Comparing the app usage of the graduating class of 2015 to last year’s grads shows some apps are cooling down, while others have only gotten hotter. A survey found that Snapchat has experienced one of the biggest usage gains, at a 32% increase. But that’s nothing compared to Spotify, which this year’s teens say they are using 78% more than last years’. Meanwhile, Pandora use dropped 11%, perhaps showing the increased streaming competition is impacting them. (Daily Dot)
