MobiRuby takes advantage of mruby, which is a minimalistic implementation of Ruby. It is a relatively new endeavour by the Ruby founder, matz. Watch the keynote. mruby was released on April, 20th, 2012.
MobiRuby aims to replace Objective-C/C/Java on mobile platforms with Ruby, just like you can use Lua or Mono to build apps on those platforms. Now, we have mruby thanks to Matz!
Now, we are working on iOS and Objective-C. We will port MobiRuby to Android at next step.
Currently, You need call Cocoa functions throught Ruby code for making MobiRuby app. We're focusing to build Cocoa bridge now.
In next step, We'll create natual Ruby library for making iOS application.

AppStore already accepted MobiRuby based apps.
