Reaction Light Trainer: Reflex

Your phones become the reaction lights — no costly pods to buy. Sharpen reaction time, reflexes & agility on one device, or link phones & Apple Watch to compete. Free.

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
