You might think people use their smartphones and tablets most when they’re out of the house: in the morning on their commute, or during the day at work. Probably not in the evening, when they’re at home with their TVs and computers.

This is exactly wrong. The chart above, first reported by PandoDaily and built from data collected by Localytics, an analytics company that focuses on app usage, shows that, in the US, people use their mobile devices the most at 9 p.m.

What does this mean for app developers and content creators? Depends on what you make. Videos, games, and social media apps are popular to use in the evenings, while news apps see their biggest spike around 7 a.m.

The general pattern of evening peaks also holds in other countries, though the profile throughout the day looks slightly different.
