Just installed the app a couple of days ago when I listened to this podcast from Opt-Out: "SimpleX chat and how privacy aligns with the future of computing w/ Evgeny from SimpleX" https://overcast.fm/+vSwTqJjw4

Very interesting stuff!

You can also run your own server/relay: https://github.com/simplex-chat/simplexmq
