When it comes to screen real estate on Android devices, Facebook and its family of apps rule the roost. As seen in this chart from Statista, Facebook is far ahead of the competition in Android app downloads. The top 4 most downloaded apps are all owned by Facebook. Combined, these Facebook apps racked up 297 million downloads last month.
According to Priori Data, WhatsApp is the breakaway star of the group with 103.64 million downloads. Facebook acquired the messaging service in February of 2014 for $US19 billion. The app has grown even bigger since the acquisition. In a blog post from July 26, WhatsApp said that it had 1 billion daily active users sending 55 billion messages every day.
