RubyMotion allows developing iOS applications using the Ruby programming language. The document discusses RubyMotion, including writing iOS applications in Ruby, using the power of Ruby in apps through metaprogramming, running applications using the Rake build tool, interacting with the running app through a REPL console, using libraries like CocoaPods, BubbleWrap and Sugarcube to access device capabilities and utilities, and resources for learning more like books and community events. Real-world apps built with RubyMotion are also mentioned.
