It would be no wrong if we say fBook as an updated version of the mobile Facebook website rather than calling it as an app. It has all the capabilities that a mobile version of the web site has along with two additional tools. The first tool is to upload a photo and the other is the settings button, using which you can choose for the Notifications to pop up or vibrate your phone when you have some notifications. You can also choose to set the Facebook to remind you every 5 min up to 1 hour.
This app is definitely not a stand alone app but includes the two most important features that we wished the mobile version web page had included. The app is worth giving a try.
