I use element.io

I'm using Element

when accessing matrix I was using SchildiChat, a fork of Element with improvements

closed my own instance some time ago, but thinking on running it again soon, maybe using Conduit or Dendrite instead of Synapse

+1 on SchildiChat here as well.

I used to use FluffyChat but it would corrupt its internal SQLite database randomly. That happened a couple of times so I just stopped using it entirely.

I've been using Matrix for several years now, and am very happy with it, and with the progress that it made.

I have one instance just for me, which I use for general chatting, as well as for some light experiments (I'm toying with some client development and trying new plugins or appservices now and then).

I have another, private and undfederated instance for family comms. I set it up at the very beginning of the Covid-19 era, when nobody knew how long and how severe will the travel restrictions be, and we've been using it heavily ever since.

Ive liked fluffychat on Android, but I'm waiting for elementx to come out honestly,

I use chat.mozilla.org

Same here actually. Haven't tried Matrix at all and use Signal daily for regular messaging. Matrix looks promising though. Looking forward to seeing what instances people use our if self hosting is common.
