Wayup, a startup that connects college students with local job opportunities, queried 1,000 US college students about their favourite  apps and found that Facebook Messenger, Snapchat, free digital wallet Venmo were the top three apps on decline, VentureBeat reported.

The survey was sent out five times throughout 2015 in an effort to suss out larger mobile app trends. The study found that Facebook Messenger, Snapchat, and Venmo were mentioned less and less over the course of a year.

However, the list is a little deceiving. For instance, banking apps en masse saw a decline from September through December of 2015. "Venmo is  the clear favourite among payment apps, cited five times more frequently than the next most listed app, PayPal," the study noted.
