Stroke detection
Recognizes common practice strokes such as forehand, backhand, slice, volley, and serve or overhead motion.
Apple Watch tennis swing tracker
Know every swing from your wrist.
SwingSense uses Apple Watch motion sensors to detect tennis strokes and show estimated speed, spin, landing result, and replay trajectory.
Designed for practice feedback. Ball speed and trajectories are estimated, not professional line-calling data.
SwingSense
Ready on hard court
Take one swing
Built for real practice
Fast feedback without setting up a camera.
Estimated replay
Shows a compact trajectory replay with estimated landing result, speed, spin style, and ball path.
Training sessions
Record multiple swings in a session and review your practice rhythm, stroke mix, and recent results.
Simple setup
Tell SwingSense how you wear the watch and which hand holds the racket.
The app uses that setup to normalize motion, reduce left and right hand confusion, and make the replay feel closer to your court position.
- Choose wrist side and racket hand
- Start a single swing or a training session
- Review stroke type and estimated trajectory on your watch
Beta testing
Help tune the model with real swings.
TestFlight testers can try single swing mode, training sessions, and replay feedback. Your feedback helps improve recognition across different players, grips, and swing speeds.
