This is an unofficial clone of the Moodle Mobile app for iPhone that works on Android and Blackberry devices.
It should work also on iPhone and iPad.

This application is intended and has been designed to be easily customizable by Institutions (University, corp..). This application uses common web technologies (HTML5 + CSS3 + JavaScript) and the high level multiplatform mobile Javascript framework Phonegap.
Phonegap enables you to build your app once with web-standards and deploy to multiple platforms.

Please note that this app is not a replacement or improvement of the official app for iPhone (and Android when available). It has beend designed to be easily customizable and extendable using web technologies by anyone
