### 5/5 — 基本功能完好，有一些建议。

*2017-12-20*

因为iOS对目录的限定，模版文件或者说明文档中应该添加关于文件写入的提示，比如：那些目录是可以供用户写入的。
Ruby的一些常用模块并没有，比如JSON，Net模块。
因为iOS作为移动端毕竟不能作为主力执行机器，如果能支持网络模块可以大大扩展软件的可用性。而Python版本有ftplib和httplib，_(:з」∠)_。
代码编辑器能支持emacs模式的话当然就更好了，😄，当然这感觉相当麻烦。

另外，也不知道能不能把自己编译的iOS版本Ruby C扩展丢到目录里边直接require，求说明！lol

### 5/5 — Great

*2017-06-07*

Wow

### 1/5 — why did I  pay for this?

*2017-04-05*

this app is stupid. was looking for a way to write and run ruby code... this is not it. would give zero stars but app store won't let me. do not buy.

### 5/5 — It's a cool app for learning a writing ruby!

*2017-03-05*

I love how it has syntax highlight and autocomplete! And even a cool little tutorial with chapters to get you started! I gave it five stars but I'm also not all that stuck up about things it's a great app over all!

### 1/5 — poor english localization, horrible interface

*2016-11-14*

This doesn't do what it promises, at least as far as I can tell. There is no way to actually run any of the code you write in the editor, despite the name of the app indicating that's possible. Te interface is a total mess--ill conceived even in its native language, and made much worse by very poor english localization. Includes garbage like a toggle for the phone flashlight and a calculator. A half-baked project and not worth a purchase.

### 5/5 — Ruby 2.0 Has Features

*2016-09-21*

Try it.  You'll like it.

### 5/5 — Great for coding on the go

*2015-12-25*

The keyboard has an interesting feature.  You can type all the extra characters for coding really easily!  Haven't seen this before.  Makes coding on the iPhone really easy.

### 5/5 — Good to Great

*2015-05-23*

Does what it says. Easy to figure out most everything and easy to test code for work. A+

### 2/5 — Still no easy way to type underline

*2015-03-23*

Ability to type underlines is critical for Ruby. 

The shortcut system in the editor is great but it provides shortcuts for unimportant symbols like ; and ~ in preference to something you might use multiple times per line i.e. underline _ _ _ _ which takes three key presses to type right now. I need a single key shortcut for ~ like a fish needs a bicycle. The shortcuts are for better for perl maybe?

The ridiculous self promoting points for spam posts / built in astroturfing is still sickening and has no place in a paid app.

This loses two stars for weak underline support and another for the disgusting AstroTurf spam prizes as far as I'm concerned.

There's no graphics library and no gem support - things I would definitely pay more for. As is the limited library support makes this a bit of a token effort.

### 5/5 — Great

*2014-11-09*

Verygood
