Skeleton on every video
Your skeleton follows you as the video plays. Step frame by frame, slow it to ½× or ¼×, or go fullscreen.
Tennis swing analysis for iPhone
See your swing the way a coach does.
Film a forehand, backhand or serve. CourtLab finds every shot, draws your skeleton on the video, scores your technique, and tells you the one thing to fix next. Then it gives you the drills and workouts to fix it.
