In English, it seems to be called rednote. But I doubt that it will be a real successor. At the moment it's a funny meme, and for some people satisfied cultural curiosity. But we already see the problems appearing, from the poorly localized interface, to people getting banned for reasons outside their understanding.

My guess is, at the end we will see maybe some million users from the USA and some more millions from around the world moving to this app, and maybe bringing a new interaction between the countries, but the majority will end up somewhere else.
