Facebook’s major push into the mobile world puts the social network at the heart of Android smartphones, which should appeal to its most-addicted users. Friend updates appear on the lockscreen, from which users can double-tap to like a post or chime in with a comment. And Facebook’s messenger program can move with you from app to app with an overlay that keeps you from having to switch into its own app.

Still, while the app makes using Facebook much easier, it probably won’t appeal to those who aren’t heavy Facebookers. It takes a few more swipes to get to your apps, and letting Facebook become the center of your phone means that Android users lose a lot of customization. There’s also privacy to consider: By default, Facebook does not require a password to comment or like items, meaning users will have to change those settings on their own if they’re uncomfortable with that.

Android users should also know that Facebook Home is available only on a handful of phones: the Samsung Galaxy S III and Galaxy Note 2 and HTC’s First, One, One X and HTC One X+. Free, for select Android phones.
