Real-time tennis player and ball detection on-device. Track ball speed, trajectories, and player movement during practice or matches. Privacy-first. SpeedTennis turns your iPhone into a real-time tennis analysis system. Using on-device machine learning, it detects players and the ball from the camera feed, tracks ball trajectory and speed, and overlays player movement — all live, with no internet connection required. KEY FEATURES • Real-time ball detection SpeedTennis identifies the tennis ball frame by frame and draws its trajectory as a dashed line, so you can see the path of every shot. • Player tracking Each player is boxed and tracked across frames, with an optional simplified label mode for cleaner playback. • Shot speed estimation Ball speed is computed from the trajectory and displayed on screen, giving you instant feedback on serve or groundstroke pace. • HD recording with overlays Record your practice with detection overlays baked in. Videos are saved to the in-app library, with upright text and proper orientation. • Zoom control Pinch or slide to zoom the camera for tighter shots when you need a closer view of the action. • Adjustable thresholds Fine-tune detection sensitivity for players, balls, and rackets to match your lighting and court conditions. • Re-detect button Tap to clear all tracks and restart detection — useful when the camera picks up false positives or you switch scenes. • Works fully offline No cloud, no accounts, no data collection. Your practice stays private on your device. WHO IT'S FOR • Recreational players who want instant feedback on their shots • Coaches reviewing student technique on court • Parents filming kids' lessons • Anyone curious about their ball speed and trajectory PRIVACY SpeedTennis performs all detection on the device. The camera feed is processed locally and never uploaded. Recording permissions are clearly requested upfront. SUPPORT If you encounter issues, please contact support from the App Store listing. We respond to every message. Enjoy your practice.
