Reaction Time Test
Click the moment the screen turns green. Measures your reaction time in milliseconds over 5 attempts and gives you an average. Clicking too early resets that attempt. Under 200ms is genuinely fast.
How to use
- Click the box to begin. It turns green after a random delay - could be 1 second, could be 4.
- The moment it turns green, click it as fast as you can. Your reaction time in milliseconds is displayed.
- Clicking too early resets that attempt. Don't guess, just react when you see green.
- Complete 5 attempts to get your average score. Sub-200ms is excellent!
