时格,把"时间"做成能被看见、会被耗尽的东西。 倒数日、纪念日、人生进度——不只是一个数字,而是一片会被慢慢填满、慢慢熄灭的格子。还剩多少,已过去多少,一眼就能感受到。 — 签名:时间格子 — 每一格是一段时间(天 / 周 / 月,随事件自动选)。已过去的填满,剩下的留白。在事件详情页看到全分辨率的格栅,在"人生进度"页把一生画成一格格的周——你会真切地看见时间在流逝。 — 锁屏与桌面小组件 — 单事件、事件列表、人生进度,多种尺寸,主屏与锁屏都能放。把最在意的日子摆在每天都会看到的地方。可为事件配一张封面照片,做成桌面上的"照片倒数"。 — Apple Watch — 把最在意的日子放上表盘:多种表盘组件尺寸任选,抬腕就知道还剩多少天。手表上也能翻看日子详情;创建和编辑仍在 iPhone 上完成。 — 为中文场景而做 — 支持农历重复:生日、忌日、长辈寿辰、传统节日,按农历自动算下一次。显示单位可切天 / 周 / 月 / 年,或"5年3个月20天"式的组合。分类、置顶、搜索、排序,事件再多也清楚。 — 每天值得打开一次 — "今日"汇总今天到点与临近的事、今年已过百分比、本周又熄灭一格。临近自动提醒,可设当天与提前多档。 — 一次买断,数据是你的 — 免费版可记 5 个事件并使用全部同步。买断解锁无限事件、完整样式、自定义强调色与人生进度高级视图——一次付费,永久使用,不是订阅。 所有数据只存在你的设备与你自己的 iCloud,App 不收集任何信息,跨设备同步免费。 把值得期待或珍惜的日子放进来,让时间被看见。
