I wasn't sure what RubyMotion was. If you are also wondering, here's what Wikipedia [1] has to say:<p>> <i>RubyMotion is an IDE of the Ruby programming language that runs on iOS, OS X and Android. RubyMotion is an open-sourced commercial product created by Laurent Sansonetti for HipByte and is based on MacRuby for OS X. RubyMotion adapted and extended MacRuby to work on platforms beyond OS X.</i><p>> <i>RubyMotion apps execute in an iOS simulator alongside a read-eval-print loop (REPL) for interactive inspection and modification. 3rd-party Objective-C libraries can be included in a RubyMotion project, either manually or by using a package manager such as CocoaPods. Programs are statically compiled into machine code by use of Rake as its build and execution tool.</i><p>[1] <a href="https://en.wikipedia.org/wiki/RubyMotion" rel="nofollow">https://en.wikipedia.org/wiki/RubyMotion</a>
