运作方式

三步，全部在
这台手机上完成。

不需要注册账号，也不需要联网。

1. 扫描桌面

   摄像头识别面前的平面，虚拟监狱落在你打算放手机的位置。这一步用到增强现实，画面只在设备上实时处理。

2. 手机入狱

   把手机放进去，服刑计时开始。经你授权后，其他应用在服刑期间被系统暂时屏蔽。

3. 服满出狱

   时间到了自动解除限制，本次记录写入本机。中途拿起手机会触发越狱警告，你也可以随时提前释放。

How it works

Three steps, all of
them on the phone.

No account to create, no network connection needed.

1. Scan the desk

   The camera finds the surface in front of you and the jail lands where you plan to set the phone down. This step uses augmented reality, and the video is processed on the device in real time.

2. Lock it up

   Put the phone inside and the sentence begins. Once you grant permission, the system holds other apps back for the duration.

3. Serve it out

   Restrictions lift on their own when time is up, and the session is written to local storage. Pick the phone up early and you get a jailbreak warning — you can also release yourself at any point.

功能

一座监狱，
该有的都有。

• 增强现实放置

  虚拟监狱落在真实桌面上，服刑对象是眼前这台具体的手机，而非屏幕里的一个计时器。

• 拿起检测

  运动与方向传感器判断手机是否被拿起或移动，中断时以震动与提示发出越狱警告。

• 应用屏蔽

  经授权后借助系统的屏幕使用时间能力，在服刑期间暂时限制其他应用，结束后自动解除。

• 记录与趋势

  连续专注天数、每日与每周统计，全部由本机记录计算，不上传任何服务器。

  英语、简体中文、繁体中文、日语、韩语、西班牙语、法语、德语、巴西葡语、俄语、意大利语、印尼语。

  不提供注册与登录，不含广告、行为分析或云端同步组件。

Features

One jail,
fully equipped.

• Augmented reality placement

  The jail sits on your actual desk, so what serves the sentence is the specific phone in front of you — not a timer behind glass.

• Pick-up detection

  Motion and orientation sensors tell whether the phone has been lifted or moved, and a jailbreak warning follows through vibration and an on-screen prompt.

• App restrictions

  With your permission, the system's Screen Time capability holds other apps back for the length of a session and releases them afterwards.

• Records and trends

  Streaks, daily and weekly figures — all computed from records kept on the device. Nothing is uploaded.

• Twelve languages

  English, Simplified and Traditional Chinese, Japanese, Korean, Spanish, French, German, Brazilian Portuguese, Russian, Italian, and Indonesian.

• No account, no ads

  There is no sign-up or sign-in, and no advertising, behavioural analytics, or cloud-sync component.
