React Trainer

React Trainer — Agility Training & Reaction Drills

Build faster reflexes with random-interval training drills. Create a drill, hit play, and react to unpredictable visual flashes and audio beeps that keep you sharp.

How it works:

• Create custom drills — name them, set duration (15s to 5min), and dial in your min/max cue interval
• Pick one or multiple flash colors (green, red, blue, yellow, orange)
• A 3-2-1 countdown kicks off the drill, then cues fire at random intervals within your range
• When you're done, see your stats: total cues, drill duration, and average interval between cues

Built for any sport that demands quick reactions:

• Tennis: split step timing, volley reactions, serve returns
• Boxing: jab-cross combos, slip & counter, defensive reflexes
• Soccer: first touch, goalkeeper saves, direction changes
• Basketball: fast breaks, defensive slides, pick & roll decisions
• Or any training where unpredictable cues sharpen your instincts
