### 5/5 — Scam

*2026-02-12, version 2.7*

This app is my budget. It’s a scam.

### 5/5 — Some novel features

*2025-06-14, version 2.3*

I’ve used the authors’ other compilers for some time. The authors respond to queries quickly. This compiler has similar interesting features to their other ones and also their quirks. I like it because it’s quick and easy to try out small programs.

### 1/5 — 不好用

*2025-02-26*

编译器经常出现bug

**Developer response:** 欢迎反馈任何bug :微信或QQ:1301367159

不要因为18元钱，而错过了一款好软件，开发不易，望君珍惜。

### 5/5 — 为了感谢作者所以购买

*2018-01-05*

迄今为止苹果手机上最好用的C语言编译器。

### 4/5 — Nice little application

*2017-06-29*

Enjoyed learning c coding, the tutorials and reference guide is well written.

### 3/5 — It can be better

*2017-05-03, version 1.5*

I'm a student at UT Tyler. I'm just learning C programming. All my programs, as of now, are pretty much simple programs. This app can do simple ok.

But, I can't return two values in a function and it doesn't handle strings well.

If this can do like Visual Studio, it will be awesome!

### 5/5 — 很好

*2017-03-18*

不错。很适合我这样的初学者

### 5/5 — Fantastic
