The Facebook Groups app has a more familiar design than those of previous Creative Labs apps like Paper and Slingshot. It does, however, follow those apps in using a pull-down gesture to refresh group activity and to take you back to the home page when you’re inside a group. Circular buttons for each of the Facebook Groups I’d already subscribed to appeared, each showing the number of unread posts.
Four icons along the bottom switch you between Groups view, Notifications, Discover, and Settings. The Notifications page is similar to what you get when you tap the globe icon in the Facebook app click here.
