Want to test your reflexes online? Our free reflex test measures how fast you can respond to a visual signal — the same reaction-time test used in cognitive psychology, gaming benchmarks, and sports performance labs. No signup, works on phone or desktop, results in under a minute.
Our Reaction Time game shows you a signal, you click as fast as you can, and it averages your response across multiple trials — the same protocol used in cognitive labs.
The typical adult visual reaction time is 200–270 ms. Under 200 ms is fast; under 180 ms is elite. Auditory reactions are ~40 ms faster than visual.
Yes. Regular reaction-time practice reliably shaves 10–30 ms off your average within 2–3 weeks. The bigger gains come from reducing variability, not raw speed.
Massively. Sleep loss can slow reaction time by 50+ ms. Caffeine (200 mg) typically speeds it up 5–15 ms. Test at the same time of day for meaningful comparisons.
