention naturally varies.
