It was really easy for me actually, just go to wefwef.app (or whatever the new url is now that it’s called voyager) on my browser of choice, go to settings and tap install, and then it automatically makes an icon on my home screen to put where I want. Still gotta sign in or make an account but that’s fairly easy, but works and looks like a normal app for the most part otherwise

For reference I’m on Android using Firefox so that may be different on ios
