Average human reaction time is about 270 ms. Under 220 ms? You're built different.
Reflex Test — a free reaction time test that runs in your browser
How fast are your reflexes, really? This free reaction time test measures the gap between the screen turning green and your tap, in milliseconds. You get five rounds; your average decides your rank — from 🦥 Sloth all the way to ⚡ Lightning. Tap too early on red and the round doesn't count, so no gambling on the timer.
It works on any phone or computer with no download and no sign-up. Your best average is saved on your device, which makes this dangerously replayable: there is always a friend to out-click and a personal best to shave 10 more milliseconds off.
What's a good reaction time?
- Under 220 ms — exceptional; typical of competitive gamers and athletes.
- 220–270 ms — faster than most people.
- 270–320 ms — right around the human average.
- Over 320 ms — slower day? Caffeine and good sleep genuinely help.
Reaction time varies with age, fatigue, screen latency and even time of day — which is exactly why people keep coming back to retest.
