Thanks for using the application!
 
====================================

Objective-C is a reflective, object-oriented programming language that adds Smalltalk-style messaging to the C programming language. 

Today, it is used primarily on Apple's Mac OS X and iOS: two environments derived from the OpenStep standard, though not compliant with it. Objective-C is the primary language used for Apple's Cocoa API, and it was originally the main language on NeXT's NeXTSTEP operating system. Generic Objective-C programs that do not use these libraries can also be compiled for any system supported by gcc or Clang. 

Objective-C was created primarily by Brad Cox and Tom Love in the early 1980s at their company Stepstone. Both had been introduced to Smalltalk while at ITT Corporation's Programming Technology Center in 1981. The earliest work on Objective-C traces back to around that time. Cox was intrigued by problems of true reusability in software design and programming. He realized that a language like Smalltalk would be invaluable in building development environments for system developers at ITT. However, he and Tom Love also recognized that backward compatibility with C was critically important in ITT's telecom engineering milieu. Cox began writing a pre-processor for C to add some of the capabilities of Smalltalk. He soon had a working implementation of an object-oriented extension to the C language, which he called "OOPC" for Object-Oriented Pre-Compiler. Love was hired by Schlumberger Research in 1982 and had the opportunity to acquire the first commercial copy of Smalltalk-80, which further influenced the development of their brainchild. 

In order to demonstrate that real progress could be made, Cox showed that making interchangeable software components really needed only a few practical changes to existing tools. Specifically, they needed to support objects in a flexible manner, come supplied with a usable set of libraries, and allow for the code (and any resources needed by the code) to be bundled into a single cross-platform format. 

Love and Cox eventually formed a new venture, Productivity Products International (PPI), to commercialize their product, which coupled an Objective-C compiler with class libraries. In 1986, Cox published the main description of Objective-C in its original form in the book Object-Oriented Programming, An Evolutionary Approach. Although he was careful to point out that there is more to the problem of reusability than just the language, Objective-C often found itself compared feature for feature with other languages.

### 5/5 — Good

*2018-12-16, version 11.1*

I can code and this is the first time I can code on my phone!

### 1/5 — Unfortunately, yet another app where it is free to download

*2017-08-30, version 9.0*

But you cannot run any of your code without paying.

**Developer response:** Unfortunately, we can't offer free compilations.

### 1/5 — They're lucky there's no 0-star rating

*2017-03-19, version 9.0*

It's crap people..... you pay for "Hello World" to show up on screen. Use ads. • the end

**Developer response:** The sample "Hello, World" program is free to compile. To compile and run your own programs you have to buy compilation package.

### 1/5 — What is this crap?

*2016-04-25, version 9.0*

I have to pay to run a piece of code? Who would even do that? Just use ads instead if having people pay to run code.

### 4/5 — Its a great app.

*2016-04-06, version 7.6*

So disgusted by the 1 star reviews, These people couldn't code there way out of a wet napkin. This app is a huge undertaking for the Dev. The fact that it exists is awesome! Unlimited complies is worth way more than $2.99 if your complaining, ask yourself how much you just spent at McDonald's.

### 1/5 — In-App purchase

*2015-09-03, version 7.6*

This app would be better if it already had unlimited compilations or at least had more to begin with

**Developer response:** Just buy it and you will be able to use it as much as you want!

### 1/5 — Boo

*2015-03-02, version 7.1*

Not exactly what I was looking for I was hoping to get an app that would help me learn, use, and, practice object c.

**Developer response:** You need a compiler to practice. This app is compiler for your mobile device!

### 1/5 — Worthless

*2014-12-07, version 6.2*

Just a demo app, you need to buy to do anything. Horrible UI

**Developer response:** Why don't you want just buy it and use?

### 3/5 — Good but has flaws

*2014-11-18, version 6.2*

It does what I need it to do (let's me write code and runs it) but there are some other features that come with this app that don't work at all really.  It shouldn't cost $3, it should be $2 but whatever.

### 4/5 — Great for learning

*2014-10-04*

This is what I needed for taking my first step towards learning programming. Writing programs is the only way to learn, and away from my iMac this allowed me to learn from my mistakes.
Only not giving a 5 because sometimes a run fails, and without changing anything it will work the 2nd time.
