Facebook’s new Home Android launcher has passed the 500,000 download mark on the Google Play store after a little over a week in the wild, though it continues to accumulate mostly negative reviews and has sunk to an average rating of 2.2. The milestone was noted by Benedict Evans on Twitter. Facebook first released the software in the US on April 12 before rolling it out to international users on the 16th. 500,000 downloads is a modest start for Facebook, which has a global user base of over a billion, but the app’s audience is limited since only a few Android devices are supported at this time. By comparison, the main Facebook app on Android has between 100 million and 500 million downloads. As another point of reference, Instagram brought in 1 million downloads in just 24 hours when it arrived on Android last April.
