ProMotion-iap is in-app purchase notification support for the popular RubyMotion gem ProMotion. It also works as a stand-alone gem if you are not using ProMotion. ProMotion-iap 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 it, 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.
