In case there was any doubt that messaging apps were the future of communication in the mobile-first era, a new study released this morning puts some solid numbers behind their traction – and their increasing dominance over email, among today’s youngest users. According to a report from App Annie, email is effectively dying among this crowd. Those aged 13 to 24 now spend more than 3.5 times overall usage time in messaging apps than those over 45 years old, while the older users still default to apps that replicate desktop functions, like email and web browsers.The data for these findings comes from a large sample of real-world users, notes App Annie, combined with the company’s own proprietary data sets. However, it only focuses on Android smartphone users, which in the U.S., doesn’t present a holistic overview of the market. Adding iOS data could change these numbers somewhat, though it’s likely that the larger trends would remain.For those who did not grow up with a smartphone in hand, there’s a propensity to use the device like a smaller personal computer, it seems. Those aged 45 or older spent a higher share of their time in the top 5 mobile web browsers on their phone than any other age group, for example. Plus, they spent more time in the top 5 email apps for Android and less time in the top 5 messaging apps.
