Reaction Time

A clean, no-nonsense reaction time test. A circle turns red — wait for it to go green, then tap as fast as you can. Five rounds, one average. That's your score.

No distractions. No ads every 10 seconds. Just you, the circle, and your reflexes.

HOW IT WORKS
• A red circle appears on screen
• After a random delay, it turns green
• Tap it as fast as possible
• Repeat 5 times — your average reaction time in milliseconds is your result

150–350 ms — Good. Solidly above average.
350–500 ms — Average. Completely normal for most adults.
Over 500 ms — Keep practicing. Reaction time improves with training.

Simple. Accurate. Addictive.
