iPhone
New in 2.0: film one serve from several iPhones at once. Analysis runs on your iPhone. No account, and your videos never go to a server. Try the sample serves free.
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 together: one iPhone hosts and others join by scanning its code. One tap starts every camera, and the host reads the serve from the side, back and front together.
• 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
Analysis runs on your iPhone. No account, no ads, no tracking. Your videos never go to a server. In a filming session they travel phone to phone over a direct link.
WHAT'S FREE
The bundled sample serves, your saved history and filming for a friend's session are always free. TennisServe Pro unlocks analysis of your own serves, including the ones you film together: a 14-day free trial, then $6.99 a month or $39.99 a year. Cancel any time in Settings.
TennisServe is a training aid. It estimates body positions from 2-D video and is not medical or injury advice.
