UsageWatch 使用帮助
在 iPhone、小组件和 Apple Watch 上查看 Codex 和 Claude Code 的额度、重置倒计时和上次更新时间。连接后，UsageWatch 会自动查询，无需电脑保持开机。
先看看示例
在欢迎页点“看看示例”，或到“设置 → 示例”打开“显示示例数据”。无需登录或连接 Codex、Claude，就能看看 App、小组件和 Apple Watch 的显示效果。
示例已标明，不代表你的真实额度。准备连接自己的账号时，请先关闭示例数据。
需要先登录吗？
不需要。你可以以游客身份连接账号、订阅或恢复订阅。UsageWatch 会在需要时准备游客账号。
通过 Apple 登录是可选的。它用于找回 UsageWatch 中已保存的连接和历史记录，不会代替这两个服务各自的登录，也不等于 App Store 的付款确认。
连接 Codex
- 在“设置”中点“连接 Codex”。
- 按页面提示，在 OpenAI 官方页面登录。
- 如果 OpenAI 要求输入代码，返回 UsageWatch 复制代码，再到 OpenAI 页面填写。
- 完成后返回 UsageWatch，等待连接成功并显示额度。
无需安装 Mac App，也无需与电脑配对。
连接 Claude
- 在“设置”中点“连接 Claude Code”。
- 在 Claude 官方页面登录，复制页面给出的代码。
- 返回 UsageWatch，粘贴这次登录的完整代码，再点“连接 Claude”。
- 等待连接完成。
如果登录已过期，请重新连接，并使用新页面给出的代码。密码只需填写在 Claude 官方页面，不要发给他人。
怎么看额度
Codex 显示剩余额度，Claude 显示已用额度。5 小时、7 天等周期分别显示，不会把不同服务或周期的额度加在一起。只显示服务实际提供的数据；没有显示，不代表额度为零。
到了页面标出的重置时间，也需要等服务返回新的额度数据，才能确认额度已恢复。
多久更新一次？
UsageWatch 在服务器上自动查询额度，不需要你开着电脑，也不会为了查询而向模型提问。
通常会在使用活跃时约每 15 分钟查询一次；额度长时间不变时，会减少查询。如果此前已减少查询，打开 iPhone App 会恢复较频繁的更新。你也可以点刷新，请求立即查询一次。
“已请求更新”不等于已经取得新数据。如果服务限制查询、已有查询正在进行或发生错误，更新可能需要等待。查询失败时，页面会保留上次的数据和时间，不会改成零。
Solo 和 Duo 有什么区别？
- Solo：监控 1 个账号，可选 Codex 或 Claude。美区首发价为每月 US$1.99，原价 US$6。
- Duo：同时监控 1 个 Codex 和 1 个 Claude 账号。美区首发价为每月 US$2.99，原价 US$10。
当前尚不支持同一服务的两个账号。其他地区使用当地币种，实际价格以 App Store 付款页为准。
首发优惠结束后，符合条件的现有订阅者可按已保留的优惠价续费。取消后重新订阅或切换方案时，以 Apple 显示的价格和规则为准。
既有账号的 7 天赠送
收费切换时，符合条件、尚未订阅的既有 UsageWatch 账号可获一次 7 天免费赠送。开始和结束时间以 App 显示为准；这段期限固定，不会因重新打开 App 而延长。
这是 UsageWatch 赠送的监控时间，不是 App Store 订阅，不会自动扣费。赠送期间仍可主动选择 Solo 或 Duo，并在 Apple 付款页确认。已有有效的 Apple 订阅时，按该订阅提供监控权限。Apple 的免费试用资格另行判断，不因这次赠送而改变。
赠送到期后，如无有效订阅，自动查询会暂停，旧免费连接占用的可释放监控名额会收回。暂停本身不会删除账号、已保存的登录信息或历史记录，原有的数据保留规则仍适用。要继续监控，请在 App 中订阅。付款前仍会检查实际可用的云端监控名额；如果容量确已用完，需要稍后再试。
App Store 免费试用与续费
符合资格的订阅可免费试用 7 天，是否符合资格由 Apple 确认。同一 Apple 账户在 Solo 和 Duo 中只能获得一次试用，升级不会再获得一次。
试用结束后，所选方案会按付款页显示的月费自动续费。若不想续费，请至少提前 24 小时在 App Store 的订阅管理中取消。取消后，可使用至当前有效期结束。
在 UsageWatch 的订阅页面可打开 App Store 订阅管理。删除 UsageWatch 或退出账号都不会取消订阅。
