购买与付款
美国区下载价格为 US$0.99，一次性购买，没有 App 内购买或订阅。其他地区以 App Store 显示的当地价格为准；是否已上架以当地 App Store 为准。App Store 付款与退款由 Apple 处理，可访问 Apple 报告问题；退款资格由 Apple 决定。重新下载已购买的应用不等于恢复本机手记。
开始使用
iPhone 需要 iOS 17 或更新系统，Apple Watch 需要 watchOS 10 或更新系统。在 iPhone 打开缓息，可使用“此刻”“节律”“手记”。需要查看健康记录时，选择“连接 Apple 健康”并按系统提示选择权限。无需注册账号；不连接健康也可以写手记或进行一分钟呼吸节拍。
在 Apple Watch 上打开缓息，按需连接本机健康记录。只请求读取 HRV（SDNN）、静息心率与心率，不向 Apple 健康写入数据。健康展示需要设备上已经存在可读取记录，应用本身不启动连续心率或 HRV 测量。手表与手机独立读取各自可见的记录，两端结果可能不同。
为什么暂时没有比较结果
个人参考需要过去 28 天内至少 7 个不同历史日、合计 14 条有效 HRV；今天至少需要 2 条，且最新记录在今天、距今不超过 6 小时。条件不足时会显示等待、积累或过时提示。
没有数据可能是没有记录，也可能是未允许读取。应用不能据此判断你是否拒绝了权限。可检查系统健康访问设置，再回到应用刷新。缓息不把缺失填成零，也不自动生成示例读数。
如何开启或关闭手表提醒
请直接在 Apple Watch 上打开缓息，在首次提示或“通知设置”中选择“开启通知”，并由你决定是否允许系统通知。iPhone 的说明页不代表手表已授权，iPhone 也不会发送状态提醒。
提醒需满足个人参考条件，且是开启后测得、测量发生在今天、距处理时不超过 1 小时的新 HRV。提醒使用最近一次有效 HRV 与个人参考比较，不等待今天第二条记录。默认仅状态变化时提醒，最短间隔为 15 分钟，可选 15、30、60 或 120 分钟；默认启用 22:00–08:00 安静时段。间隔内的新变化会在下次真实更新时重新判断最新且仍新鲜的记录，不补发旧通知。系统采样、后台调度、专注模式及通知设置都可能影响显示，不保证每条记录都有提醒。
没有提醒不等于开关自动关闭。请先查看手表通知设置与健康参考是否就绪。关闭时，在手表“通知设置”选择关闭并确认；系统中还可管理通知权限和预览。系统接受通知也不代表你一定看到了通知。
压力估计、HRV 数值与动物角色
提醒标题为“压力估计：偏高 / 一般 / 偏低”，卡片显示同次测量的 HRV 数值（ms）与简短测量时间。HRV 数值不是压力分数。这是基于 HRV 与个人基线的参考估计，算法未经过压力预测验证，非医学诊断；运动、睡眠、饮酒等也影响 HRV。
最近 HRV 低于个人参考的 80% 对应估计偏高，高于 120% 对应偏低，其余（含边界）对应一般；不是心理压力的实测值。在手表“通知设置”中可选择猫、兔子、狐狸或水豚，默认猫。角色只改变外观，不改变权限、提醒开关、间隔或个人参考。已经提交的提醒保留当时的角色与原测量；旧回执缺少 HRV 时不会补造数值。系统可能使用自己的通知样式。
手记、删除与换机
在“手记”中新增感受、文字与标签，删除已有记录需确认。手记只在本机保存，不与手表或其他手机同步。本版没有导入导出、应用自己的云备份或恢复服务。卸载会失去本机手记，不能承诺换机后恢复。
健康查询在设备上处理。为保持提醒与原测量一致，待处理和最近已接受的回执在本机有限保存该次 HRV、标识、时间、比较类别和角色，不建立健康数值历史库，不发送给开发者或第三方。详细存储、备份与删除边界请查看隐私政策。
呼吸练习与使用边界
一分钟呼吸节拍可以随时停止；4 秒吸气、6 秒呼气只是建议，自然呼吸即可。若头晕或不适，请停止并恢复自然呼吸。练习不向 Apple 健康写入数据，也不保证改变健康指标。
缓息不提供经验证的心理压力测量、疾病评分、诊断、治疗或紧急报警，不代替医生意见，也不是连续或实时监测工具。持续不适或作出医疗决定前，请咨询医生。

Purchase and payment
The US App Store price is US$0.99, paid upfront, with no in-app purchases or subscriptions. Other regions use the local price shown by the App Store; availability depends on your local storefront. Apple handles payment and refund requests through Report a Problem and determines refund eligibility. Redownloading a purchased app does not restore local journal entries.
