## What is RallyArc?

Keep the score between rallies without reaching for your phone. RallyArc records either side's points on Apple Watch and lets you undo the most recent point.

Choose your rules before play
Use 21, 15 or 11 point badminton presets or single-game practice. Tennis mode scores one game with deuce and advantage; it does not track sets or tiebreaks.

Pause, correct and continue
Lock scoring between rallies, pause play and review the locally saved score. Reopen a match ended manually before starting another match. If a winning point ended the match, unlock corrections and undo that point. Point-by-point scoring does not require a live iPhone connection.

What the iPhone app does
A paired iPhone can receive watch match snapshots, show history and create a score overlay for a video you select. Delivery depends on pairing and the system; phone history is a copy of the watch's original record. Optional workout recording and heart-rate views require the relevant Apple Health permissions.

Trial and one-time unlock
Activate a 21-day trial with no automatic charge. After expiry, starting new matches requires a one-time unlock: US$4.99 in the US or ¥38 in China. Confirm the price on the purchase sheet. Finish matches already started and keep your history. Restore purchases with the same Apple account after reinstalling or changing devices. Apple and Huawei purchases are separate.
