Anyone with experience using Jami? tried using it recently, but could messages were not being received, notification for incoming calls at times were hit and miss. Seems to be updated quite frequently on F-Droid.

If we told just anyone, it wouldn’t be private!!!

Srsly any phone app is inherently insecure because the phone itself is insecure. And there’s lots of metadata leakage, like the phone broadcasting its location. There is no “go to app”. It all depends on what you are trying to do and who you are trying to communicate with.

Matrix but thinking about XMPP as Matrix leaks a loy of metadata and is pretty slow and new.

Neither Matrix nor XMPP are software, those are protocols. Alsp, there is no point in specifying that XMPP is encrypted without doing the same for Matrix, since you can exchange plain text messages there too.

As for the actual question, here you go: https://www.privacyguides.org/en/real-time-communication/#criteria

I’ve heard great things about matrix, but I only really use signal. It’s the only private messenger that’s convieniant and simple to understand for non tech savy people to switch to (at least in my experience)
