I cam from Parler (Don't get me wrong, I hope they get it figured out and get things back up and running) I have been heavily exploring these new platforms. To be honest, I would love anonup to release a working app. I know WeGo has an app but it's also not functional. Being tied to a browser app is less then ideal when it comes to notifications and ease of access.
I think alot of these platforms would take off if working applications would be released.
