Cairn 司候
在等的日子，还剩多少；走过的日子，已经多久。
一个完全在你设备上运行的日子计数器。
How long until the day you're waiting for — and how long since the one you're counting from.
A day counter that runs entirely on your device.

它是什么
What it is
两个方向都算
Counts both ways
倒数报的是还剩多少，进度条像电量条——实心是还没花掉的那部分，从满走到空。纪念日则往上数，100 天、365 天、520 天、1000 天，走过的里程碑一列都留着。
A countdown tells you what's left, on a bar that reads like a battery — the filled part is the time you haven't spent yet. Anniversaries count up instead, and every milestone you pass — 100 days, 365, 1,000 — stays on the list.
一页配得完
Everything on one page
重复规则、多条提醒、每日汇总、农历、进度样式都在同一页。时区锁在事件上——飞一趟美国，家里那件事的数字不会跟着跳。
Repeat rules, multiple reminders, a daily digest, lunar dates, and progress styles all live in one editor. The time zone is pinned to the event, so flying across the world doesn't make the number jump.
数据在你手里
Your data stays yours
没有服务器、没有账号、没有广告、没有分析 SDK。数据存在设备上，同步走的是你自己 Apple 账户的 iCloud 私有库，随时可以导出一份完整的 JSON 备份。
No servers, no sign-up, no ads, no analytics SDKs. Your events live on your device; syncing goes through the iCloud private database of your own Apple Account, and you can export a complete JSON backup at any time.
摆到你看得见的地方
Where you'll actually see it
日子计数器的价值不在打开 App 的那一刻，而在你没打开的时候还能看见。
A day counter earns its keep when you're not looking at the app.
| 在哪儿 | 看到什么 |
|---|---|
| 主屏与锁屏小组件 | 单个事件、近期列表、年度分布图，尺寸各有一套排版 |
| 灵动岛与实时活动 | 临近的那件事一路顶在屏幕上 |
| Apple Watch | 独立 App 与表盘复杂功能，事件改动由 iPhone 直接推过去 |
| 通知 | 按事件排的提醒，外加每天固定时刻的一条汇总 |
| 时间线 | 一整年十二个月摊开：哪个月最挤、今年还剩多少 |
| Where | What you get |
|---|---|
| Home & Lock Screen widgets | A single event, an upcoming list, or the year's distribution — laid out per size |
| Dynamic Island & Live Activities | The nearest event, pinned to the screen as it approaches |
| Apple Watch | A standalone app and watch face complications, pushed straight from your iPhone |
| Notifications | Per-event reminders, plus one digest at a fixed time each day |
| Timeline | All twelve months at once — which one is crowded, how much of the year is left |
从已有的日子开始
Start from days you already have
可以从系统日历导入日程、从通讯录导入生日（生日会建成每年重复的事件）。两种导入都只读——Cairn 不会新增、修改或删除你的任何日历事件与联系人，读到的内容也只留在设备上。导入一律是追加而不是替换。
You can import events from your system calendar and birthdays from your contacts (birthdays become yearly repeating events). Both are read-only — Cairn never creates, edits, or deletes a calendar event or a contact, and what it reads stays on your device. Importing always appends rather than replaces.
