In a recent survey, ComScore asked app users ages 18-34 about the apps they "can't go without." The top 10 includes the likes of YouTube, Gmail, Instagram, WhatsApp, Google Maps, and Facebook. Participants in the survey were asked to pick their top 3 most essential apps. Andrew Lipsman, the senior vice president of insights and marketing at comScore, told Business Insider that the list "speaks to a broader insight, which is that millennials seem to recognize the importance of the more functional apps, like Amazon, Gmail and Google Maps."
