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
