Here's a stat I heard a few years back: WeChat has over 50% time share in China. Meaning people in China are on WeChat more than all other apps on their phones combined.
That seems high to me. A lot of people seem to spend most of their time on xiaohongshu (like Pinterest?), douyin (tiktok), bilibili (like YouTube) etc. WeChat is good for its utility functions like ordering a Didi, chatting with friends or ordering from a restaurant but for entertainment (where people spend most of their time) it's pretty basic.
