I've been eagerly awaiting the release of berty for a few months now, but they have not made public the app yet. They have a closed beta, for a few months. And their build process for the android app is complex.
While berty is extremely interesting tech, I don't think it's quite ready to be on Hacker News yet.
My understanding is also that Berty is not fully production ready yet, however I have been following the project for a while and they seem to be going into the right direction. Other HNers might also be interested and who knows, the project might grow faster with more people involved.
This is an interesting topic though so a standard submission would work well.
