Film one serve. TennisServe finds the one thing costing you the most and gives you a drill for it.
HOW IT WORKS
• Record in the app in slow motion, or pick a Slo-mo clip from Photos.
• The app tracks your body through all eight parts of the serve: stance, toss, legs and coil, racket drop, swing up, contact, follow-through, landing.
• More than 30 checks are rated against published serve biomechanics, foundation first: legs and base before arm and wrist.
• Coach mode shows one fix at a time, with a drill and a feel cue. Detailed mode shows every measurement, stage stills, joint angles and charts.
• The score is honest about its reach: it shows what the camera measured and how far it can rise once you rate the checks video cannot see or add a second camera.
• Film again and see the fix clear. Compare two serves side by side, or the same serve from two phones.
• Share a PDF report.
PRIVATE BY DESIGN
