Facebook Pages Manager
For Page admins, this app is handy to have. It allows you to perform all the basic functions of managing your fan page like viewing Insights, posting new content and checking new Page Likes and Notifications.
If you’re already familiar with using Facebook’s personal profile app, you’ll have no problem learning how to use Facebook’s Pages Manager app. For the most part, the functions are the same, just tailored for managing a fan Page instead of a profile.
With the Facebook Camera app you can share photos to Facebook quickly and easily, as well as view a feed of your friends’ photos. What the itunes app description fails to mention however, is that this app also gives you several photo filters to choose from (similar to Instagram).
