Facebook Pages Manager is standalone app from Facebook. This app allows you to control your Facebook page without being directly connected to you personal Facebook account.
Clean and clear
It is simple to use. The main wall shows the same information it does on the original app, but Facebook Pages Manager also includes the option to view Insights and statistics about your posts. You can updates the page's status, add photos, and filter posts not normally seen through the webapp and standard Facebook app
Perfect for some
Using the same user interface as the Facebook app, Facebook Pages Manager is great for users who have their own page or multiple pages they manage. For normal users, Facebook Pages Manager is an unnecessary app.
Facebook Pages Manager is another specific-use app from Facebook.
