SwingSense Tennis

Swing your Apple Watch and experience real-time 3D tennis shot simulation anywhere, anytime!

SwingSense is a standalone watchOS tennis swing simulator. Using Apple Watch high-frequency IMU motion sensors and on-device CoreML machine learning models, SwingSense detects your tennis strokes in real time and generates dynamic 3D ball flight trajectories and physics simulations.

KEY FEATURES: • Real-time Stroke Recognition: Accurately detects forehand, backhand, serve, volley, and slice strokes. • 3D Flight & Replay Simulation: Estimates initial ball speed, spin RPM, and launch angles with interactive court landings and bounces. • Adaptive High-Hz Sampling: Fully optimized for Apple Watch Ultra (200Hz) and standard watchOS hardware (100Hz). • Wearing & Crown Alignment: Automatic Digital Crown orientation detection and coordinate system calibration for right-handed, left-handed, and reverse wrist wearing. • One-Tap Audio Mute: Toggle audio feedback directly on the main control panel while retaining tactile haptic vibration for stroke impacts. • Practice Session Analytics: Tracks stroke distribution, speed ranges, and spin rates during practice workouts.

Note: SwingSense is an entertainment swing simulator with estimated ball trajectories. It is not a professional radar or optical tracking device.
