Race Start Reaction
Fast Reaction Time Test
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
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.
