Users can selecting any item by touching it. Three icons along the bottom will let you view your profile, see your gradebook, and access your message center.
Choosing a class will show you a schedule of activities. the menu at the top allows you to switch to a list of class discussions, a class roster, and a file manager. You can also grade items for that class with the optional Speedgrader for iPad app. Both apps are available in the app store.
An Android app should be available soon.
