怎样加球友、互看 Watch 比赛？
在 iPhone“球友”页完成首次 Apple 登录和昵称、头像设置后，点右上角“+”，扫描对方二维码或输入 16 位逐分 ID。对方接受后，双方分别在 Watch 开赛前选择彼此，并佩戴 Watch 记录比赛。比赛保存并同步到各自 iPhone 后，复盘页会在能唯一对应同一场比赛时显示对方已有的运动数据；没有佩戴 Watch 或缺少样本时不显示对应指标。这不是实时监测。
怎样停止对方查看或删除账号？
在球友详情解除好友后，对方不能继续读取你的比赛摘要。在“我的”页底部可删除逐分账号及云端比赛备份；本机比赛与 Apple 健康记录保留。退出登录不会撤回此前上传的摘要。
为什么没有心率或能量？
记分不会因为权限缺失而停用。请确认 Apple Watch 已允许逐分访问“健康”，并且表带贴合手腕；不完整或缺失的样本会显示为“无数据”，不会补成零。
“估计挥拍”和“典型手腕挥拍速度（估算）”是什么意思？
估计挥拍是手表戴在持拍手腕时检测到的挥拍形动作，不等于确认击中球。典型速度取本场可用事件窗口峰值手腕角速度的中位数，已观察最快取最大值，单位为 °/s。它们不是拍头速度、击球速度或球速，不换算为 km/h 或 m/s。走动、喝水、空挥或很小的网前动作都可能造成误计或漏计；旧记录和手动补记不会回算拍速。
iPhone 不在场边还能记分吗？
完成手机登录与资料设置，并连接手表后可以。Watch 会独立记分并本地排队保存；与 iPhone 重新连接后，会用同一比赛标识同步，避免生成重复场次。
双打能记录谁得分吗？
首版只记录我方或对方得分，不推断四个人中的具体得分者、发球员或站位。
怎样补充球友称呼或备注？
在 iPhone 的“场次”中打开比赛，点页面顶部的“补充资料”。称呼和备注会随比赛自动备份，不会改变 Watch 已记录的比分、心率或动作数据。
怎样恢复比赛？
联网登录原逐分账号后，比赛会从云端恢复到 iPhone；离线期间的新比赛会先保存在本机，重连后补传。Apple Health 中的 Workout 仍由“健康”App 管理。
Quick help in English
Add a friend and view Watch matches
Complete Sign in with Apple and nickname and avatar setup on iPhone. In Players, tap + and scan their QR code or enter their 16-character RallyTrace ID. After acceptance, both players select each other on Watch before starting and wear Watch during the match. Once both matches sync to iPhone, the review can show available opponent metrics when it can identify one matching match. A missing Watch or sample leaves that metric unavailable. These are not live readings.
Stop access or delete an account
Remove the friend to stop their access to your match summaries. Delete your RallyTrace account and cloud match backups at the bottom of Me; matches on this phone and Apple Health workouts remain. Signing out does not revoke previously uploaded summaries.
Heart rate or energy is missing
Scoring still works without Health access. Grant RallyTrace access on Apple Watch and wear the band snugly. Missing samples remain “No Data” and are never replaced with zero.
What are an estimated swing and Typical Wrist Swing Speed?
An estimated swing is swing-like motion detected on the racket wrist, not confirmed shuttle contact. Typical Wrist Swing Speed is the median peak wrist angular speed across usable event windows; Fastest Observed is the maximum. Both use °/s, not km/h or m/s, and are not racket-head, impact, or shuttle speed. Empty swings, daily movement, and small net shots can cause false positives or misses. Legacy records and manually added matches are not backfilled.
Can Watch score without iPhone nearby?
Yes, after signing in and completing your profile on iPhone and connecting your watch. Watch keeps the match locally and transfers the same match identifier after reconnecting so iPhone does not create duplicates.
Does doubles identify the scorer?
No. Version 1 records only which team won each point, not the individual player, server position, or rotation.
Add player labels or notes
Open a match in the iPhone Matches tab and choose Add Details near the top of the page. Labels and notes are backed up with the match and never overwrite Watch scores or sensor measurements.
Restore matches
Sign in to the same RallyTrace account while online to restore matches from the cloud. Offline matches stay on the phone until they can sync. Apple Health workouts remain managed by the Health app.
