Reflex Trainer measures your reaction time with precision, using real motion detected by your Apple Watch or iPhone. How It Works A visual stimulus flashes on your screen. React as fast as you can by throwing a punch (detected by your Apple Watch or iPhone accelerometer at 50Hz). Your reaction time is measured in milliseconds. Two Training Modes Combat Sports Mode Designed for boxing, MMA, kickboxing, and martial arts athletes. Throw a real punch when you see the flash. Your Apple Watch detects the motion, no screen tapping needed. Hold your phone in your fist as a fallback when training without a watch. General Reaction Mode A classic reaction time test for anyone. Tap the screen or move your wrist the instant you see the stimulus. Perfect for gamers, athletes, and anyone who wants to measure and improve their reflexes. Live 1v1 Duels Challenge a friend to a real-time reflex showdown. Share a code over iMessage or jump into the public lobby for a quick match. Both phones fire the same stimulus at the exact same moment, with server-authoritative timing keeping every round fair. Best of 1, 3, 5, or 10 rounds. Fastest reaction wins. Friends, Stats & History (NEW) Your Profile now has three tabs: Stats for your personal bests, History for every session you've ever run, and Friends for the people you train against. Add friends by username, get a push notification when they accept, and tap any past session to see every individual rep. Compare reaction times head to head and track your progress over time. Three Difficulty Levels - Easy: punch when you see red - Medium: no early punches allowed - Hard: distractor flashes appear, only red counts Climb the Leaderboards Sign in with Apple to track personal bests and rank globally. Every solo session and every clean duel feeds the same leaderboard, ranked by mode, difficulty, and round count. Your duel results count toward your personal bests too. Key Features - Apple Watch integration with real-time accelerometer punch detection - Live 1v1 duels with server-synchronised stimulus timing - Public lobby and quick match for instant duels - Friends list with mutual approval and push notifications - Full session history with per-rep breakdown - Three difficulty levels (Easy, Medium, Hard) - Customisable rounds (1 to 10 per session) - Per-round breakdown with average, best, and worst times - Global and weekly leaderboards - Personal bests tracked per mode and difficulty - Sign in with Apple (no email or password required) - Works with or without Apple Watch - No ads.
