This message has been posted on their discord server yesterday, currently the app is being worked on and has no definitive ETA. We probably have to use other forks until that. I don’t know whether I can share the discord server’s link so not sharing that until a mod gives heads up.
But is there a way to have it on iOS? Maybe a web app like wefwef/Voyager?
