The Rapid Prototyping Toolkit for Mobile Apps

I am working on a set of tools to help mobile developers to quickly prototype apps. The platform will consist of an online dashboard for editing and publishing prototypes, a mobile app for running the prototypes and an emulator for testing prototypes before publishing. The mobile app will initially be available for android only. The platform will communicate with 3rd party apps via a HTTP REST, with JSON formatted data. Developers will be able to develop their prototypes in their language of choice provided they host behind an HTTP server.
