## What is Kotlin Programming Compiler?

Write Kotlin code directly on your iPhone, iPad and iPod Touch! This app is ideal for learning and testing code snippets!

Kotlin is a cross-platform, statically typed, general-purpose programming language with type inference. Kotlin is designed to interoperate fully with Java, and the JVM version of its standard library depends on the Java Class Library, but type inference allows its syntax to be more concise. Kotlin mainly targets the JVM, but also compiles to JavaScript or native code (via LLVM). Kotlin is sponsored by JetBrains and Google through the Kotlin Foundation.

Features:
- Compile and run your program
- View program output or detailed error 
- Custom keyboard for easy input of frequently used characters
- Optimized for connecting with external physical/bluetooth keyboard
- Advanced source code editor with syntax highlighting, bracket completion and line numbers
- Open, save, import and share Kotlin files.

Limitations:
- Internet connection is required for compilation
- Maximum program running time is 20s
- One file can be run at a time
- Some file system, network and graphics functions may be limited
- This is a batch compiler; interactive programs are not supported. For example, if your program provides an input prompt, enter the input in the Input tab prior to compilation.

### 3/5 — Nice but must be improve

*2020-10-02, version 1.7.1*

Please release a new update about “code insight” option. It is too boring to writing all code blocks each time.

### 5/5 — Nice

This app is wonderful! thanks to developers of this app

### 5/5 — please make a jdk

*2020-03-15*

nice compiler! please make a jdk thanks 🤗

### 5/5 — As advertised

*2020-03-13*

Does exactly what I need. This compiles Kotlin scripts on a web compiler so only static input is allowed. Perfect for using your phone as a mobile kotlin learning center :) Thanks dev!

### 1/5 — Works, but ads are impossible to exit

*2020-03-12*

I do not have a problem with ads on free software, but on an iPad the full screen ad has no option to exit. That’s really not nice
