Reaction Time Test
Tap the pad to start, wait for the colour change, then click as fast as you can. Your time shows in milliseconds. Early clicks do not count — you will see a quick “too soon” message and can start that try again.
Scores stay in this tab for your last few tries so you can chase a personal best. Nothing is uploaded or stored on a server. It is a casual game, not a medical or driving test.
Click to start
When the pad turns green, click as fast as you can.
