About Reflex Tap
Reflex Tap is a minimalist reaction game. A coloured square flashes on the screen. You tap as fast as you possibly can. The game measures your reaction time in milliseconds and plots your average across rounds. It is part game, part lab instrument, and a small dose of humility for everyone who plays.
Reflex Tap is genuinely useful as a daily check-in. Your reaction time is a sensitive measure of how you are functioning today — sleep quality, caffeine, focus state. A bad day reads 30–50ms slower than a good day, and the game shows you that difference clearly. Knowing your number is a small but real life-edge.
This Reflex Tap is free, browser-based and works on touch, mouse and keyboard. There is no sign-up and no installer. Your best average time is stored locally between sessions. It is one of the cleanest, fastest games on the site — a thirty-second focus check before any task that demands attention.
