These days, smartphone users have millions of apps to choose from. But how many apps do they actually use? According to a recent Nielsen report, the answer is: a little more than two dozens.

In the fourth quarter of 2015, iPhone and Android smartphone users in the U.S. used an average of 27.1 apps per month, spending more than 40 hours with them. Interestingly, the amount of time people spend with apps continues to increase, whereas the number of apps they use pretty much stopped growing three years ago.

Apparently, there's a limit to how many apps people actually use, regardless of how many apps are available and how much time they spend using them. To put it differently: there's an app for every need, but there's no need for every app.
