This is an extremely trivial test app written using RubyMotion. It fetches all of the public Gristmill GitHub repositories and lists them in a table view. When you tap/click on a repository it displays an alert with the number of watchers.
You must have a registered copy of RubyMotion installed in order to compile and run this application.
git clone git@github.com:gristmill/watchers.git
cd watchers
bundle
rake
