We are looking to make an app that retrieves data (in JSON/RSS; whatever the programmer would like) from our server and shows it in an app. Structure;

- all data has a category and a type (there are 3 types)
- icons in the bottom are to select the types
- a list of categories are to drill into categories
- after selection it shows a list and you can click into details
- when you are offline it should show the previously loaded information (not an error)

We would like something crossplatform (Titanium Appcelerator for instance), although the first version will be only iphone/ipad.

Please quote.
