Reflex — Reaction Training App

Reflex is a reaction training app that improves reaction time, agility, and decision-making through interactive cognitive-motor training drills. By combining brain challenges with real physical movement, Reflex helps athletes, coaches, and active individuals develop faster information processing and more efficient physical reactions.

How It Wåorks

Reflex uses randomized visual and audio stimuli (colors, numbers, arrows, and more) to deliver game-like reaction training drills. When a stimulus appears on your device, you react with real physical movement — sprinting, shuffling, jumping, or touching targets. This trains your brain and body simultaneously, helping improve reaction time, agility, coordination, and decision-making in sports and everyday situations.
