GameRoom is a very simple Rails app to showcase Stacker, an iOS view-controller to make building hybrid native/web iOS apps much simpler.
Here's what it looks like running inside Stacker:
Make sure your machine has Ruby 2 and Rails 4.
$ git clone https://github.com/lokimeyburg/GameRoom.git
$ cd GameRoom
$ bundle install
$ rails s
Now check http://localhost:3000
and you should see GameRoom running in your browser.
