About Reaction Time Test
The Reaction Time Test measures how quickly you can respond to a visual stimulus — a simple but scientifically meaningful measure of neural processing speed. The average human reaction time is 200-300ms. Athletes, gamers, and fighter pilots typically have reaction times below 200ms. This test is used in sports science, cognitive research, and just for fun.
How to Use
Click 'Start' and wait for the screen to turn green — don't click too early! The moment it turns green, click as fast as you can. Your reaction time in milliseconds is shown immediately. Complete multiple attempts to see your average, best, and worst times with a trend chart.
Common Use Cases
- Testing and improving gaming reflexes for competitive play
- Comparing reaction times before and after coffee, sleep, or exercise
- A fun way to compete with friends and colleagues
- Sports training — measuring athlete reaction speed
- Checking if medications or fatigue are affecting cognitive response time
