一款只做日期这一件事的App 什么时候用? 想知道下个生日还有多少天,距离发薪日还有多久,某个纪念日已经过去多久。 需要农历看一眼今天是什么日子,是不是哪个传统节日快到了。 每年都要过的日子——生日、纪念日、体检、信用卡还款日——设一次,每年自动提醒。 单纯需要一个干净、没广告、打开就能看的日期。 主要功能 过去与未来 记录过去的重要日子,规划未来的安排。 重复日期与距离天数 这是它最特别的地方。设置一个重复日期(比如每年的结婚纪念日),它会自动显示距离下一次还有多少天。过去的显示“已过多少天”,未来的显示“还有多少天”——清清楚楚,不用自己算。 农历 一键切换到农历视图。传统节日、农历生日,不再需要翻老黄历。 提醒通知 给重要的日子设置提醒,到时间会通知你。不打扰,只提醒你该记住的事。 自定义背景色 选一个自己喜欢的颜色作为背景。是喜欢干净的白,还是护眼的暖黄,你自己决定。 自动深色模式 跟随手机系统,白天浅色、晚上深色。晚上在被窝里打开也不刺眼。 完全离线,保护隐私 不需要注册账号,不需要联网。所有数据只存在你的手机里。没有广告,没有第三方SDK,不会收集你的任何信息。你的日期只属于你自己。 谁适合用? 想干净利落看日期、不想被社交和广告打扰的人。 需要追踪纪念日、生日、发薪日等重复日期的人。 对隐私有要求,不想把个人数据传到云端的人。 为什么做极简日期? 市面上的日历要么太臃肿,要么广告满天飞。 我们只想做一个安安静静、把日期这件事做好的工具。没有多余的东西,但该有的都有。 隐私声明:https://gitee.com/mr-zhaoziming/all-app-web/blob/master/date_policy 使用条款:https://gitee.com/mr-zhaoziming/all-app-web/blob/master/date_support
