Congratulations! It's nice to see that we now have both Android (https:/mconversations.im) and iOS covered by usable and secure XMPP clients!
What I'm saying is that, if the goal is widespread usage, there are little small roadblocks before users can actually be using the app.
I cannot ask my family and friends to install F-droid or pay for an app that I'm not even sure they will like. So realistically, I will never mention it to them.
Maybe I misunderstood what is the target audience from the beginning. You're telling me it is the 0.0001℅ of the population that uses 3rd-party app stores, Linux, etc. That's fine too but it comes with its own limitations.
