HOW FAST ARE YOU?
When the panel turns green, react. We measure the gap in milliseconds and put it next to the two figures that matter: an elite boxer sits near 150ms, the average adult around 250ms.
THE TWO NUMBERS YOU ARE CHASING
- ELITE BOXER
- 150ms
- AVERAGE ADULT
- 250ms
Your result is scored against those two figures and nothing else. Attempts are kept in this browser so you can chase your own best — they are never uploaded, and there is no global ranking to game.
