There is existing all around the web some tools which are based on html5 which helps you to create basic mobile applications for most of the existing mobile platforms: Android, iOS, Blackberry and Windows Phone.
This tools are mostly WYSIWYG editor based.
This providers creates for you an app based on simple html templates that run smoothly on all this platforms, then they just create for you a container that you can submit to the stores.
The goal of my project is to create an independent, open-source & more flexible platform to create this kind of small applications where you don't need to stick to one provider and can host the applications yourself. Little bit like ownCloud but for your mobile apps.
