Description
Reaction Light Trainer turns the phones you already own into a full reaction-light system — 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 — 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 — 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 — 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 — using the devices you already have.
