Grid Snap is a clean launch reaction trainer built around a five-light start sequence. Hold to stage, wait for the lights, then release as fast as you can when they go out.
Track your best and average reaction times, catch false starts, and customise the look with premium colour themes. It's designed for fast daily practice with a minimal, focused interface.
