As the threat of a TikTok ban looms, some U.S. TikTok users are flocking to Chinese social media app Xiaohongshu – making it the top downloaded app in the U.S.

Chinese social apps Xiaohongshu and Lemon8 have soared to the top two spots on Apple's iPhone charts ahead of the U.S.'s impending TikTok ban.

Ahead of a potential ban this Sunday, Xiaohongshu, which is also known as Red Note or Booktok, quickly became the most downloaded free app on the U.S. App Store on Tuesday, surpassing Lemon8, a social network app that is also owned by TikTok parent ByteDance.
