I was happy with Cloudfanatic.

Yeah unfortunately iOS is very stingy with battery. Thankfully there’s a few apps that use apples push and ejabberd supports it. I haven’t tested them in a while tho since I’m on android.

Mattermost is great and I’m pretty sure they have an iOS app. I don’t believe the messages are encrypted on MM, but if you’re running the infra it’s not too big of a deal IMHO.

I run ejabberd for myself and my family/friend and use conversations on android. Mattermost I would say is the most like discord. I run one of those as well and love it.
