Reaction Light Trainer
Read full descriptionHide full description
Reaction Light Trainer turns the phones you already own into a full reaction-light system β the kind of setup coaches pay hundreds for, free. Lights flash in random, unpredictable colors and positions; you react and hit them as fast as you can. Because the cue is unplanned, you train true REACTIVE agility, reaction time, reflexes and hand-eye coordination β not a memorized pattern. That's the difference between reaction lights and cones or ladders, and why athletes use them. KEY FEATURES - Multi-device stations: link several phones (and Apple Watch) over Wi-Fi and spread them out as reaction pods β build lines, boxes, arcs and circuits for a whole squad. Any device hosts and starts. - Solo drills on a single phone: 30s challenge, multi-light, color go/no-go, footwork. - Go / no-go: tap only the right color to train decision speed and impulse control. - Adaptive difficulty: the deadline tightens as you get faster, keeping you at your limit. - Rounds & rest, like real interval / SAQ training. - Live stats & competition: reaction time, hits, misses, accuracy, fastest/average, per-player results and head-to-head racing. BUILT FOR - Speed, agility & quickness (SAQ), reactive agility, change of direction - Soccer & goalkeepers, basketball, tennis, badminton, table tennis, hockey, volleyball - Boxing, MMA & martial arts β hand speed and defensive reflexes - Rehab & return-to-play, balance, proprioception and sports vision - Team & youth coaching, PE classes, group fitness, and cognitive / brain training A flexible, affordable alternative to expensive reaction-light pods β using the devices you already have.
