Seems to be Kuaishou, similar but different to Douyin. Surprisingly it works and it doesn't look like I even need to log in to use it.

At a first glance the content is disappointingly similar to TikTok. Also, as I expected, with this type of content language is a non-issue.

Does anyone know if I can get the real Douyin? A search in the AppStore shows Kuaishou first and TikTok second.
