Slow-mo, frame-by-frame, draw lines and angles, side-by-side compare
Pick your event. The numbers and the drills change with it.
No clips yet
Record an athlete or import a clip. Everything stays on this phone. Nothing uploads.
Controls sit on the video: play, frame step, speed, then the tools: Line, Angle (tap three points), Draw, Skeleton, and Track zone (drag a box over the lanes so spectators are ignored and distant runners get found). Pinch to zoom, double-tap to jump in. No tool is on until you tap one; bare touches just zoom and pan. Nothing leaves this phone.
