Write iOS, Android and OS X apps in Ruby

RubyMotion is a revolutionary toolchain that lets you quickly develop and test full-fledged native apps for iPhone, iPad, Mac and Android (beta), all using your favorite editor and the awesome Ruby language you know and love.

Why RubyMotion? Let's get started!

RubyMotion apps are created and later maintained from the terminal command-line. A RubyMotion project is based on the Rake tool and can be configured by editing its Rakefile.


RubyMotion apps are fully native. You have access to the entire set of public iOS, Android and OS X APIs and can use 3rd-party Objective-C and Java libraries. You keep your favorite text editor.


Run your app in the iOS and Android simulator. An interactive shell is available for introspection, live coding and debugging. Cover your app with functional and integration specs.


Run your app on your iOS and Android device. Generate .ipa, .apk and .pkg archives for Ad-Hoc distribution. Prepare a submission for the App Store and Google Play.

Why RubyMotion?

Real native apps

RubyMotion implements the Ruby language on top of the core technologies that power iOS, Android and OS X.

RubyMotion apps are also statically compiled into optimized machine code using an ahead-of-time compiler. Code is never interpreted.

Cross-platform support

RubyMotion lets you write iOS, Android (beta) and OS X apps using the same language and development environment.

You get to call into the entire set of native APIs for each platform from Ruby, and keep using your favorite editor.

Use Ruby, be happy

Ruby was designed to make humans productive and happy.

RubyMotion keeps the Ruby way, by providing you with a command-line interface, an interactive console, letting you use the editor of your choice, a powerful testing framework, and gems.

What are you waiting for?

RubyMotion is already used by thousands of companies and individual developers. You will be in good hands.

RubyMotion offers developers the expressiveness of Ruby with no compromises. It's hard to imagine a more appealing way to build native iOS applications.

Building on Apple’s platform has traditionally required experience in a niche programming language, Objective-C. With the release of RubyMotion, anyone can make a completely native iOS app using the power of Ruby.

I’m convinced that I wouldn’t have been able to ship an iPhone app at all without RubyMotion.
