Five lights on. All out. Tap. Train your reaction speed with a motorsport-calibrated tier system, Game Center leaderboards, and four pro-level reflex modes.
Your brain takes about 250 ms to turn a flash of light into a tap. F1 drivers do it in under 200. Reflex is a reaction trainer built to close that gap.
Every session is timed in milliseconds. Every result is graded against a motorsport-calibrated tier system — from Lightning under 170 ms to Back of the Grid above 320 ms — so you always know where you stand and what to beat next.
FOUR GAME MODES
• Lights Out — The classic starting-light sequence. Five lights on. All out. Tap. One false start ends the run.
• Simple Reaction — A single cue, a single tap. The purest measure of your reaction time.
• Batak — 12 glowing targets. Hit them as fast as they appear. Three sub-modes: fixed time, target count, endurance.
• Peripheral Vision — Green dots at the edge of your vision, red distractors trying to fool you. Four difficulty levels train the full field of view.
TRAIN LIKE A PRO
Focus under pressure. Sharpen hand-eye coordination. Extend your peripheral vision. Build the reflexes that separate a podium from the back of the grid — one tap at a time.