恢复订阅
换手机、重装 App 或更换 UsageWatch 账号后，可在订阅页面点“恢复订阅”，并按 App Store 提示使用购买时的 Apple 账户完成验证。无需先通过 Apple 登录 UsageWatch。
恢复订阅只恢复可同时监控的账号数量，不会带回原 UsageWatch 账号的连接和历史记录。如果订阅正在另一个 UsageWatch 账号使用，恢复后，那个账号中由此订阅提供的监控会暂停。
想找回原连接和历史记录，需要原账号已绑定 Apple 登录；请使用当时绑定的 Apple 账户登录 UsageWatch。
换手机时保留连接和记录
以游客身份使用时，可以稍后通过 Apple 登录并绑定当前账号，已有连接和记录会保留。建议在换手机、卸载 App 或退出游客账号之前完成绑定。
如果尚未绑定，且丢失了这台手机上的登录信息，就无法找回原游客账号，需要重新连接 Codex 和 Claude。恢复订阅也不会找回这些旧数据。
若 Apple 账户已经绑定另一个 UsageWatch 账号，App 会提示冲突。两个账号不会自动合并或覆盖。
小组件和 Apple Watch
在主屏幕或待机显示中添加 UsageWatch 小组件。Apple Watch 上可安装 UsageWatch，并添加到支持的表盘中。
如果小组件或手表没有显示额度，请先打开 iPhone 上的 UsageWatch，再到“设置”，点“已连接的设备”旁的“重新连接小组件和 Apple Watch”图标，然后等待更新。
小组件和 Apple Watch 的后台更新时间由系统安排，可能晚于 iPhone App。重复查看不会强制重新查询 Codex 或 Claude。
额度与重置提醒
在“设置”中打开额度不足提醒，并允许 UsageWatch 发送通知。取得最新额度数据且重置时间已知时，剩余额度降到 20% 和 10% 会提醒你。
也可以打开 Codex 重置提醒，在出现常规重置或备用重置公告时收到通知。公告来自 Codex Resets，不保证你的账号在同一时刻完成重置。
Codex 用量日历
Codex 额度页的日历会结合你的额度变化和重置公告，估算每天用了多少额度，并用表情显示当天的状态。点某一天可查看详情，也可查看单独的重置记录。
记录从成功取得额度数据后开始。缺少数据的日期不会补造记录；这些估算不代表工作时长。重新连接后会开始新的记录分段，断开 Codex 或删除 UsageWatch 账号会删除对应的个人记录。
额外用量余额与备用重置
如果 Codex 提供了相关信息，UsageWatch 会显示额外用量余额（Credits）和备用重置次数。它们与订阅额度分开显示，不会合并计算。
这里只展示余额和次数。购买额外用量或使用备用重置，请前往官方 Codex App。
断开连接、退出和删除账号
- 断开连接：停止查询该服务，删除已保存的连接数据；断开 Codex 也会删除对应的个人用量记录。再次使用需要重新连接。
- 退出账号：结束这台手机的登录，不会删除云端账号。游客请先阅读找回提醒。
- 删除账号：在“设置”的账号区域确认后，永久删除 UsageWatch 账号、连接、额度记录和设备访问权限。无法撤销，不会删除你的 OpenAI 或 Claude 账号。
以上操作都不会取消 App Store 订阅。若不想继续付费，请另行在 App Store 取消续费。
连接后会保存什么？
为自动查询额度，服务器会加密保存 Codex 和 Claude 的登录信息。这些信息并不是仅能查询额度的专用凭证。UsageWatch 将自己的操作限制为登录、查询额度和退出，不会为了测额度而发起模型任务。
断开连接可停止 UsageWatch 后续查询。它不保证服务商立即撤销此前签发的所有登录信息；如有需要，也可到 OpenAI 或 Claude 官方页面管理账号会话。

UsageWatch Help
Check Codex and Claude Code quotas, reset countdowns, and the last update time on iPhone, widgets, and Apple Watch. Once connected, UsageWatch checks for updates automatically. You don’t need to keep a computer running.
