How Reaction Time Test Works
Click the colored panel to start. Wait for the screen to turn green — clicking before it turns green counts as 'too early'. When it turns green, click as fast as you can. Your reaction time is recorded in milliseconds. Take multiple attempts to see your average and best times.
Why Use Reaction Time Test?
Reaction time is important for driving safety, sports performance, and gaming. Tracking it over time can reveal improvements from training or declines from fatigue. Average human reaction time is 200-300ms.
