「须臾」是一个基于一万小时定律的项目时间计时器，它帮助您规划和追踪投入在各个项目或技能上面的花费时间。譬如，你可以追踪在「英语」上刻意练习了多久，在「古典音乐」上投入了多长时间。「须臾」既是一个时间累加器，也是一个关于时间的日记。

「须臾」支持两种添加时间的方式：
1. 正向计时器；
2. 直接添加一段时间记录；

### 5/5 — 非常好用，希望定制化选项增加

*2026-02-20*

希望增加自己设置时间单位等功能，比如“统计分析”中的“最近投入时间”每日每周时长（纵坐标）可以按小时/分钟/每8小时显示。目前每日只能按分钟，每周只能按小时

修复bug！！！！更新了ios26以后，记录时间以后下面的叉号和对号点不到了，必须往下划一点才能点到

### 5/5 — 周对不上

*2026-02-20, version 2.13*

感觉新年后的周和日对不上啊 是不是没更新日历🤣🤣🤣

### 5/5 — 时间统计添加年数据

*2025-12-03, version 2.13*

可否加入年度项目时间投入统计？谢谢

### 4/5 — 清晰簡單好用，專注進度學習必買

*2025-11-16, version 2.13*

如果能夠在一個大項目當中，再分細項，然後累計時間自動計算在大項目總時間中就更好了 1）.語文學習 -  累計時間：50h
1.1 生字 - 20h
1.2 句子 - 10h
1.3 語法 - 20h
1.4 應用 - 0h

等等…

### 3/5 — 計時聲音太吵了

*2025-11-03*

計時聲音太吵了，完全就是干擾，為什麼沒有設定可以關閉聲音呢？另外不付費只能記錄五個內容，有些雞肋

### 1/5 — 购买为何没有记录了

*2025-10-19*

我以前购买过 为何现在上线再上去不是高级会员了

### 5/5 — 希望可以有灵动岛功能

*2025-09-11*

以及桌面的实时活动 这样就很完美了

### 5/5 — 简约休闲式记录时间但统计分析有问题

*2025-08-29, version 2.13*

这款 app 是我已经使用了快四年的软件，符合我的所有需求。曾经有一个版本是最合适的，且还没有统计分析的 bug。要是开发者能修一下最近投入时间那个表格就好了：把分钟改为时间为单位，周表的y轴数值也不对。

### 5/5 — 今日专注

*2025-05-29, version 2.13*

希望能取消显示“今日专注”下降/提高百分比，只希望记录打卡，如果需要分析可以看“统计分析”。下降百分比有点打击记录积极性。

### 1/5 — 通知声音

*2025-03-10, version 2.13*

在手机休屏状态下，如果计时时间到，没有提示声音呢
