### 5/5 — This is great.

*2016-08-03*

This is a beautiful app that supports many different syntax themes. It doesn't have editing support in the free version, but it doesn't need to. When I need to learn a new codebase, sitting down with this app and going over the project copied from a computer is extremely convenient.

### 1/5 — Do Not Buy This

*2016-05-12*

Even if this app were free, I would still say don't download it. This app does not allow you to send files to it from the Dropbox app, which is essential. I hope I can get a refund.

**Developer response:** 2.0.0 version support dropbox, please upgrade it

### 1/5 — Not an editor !!!!!

*2016-05-01*

Highly ambiguous description. This is not an editor but merely a desplay of existing codes (that you have to go and fetch on internet). Disappointing !!!

**Developer response:** Please update to version 2.0.0. Thank you for your support.

### 5/5 — 改进建议

*2015-12-02*

1、希望支持行号和代码自动换行功能
2、希望增加方法和属性快速导航
3、减少崩溃

最后赞一下这个App 读代码很舒服。

**Developer response:** 已经支持，请更新至2.0.0版本，进行了全新的改版

### 1/5 — 坑人

*2015-11-24*

坑人，花钱买了还是打不开10k以上的，还频繁崩溃…勿买！！！

**Developer response:** 如果你曾经购买过，强烈推荐你更新至2.0.0版，并通过restore purchase还原购买，绝对超值

### 4/5 — 希望把此app添加打开方式

*2015-06-08*

比如我在某网盘下载了一个cpp文件，现在我想用codemate打开这个cpp文件。但是这个文件的打开方式中没有codemate。希望添加！

**Developer response:** 目前这个已经支持了，请更新2.0.0版本。

### 5/5 — Works great with A TUTORIAL!!!

*2015-06-07*

No tutorial, but forget that! I could Google search anyway for one! This app works great, absolutely no bugs. However if necessary please program an offline tutorial and make the editor easier to use. Thanks.

### 2/5 — 程序崩溃频繁

*2015-06-04*

看看简单的小文件可以的，但是程序太容易崩溃了，作者修复一下吧。

**Developer response:** 已经修复了，请更新全新改版和重写的2.0.0版本

### 3/5 — pad Air中闪退

*2015-05-24*

如题

**Developer response:** 请更新2.0.0版本，有惊喜

### 1/5 — ??? what the hell is this !!!

*2015-04-11*

... the app does not work !!!

**Developer response:** please update 2.0.0 version from appstore
