Facebook this year continued to hold the number one position as the top app installed on U.S. smartphones based on the average number of unique users.
Facebook led the way with more than 126 million average unique users each month, up 8 percent over last year where it was also the top app.
For what it’s worth, Facebook itself said last month that it had 1.39 billion mobile monthly users worldwide, up 23 percent year-over-year, and 217 million monthly actives (not just mobile users) in the U.S. in Canada in Q3 2015.
Meanwhile, in terms of the battle between operating systems, the U.S. still slightly favors Android with a 52.6 percent market share compared with 42.7 percent for iOS. Barely 3 percent of smartphone users owned a Windows Phone device in the past year, followed by BlackBerry which somehow still managed to claim a 0.7 percent share of the market.
