I recently posted a case study on our competition entry FringeFest.ca, for the Apps4Edmonton competition that made use of Drupal, Appcelerator Titanium and Mobile Webkit to create a web app, iphone app and smartphone friendly version of the web app using Open Data made available by the City of Edmonton.
Key modules include: Services, Feeds, JSON Server, Views, Location and more detailed in the case study
The Edmonton Fringe Festival is North Americas largest & longest running theatre festival with over 160 productions, 1,200 performances and 39 venues this year. This app aims to make sure that you dont miss out on anything by helping you to plan your festival, write and read reviews on what shows are popular and access useful maps and information.
