首次创建闹钟时，请在系统弹窗中允许访问。你也可以打开 iPhone“设置”，搜索 FitAlarm 并检查可用权限。AlarmKit 权限入口可能因 iOS 版本而不同；若未出现，请确认设备已升级到 iOS 26 或更高版本，然后重启 FitAlarm 并再次创建闹钟。

前往“设置 → 隐私与安全性 → 相机”，确认 FitAlarm 已开启。彻底退出并重新打开应用，关闭其他正在使用摄像头的应用，并确认设备不是处于屏幕录制限制或家长控制限制下。仍未恢复时，请重启 iPhone。

把手机稳定放置，让摄像头能看到头部、肩膀、手臂和髋部的大致位置。保持光线充足，避免逆光和宽松衣物完全遮挡关节。FitAlarm 的目标是确认你已经行动，而不是评判标准姿势；完整地做一次向下再向上通常更容易被识别。

确认闹钟仍为开启状态，设备有足够电量并已授予所需权限。系统更新、设备关机、异常系统状态或权限变化都可能影响闹钟。请先设置一个几分钟后的测试闹钟验证。不要将 FitAlarm 作为安全关键事务的唯一提醒。

在挑战界面使用紧急退出入口并按屏幕提示操作。该设计用于身体不适、环境不安全或必须立即安静的情况；使用后可能中断本次连续记录。

打开 iPhone“设置 → Apple 账户 → 订阅 → FitAlarm”，选择取消订阅。请在当前订阅期或免费试用结束至少 24 小时前操作。删除应用不会取消订阅。

确认设备登录的是购买时使用的 Apple 账户，然后在 FitAlarm 付费页面选择“恢复购买”。等待 App Store 返回结果后重新打开应用。如果 Apple 显示已付款但仍无法恢复，请在联系支持时附上产品名称和购买日期，不要发送完整付款卡信息。

购买和退款由 Apple 处理。请访问 reportaproblem.apple.com，登录购买所用的 Apple 账户并按页面提示提交申请。

当前版本需要能够运行 iOS 26 或更高版本并支持所需系统框架的 iPhone。动作挑战还需要可用的摄像头权限。

不会。动作识别通过 Apple Vision 在设备上进行，摄像头画面和视频不会由我们保存或上传。详细说明请查看隐私政策。

Allow access in the system prompt when you first create an alarm. You can also open iPhone Settings, search for FitAlarm, and review the available permissions. The AlarmKit permission location may vary by iOS release. If it does not appear, confirm that the device runs iOS 26 or later, restart FitAlarm, and try creating an alarm again.

Go to Settings → Privacy & Security → Camera and make sure FitAlarm is enabled. Fully close and reopen the app, close other apps using the camera, and check for Screen Time or parental-control restrictions. Restart the iPhone if the camera still does not recover.

Place the phone securely so the camera can generally see your head, shoulders, arms, and hips. Use adequate light, avoid strong backlighting, and avoid clothing that fully hides joint positions. FitAlarm is meant to confirm that you moved, not grade perfect form. A complete down-and-up movement is usually easiest to recognize.

Confirm the alarm is enabled, the device has enough power, and required permissions remain granted. System updates, a powered-off device, unusual system conditions, or permission changes can affect alarms. Set a test alarm a few minutes ahead first. Do not use FitAlarm as the only reminder for a safety-critical commitment.

Use the emergency exit on the challenge screen and follow the on-screen instruction. It is intended for discomfort, an unsafe environment, or a situation requiring immediate silence. Using it may interrupt the current streak.

Open iPhone Settings → Apple Account → Subscriptions → FitAlarm, then choose Cancel Subscription. Cancel at least 24 hours before the current subscription or free-trial period ends. Deleting the app does not cancel a subscription.

Confirm that the device uses the same Apple Account used for the purchase, then select Restore Purchases on the FitAlarm paywall. Reopen the app after the App Store returns a result. If Apple shows a completed payment and restore still fails, include the product name and purchase date when contacting support. Do not send full payment-card details.

Apple processes purchases and refunds. Visit reportaproblem.apple.com, sign in with the Apple Account used for the purchase, and follow Apple's instructions.

The current version requires an iPhone capable of running iOS 26 or later and the required system frameworks. Movement challenges also require camera access.

No. Exercise recognition uses Apple Vision on the device. We do not save or upload camera footage or video. See the Privacy Policy for details.
