支持与常见问题Support & FAQ
快速上手Getting started
- 打开 App,主界面即显示与系统同步的毫秒级时钟。 Open the app — the main screen shows the millisecond clock, synced to system time.
- 点击「开启跨 App 悬浮窗」,时钟会变成一个画中画小窗。 Tap "开启跨 App 悬浮窗" (Start floating window) and the clock becomes a Picture-in-Picture window.
- 切换到任何其他 App(购物、抢票……),小窗始终悬浮在最上层。 Switch to any other app (shopping, ticketing…) — the window stays floating on top.
- 拖动小窗四角可移动位置,双指捏合可调整大小;再次回到 App 点同一按钮即可关闭。 Drag the window to move it, pinch to resize; return to the app and tap the same button to close it.
常见问题FAQ
悬浮窗按钮是灰色的,点不了?The floating-window button is grayed out?
悬浮窗依赖系统的"画中画"能力。请检查:设置 → 通用 → 画中画 是否已开启;另外 iOS 模拟器不支持画中画,请在真机上使用。 The floating window relies on the system Picture-in-Picture capability. Check Settings → General → Picture in Picture is enabled. Note the iOS Simulator does not support PiP — use a real device.
时钟准吗?和北京时间差多少?How accurate is the clock?
App 直接读取 iPhone 的系统时间,精确到毫秒显示。系统时间本身由 iOS 通过网络时间服务自动校准——通常与标准时间的偏差在几十毫秒以内。App 自身不做任何时间修改。 The app reads the iPhone's system time directly and displays it to the millisecond. iOS itself keeps system time calibrated via network time services — typically within tens of milliseconds of the reference. The app never alters time.
为什么后台还能走字?会耗很多电吗?Why does it keep ticking in the background? Battery impact?
悬浮窗通过系统画中画通道渲染(每秒 30 帧的小画面),这是 iOS 的原生机制,功耗与播放一个小视频窗口相当。不需要悬浮窗时关掉它即可。 The floating window renders through the system PiP pipeline (a small 30 fps surface) — a native iOS mechanism with power draw comparable to a small video window. Close it whenever you don't need it.
时钟卡片被我拖到边上了,怎么复位?I dragged the clock card away — how do I reset it?
双击时钟卡片即可回到屏幕中央。卡片永远不会被完全拖出屏幕。 Double-tap the clock card to snap it back to center. The card can never be dragged fully off-screen.
App 会播放声音吗?为什么申请了音频后台模式?Does the app play audio? Why the audio background mode?
不播放任何声音。"音频、AirPlay 与画中画"是 iOS 中承载画中画功能的官方后台模式,App 以静音、可混音的方式使用它,不会打断你正在听的音乐或播客。 It plays no sound. "Audio, AirPlay, and Picture in Picture" is the official iOS background mode that hosts PiP; the app uses it silently in mix-with-others mode, so your music or podcasts keep playing untouched.
支持哪些设备和系统?Which devices and OS versions are supported?
iPhone 与 iPad,iOS/iPadOS 18.0 及以上。 iPhone and iPad, iOS/iPadOS 18.0 or later.
你们收集我的数据吗?Do you collect my data?
不收集。App 完全不联网,没有广告和统计。详见隐私政策。 No. The app never connects to the network and has no ads or analytics. See the Privacy Policy.
