BCTO是一款由博通光电有限公司开发的用于智能终端的天文软件。 BCTO分为两部分: 1. 电子星图部分。电子星图模拟一个实时3D的星空环境,调用智能终端内部传感器计算出用户当前的手机视角所能看到的星空天象。电子星图内置多达30000颗天体数据,包括太阳系数据,88个星座数据,IC数据,Messier数据,NGC数据等等。 2. 控制部分。可以蓝牙空中接口链接到博通公司生产的无线版本的天文望远镜,实现对望远镜的无线操作。用户可以在BCTO上对望远镜执行星体校准,转动控制,搜索和跟踪天体等多种操控功能。 另外可以配合电子星图,通过可视化选择星体后实时搜索跟踪天体目标。

Choose when to end your bedtime call. SleepCall connects to Apple Shortcuts to schedule your call to end. Sleep log · Statistics Log your bedtime and wake-up time, and set morning reminders for each day of the week. View your sleep calendar, 7-day average, and consecutive and total days of call-timer use. Sleep and actual call duration are not measured automatically. With Screen Time permission, choose one app to block on a daily schedule, with or without PRO. After an 8-second breathing exercise, you may allow 1–60 minutes of temporary access. When it expires, blocking resumes until the daily blocking period ends. Free features • 15-minute, 30-minute and 1-hour timers • Lock Screen and Home Screen widgets, Control Center and Siri • Vibration before the timer ends, cancellation and recovery guidance Choose your own time with PRO (1 minute–12 hours) Set a custom duration or end time, change the time during a timer, or extend it by 30 minutes. PRO is a monthly subscription that renews automatically. The price is shown on the purchase screen. You can cancel through your Apple Account's subscription management. Existing lifetime purchases remain valid and can be restored using Restore Purchases. How it works One call timer uses a shortcut that turns Airplane Mode on and Wi-Fi off. If the end of the call is detected, connectivity may return early; otherwise, within 60 seconds, it turns Airplane Mode off and Wi-Fi on. Results vary by app and device. Use the in-app 10-second test before relying on it. Connect the shortcut before your first timer. Before starting, check that Airplane Mode is off, cellular data is on and Wi-Fi is on. The app cannot read your network settings and does not automatically restore your previous settings. If the shortcut stops, turn Airplane Mode off and turn cellular data and Wi-Fi on in Settings. Email the developer from Settings → Help. Timers and settings stay on this iPhone. We do not collect your contacts, call content or phone numbers. Requires iOS 27.0 or later.
