The new Facebook Home app launched today, but it’s currently only for Android smartphones. A version for tablets is in development, however.
In the mean time, those who have an Android phone can download the app on the Google Play Store.
More About Facebook Home
Rather than being just an app, Facebook’s new software changes the emphasis of a user’s phone to social networking. As the most obvious examples, the lockscreen and the home screen are replaced with images and posts from the user’s Facebook feed.
Other applications can still be launched, but only from within Facebook Home.
