Race Start Reaction

Test your reflexes, chase your personal best, and compete on the global leaderboard in a realistic five-light race start challenge.

How fast can you react when the lights go out?

Race Start Reaction is a focused reaction-time test inspired by the excitement of a Grand Prix starting grid. Train your reflexes, improve your focus, and discover how quickly you can react to the lights.

KEY FEATURES

• Precision Reaction Timer Measure your response time to the millisecond and track results down to three decimal places.

• Realistic Five-Light Race Start Start the sequence, stay focused, and react as soon as all five lights go out. Tap too early and you will receive a False Start.

• Personal Best and Progress History Review your best result, recent attempts, average reaction time, fastest result, and progress over time. Progress History is available to every player.

• Global Game Center Leaderboard Compare your best reaction time with players around the world and aim for the top of the Fastest Reaction Times leaderboard. Game Center sign-in is optional; you can play without an account.

• Light and Dark Appearance Choose the Light or Dark interface from Settings. Your preference is saved for your next session.

HOW IT WORKS

1. Tap START to begin the race-start sequence.
2. Wait while the five lights are on.
3. React when all the lights go out.
4. Review your time and compare it with your personal best.

A false start is recorded when you tap before the lights go out. Try again, refine your timing, and build a faster, more consistent reaction.
