RallyTrace: Badminton Score

Remember every badminton point on Apple Watch, then review each match on iPhone.

ON COURT • Score singles and doubles, choose a match format, undo points and see who serves. • Enable spoken scores, pause when needed, and save offline on your watch.

AFTER THE MATCH • Review game scores and point-by-point score flow. • Find Watch matches and manual entries by player name, date or source. • See playing time, available heart rate and active energy, swing estimates and typical wrist rotation speed. • Review regular day, week, month and year statistics and trends. • Preview a match card before sharing. Names and health data are hidden by default; private notes are never shared.

HEALTH AND ESTIMATES Health access is optional; scoring works without it. Apple Watch measures heart rate and Apple estimates active energy. Swings, movement types and wrist speed are estimates. Wrist angular speed is not racket-head speed or shuttle speed. These readings are not for medical diagnosis or skill assessment. Missing data is not filled with invented values.
