This may sound impressive, but Facebook has over 1 billion registered users, and their main Android app has between 100 and 500 million downloads, and their Instagram app hits 1 million downloads in 24 hours when it launched on Android last year.
It looks like Facebook may have some work to do to make Facebook Home as popular as their other apps, it hasn’t had the best reviews so far on Google Play with around 52 percent of the reviews being one star.
Facebook Home received an unusually large number of one-star reviews shortly after launch, and that trend has continued. At the time of publishing, 5,617 of the total 10,905 reviews (52%) were one-star ratings.
Google Play doesn’t provide exact data on individual app installations, but a Google cache of the Facebook Home listing from April 19 shows the number of installs at 100,000 to 500,000. Currently, the app is listed in the 500,000 to 1 million range.
