# Livetime

> Livetime（在 Google Play 上名为 LivetimeOs）是一款没有广告的 Android 主屏幕，取代手机自带的主屏幕，帮助减少屏幕使用时间、保持专注、提高效率。仅支持 Android：https://play.google.com/store/apps/details?id=com.livetimeos.launcher

Livetime 不是又一个屏蔽类应用，而是手机的主屏幕：你第一眼看到的地方，也是通往应用的唯一入口。应用通过输入名称打开；习惯性应用（邮箱）每次打开都要等待，且等待越来越长；易上瘾应用（Instagram、TikTok）在进入前会问你想用几分钟，限额可选宽松、灵活或严格；Instagram 和 YouTube 以轻量界面打开，没有 Reels、Shorts 和推荐；专注、运动和睡眠模式只保留当下的应用，难度可选简单、适中或困难；只统计在分心应用上花的时间。此外还有安装时的评估、网站屏蔽、记录想法的第二大脑、番茄钟、任务和习惯。

Livetime 由法国学生 Emile Clement 开发，此前他花了两年时间尝试其他方法（屏蔽应用、黑白屏幕、删除社交媒体、极简手机）。截至 2026 年 10 月，Google Play 下载量超过 100；一项关于所有用户屏幕使用时间变化的研究正在进行。本站此版本为简体中文；应用和网站提供 25 种语言（列表见本文件末尾）。Livetime 不支持 iPhone，不会删除任何应用，无障碍权限仅用于屏蔽网站（可选）：它只读取浏览器中显示的网址。
