The biggest block I find to uptake of these messengers and call apps that so often come and go is the lack of mobile applications. Until there’s an Android and iOS app, my friends and family won’t use it.
I don’t like it, but it appears to be the world we’re in now.
It seems like it already has an android app? https://play.google.com/store/apps/details?id=cx.ring
Could not find anything for iOS: https://ring.cx/en/download
There’s a source code repos, but no release. https://gerrit-ring.savoirfairelinux.com/#/admin/projects/ring-client-ios
