SimilarWeb examined the amount of time Android users in nine countries spent on social apps Facebook, Instagram, Twitter and Snapchat during the first three months of 2016 and found that there has been a year-over-year decline. Facebook-owned Instagram saw the most significant drop of 23.7 percent (36.2 percent in the U.S.), followed by Twitter and Snapchat. Facebook was down 8 percent overall, 6.7 percent in the U.S. However, Facebook users in the U.S. spend a daily average of more than 45 minutes with the app. “Meanwhile, Facebook’s messaging apps — WhatsApp and Messenger — increased installs, up 15 percent and two percent respectively,” notes CNBC.
