Friendcaster for Facebook
Facebook has yet to release an Android app that's truly optimized for tablets, but that doesn't mean you have to suffer. Just download Friendcaster for Facebook, the free third-party Facebook app that does make tablets a priority. Friendcaster, now for phones and tablets both, lets you keep up with your News Feed and post status updates from an intuitive, tablet-oriented interface. The app provides full support for Facebook photos and messages, as well as for groups, events, and pages (Facebook chat is not integrated directly into the app, but is available via a free add-on). Friendcaster has optional notifications, too, if you like to get alerts when new activity happens. An ad-free version costs $5.
