ProMotion was created by Infinite Red, a web and mobile development company based in Portland, OR and San Francisco, CA. While you're welcome to use ProMotion, please note that we rely on the community to maintain it. We are happy to merge pull requests and release new versions but are no longer driving primary development. ProMotion is a RubyMotion gem that makes iOS development more like Ruby and less like Objective-C. It introduces a clean, Ruby-style syntax for building screens that is easy to learn and remember and abstracts a ton of boilerplate UIViewController, UINavigationController, and other iOS code into a simple, Ruby-like DSL.
