CourtsidePlay supports full BWF-style rally scoring on iPhone and Apple Watch: 21 points per game (30 cap at deuce), best of three games, configurable points and games for club formats. A dedicated badminton motion pipeline detects serves at rally start, lobs, smashes and groundstrokes — with the current server synced between devices in real time.
Choose Badminton from the four-sport picker, then singles or doubles. Score from iPhone or Apple Watch; the serving indicator on Watch shows who should serve the next rally. After each point, the serve window reopens so only the current server's first stroke can be classified as Serve — mid-rally swings stay forehands, backhands, drops, slices or lobs.
