China’s extremely popular instant messaging app WeChat, which doubles as a Facebook-style social media platform, has taken over China’s mobile internet ecosystem.

A report released on Wednesday found that WeChat accounted for 29% of the time spent using mobile apps in China for May.  The report was put out by Mary Meeker, partner at Silicon Valley venture capital firm Kleiner Perkins Caufield & Byers, citing QuestMobile for the data.

WeChat’s parent company, Tencent, said that last month’s number of total active users on the app was up 23% year on year, CNBC reports. The 938 million active users puts the app in the same league with Facebook’s messenger app and WhatsApp, which both had more than 1 billion active users as of last month.
