Race Reflex: Reaction Test

Race Reflex is a pure test of reaction speed, inspired by the starting procedure of motorsport.

Five red lights come on, one by one. They hold... then all go dark at once. The moment they do, tap. React too early and it's a jump start - no time recorded. React clean, and your reaction time is measured to the millisecond.

That's the whole game. No menus to grind through, no forced timers, no ads interrupting your run. Just you, the lights, and the gap between seeing and moving.

HOW TO PLAY

• Tap to start the sequence
• Watch the five lights fill up
• Wait through the random hold - don't anticipate
• Tap the instant the lights go out
• Beat your best time

FEATURES

• One-tap gameplay anyone can pick up in seconds
• Millisecond-accurate timing

Typical human reaction time is around 200-250 milliseconds. The fastest drivers hit the 150s. Where do you land?

Race Reflex is free, lightweight, and respects your time and your data.
