Chinese social media app RedNote, known in China as Xiaohongshu, gained nearly 3 million U.S. users in one day earlier this week as a flood of self-proclaimed "TikTok Refugees" joined, according to new data from analytics firm Similarweb.

TikTok is still three days away from a likely ban in the United States, but many users are already bidding the app farewell and seeking out alternatives.

As a TikTok ban looms, Americans are starting to download RedNote. Here's what you need to know about the app.

With the TikTok ban in the United States less than a week away, Xiaohongshu has surged to the top of Apple's iOS App Store downloads.

The ban results from an April law signed by President Joe Biden and is the first time the United States has attempted to shut down access to an app with such a large user base - roughly 170 million domestic users.
