Messaging and social apps led the way to a triple-digit jump in app use by smartphones last year
Utilities and productivity apps had the next largest increase in use at 149%. Those two categories were followed by Music, Media and Entertainment (78%), Lifestyle and Shopping (77%), Games (68%), Sports Health and Fitness (49%) and News and Magazines (31%).
Snapchat had a fantastic 2013. The messaging app offers video, photo and text messages that disappear after 10 seconds. In June, the company completed a $60 million round of financing at a valuation of $800 million and by the end of the year Snapchat was turning down offers of $3 billion and $4 billion from Facebook and Google respectively. But as the calendar turned to 2014, 4.6 million Snapchat subscribers had their phone numbers and usernames partially leaked as a way to show up the company for not closing exploits pointed out by a security company. Snapchat has since announced that it will update the app to make it more secure.
