Thanks to the Open Stream API, Babbler behaves just like any other application from the Facebook Application Directory and needs to be authorized before it can act on a user's behalf. This ensures that the account data and privacy are secure and that the application cannot be used for spamming.

Just like in the full Facebook site, the default screen that Babbler shows on launch is the Feed, which enables users to post, read, „like” and comment on updates and Wall posts. It also provides quick access to friends' profiles , albums, events and tagged photos. The „Friends” section shows all users' connections, additionally providing information on whether his/her friends are online at the moment.

Perhaps the most important feature for people who like to update their profiles on the go is the photo and video upload capability that works in the background and integrates with the phone's Gallery application. Additionally, users can share links from the Browser or Youtube app and follow links that others have posted in the Feed.
