How the swing detector works
A dedicated CoreMotion pipeline runs on the Watch for the full match. The algorithm looks for an impact-shaped acceleration spike combined with a matching gyroscope rotation, then filters out noise from arm swings that aren't contact with a ball.
- Detects impacts in real time while the match is active.
- Drains the swing buffer at the end of each point so every shot lands in the correct rally.
- Calibrates intensity (0–100) based on peak G-force and rotation speed of the wrist.
- Works with your dominant hand (set in your player profile) so left-handed players are handled correctly.
Wear the Watch on your dominant hand
Swing metrics are most accurate when the Watch is on the racket-holding arm. CourtsidePlay uses the dominant hand and play style you set in your Player Profile to interpret motion signatures.