Try it with sample data
Choose Explore sample data on the welcome screen, or turn on Show sample data in Settings → Sample data. Preview the app, widgets, and Apple Watch without signing in or connecting Codex or Claude.
Samples are clearly labeled and don’t show your real quota. Turn sample data off when you’re ready to connect your own accounts.
Do I need to sign in?
No. You can connect accounts, subscribe, and restore a subscription as a guest. UsageWatch prepares a guest account when needed.
Sign in with Apple is optional. It helps you recover the connections and history saved in UsageWatch. You still sign in to each service separately, and App Store payment confirmation is a separate step.
Connect Codex
- In Settings, tap Connect Codex.
- Follow the instructions to sign in on OpenAI’s official page.
- If OpenAI asks for a code, return to UsageWatch to copy it, then enter it on the OpenAI page.
- Return to UsageWatch and wait for the connection and quota to appear.
No Mac app or computer pairing is needed.
Connect Claude
- In Settings, tap Connect Claude Code.
- Sign in on Claude’s official page and copy the code it gives you.
- Return to UsageWatch, paste the complete code from this sign-in attempt, and tap Connect Claude.
- Wait for the connection to finish.
If the sign-in has expired, start a new connection and use the new code. Enter your password only on Claude’s official page; don’t share it with anyone.
Read your quota
Codex shows quota remaining; Claude shows quota used. Periods such as 5 hours and 7 days are shown separately. Quota from different services or periods isn’t added together. UsageWatch displays only the information each service reports; a missing value doesn’t mean zero quota.
When a reset time arrives, a new update from the service is still needed to confirm that quota has reset.
When does quota update?
UsageWatch checks your quota on the server. Your computer can be off, and checks don’t send prompts to a model.
Checks usually run about every 15 minutes while usage is active, and less often when quota stays unchanged. If checks have slowed down, opening the iPhone app brings back more frequent updates. Tap Refresh to request a check now.
An update request doesn’t mean new data has arrived. A service limit, a check already in progress, or an error can delay the update. If a check fails, UsageWatch keeps the previous data and its timestamp instead of showing zero.
Choose Solo or Duo
- Solo monitors one account: Codex or Claude. The US launch price is US$1.99 per month (original price US$6).
- Duo monitors one Codex account and one Claude account together. The US launch price is US$2.99 per month (original price US$10).
Two accounts from the same service aren’t supported yet. Other regions use local currency. The App Store payment sheet shows the price you’ll pay.
When the launch offer ends, eligible existing subscribers can keep their preserved renewal price. If you cancel and resubscribe or change plans, Apple’s displayed price and rules apply.
Seven free days for existing accounts
When paid access starts, eligible existing UsageWatch accounts without a subscription can receive seven free days once. Check the app for the start and end times. This is a fixed period; reopening the app does not extend it.
These free days are a gift of monitoring time from UsageWatch, not an App Store subscription. They do not renew or charge you automatically. You can still choose Solo or Duo during this period and confirm a subscription through Apple. If you already have an active Apple subscription, its monitoring access takes priority. Apple determines free-trial eligibility separately; this gift does not change it.
When the gift ends, automatic quota checks pause if you have no active subscription. Releasable monitoring places held for old free connections are returned to the available pool. Pausing itself does not delete your account, saved sign-in information, or history; the existing data-retention rules still apply. Subscribe in the app to continue monitoring. Available cloud-monitoring capacity is still checked before purchase. If it is full, you will need to try again later.
