### 4/5 — One off payment

*2024-04-06*

Hi is this a one off payment ?

### 5/5 — 一直在用，非常好👍

*2024-01-24*

Free版其实够用了，但是付费的，功能更多。界面很简洁，又可以自定义，适合强迫症。字体大小均可调整。

学习的时候，打开手机或者平板计时，又有仪式感又能专注。

希望永远不要下架！

### 4/5 — Records

*2023-06-19*

How can you delete the records?? And if possible, can you put am/pm indicator for 12 hr format?

### 4/5 — 番茄钟进入后台就不会提示怎么办？

*2023-03-13*

使用还算方便 但是番茄钟进入后台或者屏幕关闭就不会提示时间到了 可以后面改进这点吗

### 5/5 — 非常好的软件！提一个小建议期待可以加上😄

*2022-12-10*

希望能加一个⏰的界面，有时候数字看多了就有点审美疲劳想看⏰转动带来的时间流逝更有触动

### 5/5 — 真的很不错

*2022-11-03*

以前也用过类似的软件 但很多功能都需要会员 就劝退了
这个真的很棒 设计的恰到好处 方便简洁希望往后继续改善越做越好

### 4/5 — Has large widget

*2021-11-19*

Would like to get rid of flip style on widget and use what is selected in app.  But great to have larger clock widget.  Would also like color picker, but that is so trivial it’s hardly worth mentioning. 
So very glad to have larger clock on my Home Screen.

### 4/5 — 中上评

*2021-10-19*

风格确实很简洁，但是我希望能够同时显示日期和自定义的日期。这是我花钱之后发现不能同时满足这两点之后，有些些微后悔的地方。

### 4/5 — 改进建议

*2020-12-18*

希望把倒计时的那个自定义日期的项目字体可以调大一点。比如“距离高考”…还有多少天，希望可以大一点

### 5/5 — 倒计时翻页效果能不能去掉黑色框框

*2020-12-15*

倒计时或者番茄钟的时候翻页效果能不能变成纯色数字，可选择纯色数字啊，沉浸模式有点突兀
