言己可能是目前最简单的微博备份工具。 一键备份所有原创及转发的微博及配图（包括自己可见，好友圈可见的微博）。在备份过程中将会闪现过往，犹如看到自己的人生里一幕幕黑历史，还是一生中急速流走的最美好的时光？ 一键备份所有已备份微博的评论。这些都是朋友间互相探讨的记忆。 所有备份下来的微博都是离线保存在自己设备里。即使微博官网上的微博删除了，在言己里依然能读到这些微博。 如果你担心在言己里保存还不够安全的话，还可以使用导出文件的功能将微博备份导出成文本文件或图文并茂的PDF文件，传到电脑或云端。这样即使没有言己，备份的微博还会以PDF文件等形式阅读。 言己的备份微博检索功能，速度快，数据全，不需要流量。对于将微博当作日记或资料用的用户会更加体会到它的强大。 目前，言己还只能备份自己的微博，不能备份他人的微博，也不能备份视频。 注意事项 第一次使用时点击“备份”时需要登录微博。如果在点击登录时没有反应，可以到Safari中打开weibo.cn，测试一下是否能登录上微博官网。 第一次备份微博的数量很大，可以备份一部分暂停，有空闲就继续备份。整个过程不影响微博正常使用。 如果担心安全问题，可以在登录后修改微博密码。 新增功能：本地设备上备份的微博与Apple iCloud同步，云端保存一份备份的微博。 有问题请@wfg西游，谢谢！