Getting started
Huanxi requires iOS 17 or later on iPhone and watchOS 10 or later on Apple Watch. On iPhone, use the overview, rhythms and journal sections. Choose to connect Apple Health when you want to see health readings, then select permissions in the system prompt. No account is needed. The journal and one-minute breathing guidance work without health access.
Open Huanxi on Apple Watch and connect its local health records if you wish. The app requests read access only to HRV (SDNN), resting heart rate and heart rate, and does not write to Apple Health. Health views depend on existing readable records; Huanxi does not start continuous heart rate or HRV measurement. Phone and Watch query their own available records and may show different results.
Why is there no comparison yet?
The personal reference requires at least 14 valid HRV readings across 7 distinct historical days in the preceding 28 days. The daily comparison also requires at least 2 readings today, with the latest measured today and no more than 6 hours old. When these conditions are not met, the app shows that it is waiting, gathering a reference or using outdated data.
No data can mean either no records or no read permission; the app cannot determine from this alone whether you denied access. Check system Health access settings, then return and refresh. Huanxi does not replace missing data with zeros or invent example readings.
Turn Watch reminders on or off
Open Huanxi directly on Apple Watch and choose to enable reminders in the first-run prompt or notification settings. You decide whether to allow the system permission request. The iPhone guide does not grant Watch permission, and the iPhone does not produce status reminders.
A reminder needs an eligible personal reference and a new HRV reading measured after you enabled reminders, on the current day, and no more than 1 hour before processing. It compares the latest valid reading with your personal reference without waiting for a second reading today. By default, only a change of state can trigger a reminder. The minimum interval defaults to 15 minutes; 15, 30, 60 and 120 minutes are available. Quiet hours default to 22:00–08:00. After an interval, a real update reassesses the latest still-fresh reading; old reminders are not replayed. System sampling, background scheduling, Focus and notification settings affect visibility, so not every reading produces a visible alert.
No alert does not mean the switch turned itself off. Check Watch notification settings and whether the personal reference is ready. To stop reminders, turn them off in the Watch app and confirm; system settings also control permission and previews. System acceptance of a notification does not prove that you saw it.
Stress estimates, HRV values and animal characters
Reminder titles show a higher, usual or lower stress estimate. The card includes the original reading's HRV value in milliseconds and a compact measurement time. An HRV value is not a stress score. The estimate compares HRV with your personal baseline; the algorithm has not been validated for stress prediction and is not a medical diagnosis. Exercise, sleep, alcohol and other factors also affect HRV.
A latest HRV below 80% of the personal reference maps to a higher estimate; above 120% maps to lower; the remaining range, including both boundaries, maps to usual. This is not a measured psychological state. In Watch notification settings, choose a cat, rabbit, fox or capybara; cat is the default. The animal is cosmetic and does not change permissions, reminder preferences, intervals or your personal reference. Already submitted reminders keep the original animal and measurement; missing legacy HRV values are not invented. The system may use its own notification presentation.
Journal, deletion and changing devices
Save feelings, text and tags in the journal; deletion requires confirmation. Entries stay on the iPhone and do not sync to the Watch or other phones. This version has no import/export, developer-operated cloud backup or recovery service. Uninstalling loses local entries, and recovery on a new device is not promised.
Health queries are processed on-device. To preserve the link between a reminder and its original measurement, pending and most recently accepted receipts locally retain a bounded record of that HRV value, identifier, times, comparison category and animal. The app does not create a history of health values or send them to the developer or third parties. See the English privacy policy for storage, backup and deletion details.
Breathing guidance and limits
You may stop the one-minute breathing guide at any time. The suggested 4-second inhale and 6-second exhale are optional; breathe naturally. Stop and return to normal breathing if you feel dizzy or uncomfortable. The exercise does not write to Apple Health or guarantee a change in any health metric.
Huanxi does not provide validated psychological stress measurement, disease scores, diagnosis, treatment or emergency alerts. It is not continuous or real-time monitoring and does not replace medical advice. Consult a doctor if symptoms persist or before making medical decisions.
