Mashable shared this great chart from Statista and GlobalWebIndex that shows the top 10 most-used smartphone apps in the world:

top smartphone apps

What's interesting is that 9 out of the top 10 apps are social media-related, with 7 of them dedicated to social communication.

Intriguingly, WeChat / Weixin is already in the top 5 apps globally, putting it in the top 3 mobile social networks in the world.

Yet another reason why brands shouldn't separate their strategic approach to mobile and social.
