So my friend group has been looking for alternatives for a while now that feel like discord, works on mobile and desktop, and has voice chat. I use Signal but the UI is very different from Discord. I've had very mixed experiences with Element + Matrix, Element keeps crashing on mobile, and while voice chat kinda exists in Element it's not been great imho. I looked into hosting Rocket.chat, Zullip, and Mattermost but from what I recall voice + mobile were either missing or paywalled at a per-user price. Any recommendations?