App Store free trial and renewal
Eligible subscribers get a 7-day free trial. Apple determines eligibility. Each Apple Account can receive one trial across Solo and Duo; upgrading doesn’t start another trial.
After the trial, your chosen plan renews automatically at the monthly price shown before confirmation. To stop renewal, cancel through App Store subscription settings at least 24 hours before it renews. Access continues until the current period ends.
You can open App Store subscription settings from UsageWatch’s subscription page. Deleting the app or signing out doesn’t cancel your subscription.
Restore a subscription
After changing phones, reinstalling the app, or switching UsageWatch accounts, tap Restore subscription on the subscription page. Follow the App Store prompts using the Apple Account that purchased the subscription. You don’t need to sign in to UsageWatch with Apple first.
Restoring a subscription restores the number of accounts you can monitor. It doesn’t bring back the previous UsageWatch account’s connections or history. If the subscription is being used by another UsageWatch account, restoring it pauses the monitors it paid for on that account.
To recover the original connections and history, the original account must already have been linked to Sign in with Apple. Sign in to UsageWatch with the Apple Account used for that link.
Keep your connections when you change phones
You can link your current guest account to Sign in with Apple later and keep its connections and history. Do this before changing phones, deleting the app, or signing out of a guest account.
If you haven’t linked Apple and lose this phone’s sign-in information, the original guest account can’t be recovered. You’ll need to reconnect Codex and Claude. Restoring a subscription won’t recover that old data.
If the Apple Account is already linked to another UsageWatch account, the app reports a conflict. The two accounts won’t be merged or overwritten.
Widgets and Apple Watch
Add UsageWatch widgets to your Home Screen or StandBy. Install UsageWatch on Apple Watch and add it to a compatible watch face.
If a widget or your watch shows no quota, open UsageWatch on iPhone. In Settings, tap the Reconnect widgets and Apple Watch icon beside Connected devices, then allow time for it to update.
The system schedules background updates for widgets and Apple Watch, so they may update later than the iPhone app. Repeatedly checking them doesn’t force a new Codex or Claude query.
Quota and reset alerts
Turn on low-quota alerts in Settings and allow UsageWatch notifications. When fresh quota data and a reset time are available, you’ll be notified at 20% and 10% remaining.
You can also enable Codex reset alerts for announcements of regular or banked resets. Announcements come from Codex Resets and don’t guarantee that your account resets at the same time.
Codex usage calendar
The calendar on the Codex quota page combines your quota changes with reset announcements to estimate daily usage and show an emoji for the day. Tap a date for details, or open the reset history.
History starts when quota data is successfully collected. Missing days aren’t filled in, and estimates don’t measure working hours. Reconnecting starts a separate history period. Disconnecting Codex or deleting your UsageWatch account deletes the related personal history.
Credits and banked resets
When Codex provides the information, UsageWatch shows your extra-usage balance (Credits) and available banked resets. These are separate from subscription quota and aren’t added together.
UsageWatch only displays the balance and reset count. Go to the official Codex app to buy extra usage or use a banked reset.
Disconnect, sign out, or delete your account
- Disconnect: Stops quota checks for that service and deletes its saved connection data. Disconnecting Codex also deletes its related personal usage history. You’ll need to reconnect to use it again.
- Sign out: Ends sign-in on this phone without deleting the cloud account. Guests should read the recovery warning first.
- Delete account: Confirm deletion in the account section of Settings to permanently remove your UsageWatch account, connections, quota history, and device access. This can’t be undone. It doesn’t delete your OpenAI or Claude account.
None of these actions cancels an App Store subscription. Cancel renewal separately in the App Store to stop future charges.
How are connected accounts used?
To check quota automatically, the server stores encrypted Codex and Claude sign-in information. This isn’t a special grant that can only read quota. UsageWatch limits its own actions to signing in, checking quota, and signing out; it doesn’t start model tasks to measure quota.
Disconnecting stops future UsageWatch checks. It doesn’t guarantee that the provider immediately invalidates every previously issued sign-in credential. You can also manage sessions on OpenAI’s or Claude’s official website.
