Facebook, the most-famous social network also has its own official app for iPhone.
When you run this application, you enter that virtual world where you share your thoughts, pictures and videos with your friends. Now you can access it easily from your iPhone, iPod Touch or iPad.
It works in a pretty similar way to the original Facebook on the computer. This time you'll have all sharing possibilities on your hands.
Touch the screen to type what you are doing, say where you are or upload any photo. Of course you can access your friends' profiles and gossip a bit.
From now on, you'll be always on. Oh! It's totally free.
Requires iOS 7.0 or later. Compatible with iPhone, iPad, and iPod touch.
