About Reaction Timer

Reaction Timer is a scientifically grounded reflex measurement tool that presents one of gaming's most honest challenges: can you react to a visual cue in under 200 milliseconds? The average human reaction time is 250ms, so beating that threshold feels genuinely satisfying. The game prevents anticipatory clicking by randomizing the delay before the cue appears, ensuring every result reflects true neural response speed. Elite players and gamers use this to benchmark their input lag setup and monitor cognitive performance — faster times in the morning vs. evening reveal real patterns in personal alertness.
