### 4/5 — 功能完整不错，适配下iPad 多窗口

*2025-03-30*

有更多iOS技术升级下

### 4/5 — 算法部分能不能加多个筛选项，比如100或者top200

*2024-05-19*

算法部分希望加入个性化筛选，100或者top200并且支持写自己的note

### 4/5 — I don’t think we have a lot

*2023-06-23*

For the day I’m not going anywhere

### 4/5 — Wine nice to have JavaScript

*2022-02-13*

It’s an amazing app, however I’m a front-end developer and I usually work with JavaScript, it would be nice if this app had some examples with JavaScript.

### 4/5 — Suggestions for changing explanations

*2021-02-27*

It would be great if I could suggest / give you edits for typos, I.e like a wiki! 

This app is lovely; I’m sure the explanations can be improved if users have input.

### 4/5 — Thanks for rethinking

*2020-05-28*

Previous update was disgusting and I was about to uninstall. Latest update on integrating leet code problems is bit relieving. Thanks for this. I’ll suggest you to add settings option with restore purchase based on user level. Such that I can login with all devices.

### 4/5 — 排版有点糟糕

*2019-12-08, version 1.2.7*

刚开始我也觉得这个app很好然后买了pro版本，但是呢，因为最近开始刷题发现提供的部分代码排版太糟糕了，需要自己手动排版才能看。

### 4/5 — 改进与优化

*2019-11-03*

1、标签页，右上角菜单连续点击后页面卡死
2、笔记编辑、保存后去除了每行空格缩进
3、题目所贴标签与实际行动解法部分不一致。标签页，比如题目为动态规划标签、但实际题目用不上动态规划解法。希望优化题目解法与标签对应关系

**Developer response:** 谢谢反馈，将在未来改进

### 4/5 — 建议增加搜索功能

*2019-07-21*

能直接通过关键词搜到某个题

### 4/5 — 建议做个账号系统

*2019-07-21*

保存笔记在账号里，在其他设备终端登陆时能够同步记录

**Developer response:** 谢谢反馈，现在笔记是通过iCloud同步的，app功能比较简单，所以一直没考虑过增加账号系统

### 4/5 — 查看笔记代码格式错乱

*2019-07-12*

上次说的笔记不支持滚屏反馈目前已经修改，点个赞，但是目前又有一个新的问题哈。
在笔记当中编写的代码格式无问题，保存笔记查看的话每行的占位符会被自动清空，导致格式错乱，但是回到编辑页面再次查看格式却是好的，希望查看笔记页的空格不被清除，另外是否可以新增一个Tab按钮方便编码

**Developer response:** 谢谢反馈，将在下个版本修复

### 4/5 — 升级为会员问题

*2019-06-28*

下周该团结之后，发现没有登陆功能。现在已经升级为会员了，如果我换一个手机下载还是会员吗？这个软件是靠什么条件来判断用户以为会员的呢？

**Developer response:** APP功能比较简单，没有账户体系；换设备恢复购买pro即可（不会重复扣费），你的购买记录保存在Apple内购服务器上的，一次购买永久使用

### 3/5 — 还不错，有部分不足

*2019-06-11*

结果只显示官网里面最热的解决方案。其实官网里面排名靠前的几个解决方案都很优秀，有时候排名第二第三的很多算法更优秀，只是解题方案少了。另外，很多优秀的方案都会提供解决思路，我觉得那个比代码更为重要，方便理解，希望开发者考虑一下怎么去优化一下

**Developer response:** 谢谢反馈，之后将会做相关改进
