Punch faster. Tap quicker. Real-time reaction duels with friends.
Reflex Trainer measures your true reaction time, then turns it into a sport. Whether you're a boxer training for the next bag round, a fighter sharpening your reads, or just someone who wants to know how fast they actually are - Reflex Trainer gives you a precise, repeatable measurement and a way to push it lower. -- TWO TEST MODES -- • Combat Sports - A visual stimulus fires; you throw a punch. The phone's accelerometer detects the impact and times it to the millisecond. Built for athletes, but anyone can use it. • General Reaction - Tap-based reaction test. Same precision, no movement required. For when you're sitting on the bus. -- LIVE DUELS -- Challenge friends to head-to-head reaction battles. Best of 3, 5, or 7. Real-time scoring with a server-synchronised clock - no laggy peer-to-peer, no excuses. Win streaks, rematch flow, and a public lobby if you want quick-match action with strangers. -- FRIENDS & PROFILE -- Add friends by username or shareable code. See their last reaction time, their personal best, and your full head-to-head record. Get push notifications when a friend beats their PB or finishes a duel against you - rivalry stays alive even when you're not in the app. -- CROSS-PLATFORM -- Your account, history, and friends list sync across iOS (with Apple Watch support for wrist-mounted punch detection), Android, and the web app at reflex-trainer.com. Sign in once on any platform and pick up where you left off. -- LEADERBOARDS -- Global rankings for both modes. Filter by reps (1–10) and see where you land. Personal bests are tracked separately so you always know what to beat. -- BUILT WITH RESPECT FOR YOUR TIME AND DATA -- • No ads. Ever. • No third-party analytics. We don't sell or share your data. • You can request full account deletion any time from reflex-trainer.com/privacy/delete. -- WHO IT'S FOR -- • Boxers, MMA fighters, kickboxers, BJJ practitioners - anyone whose sport rewards faster reactions. • Esports players who want to train the underlying reflex independently of any specific game. • Athletes recovering from concussion or injury who want to track reaction-time recovery. • Anyone curious how their reflexes compare to friends. Train. Test. Duel.
