DeltaChat. I don't use it myself because it's built on electron (which basically excludes 99% of modern chat clients); but as it's technically an email client turned into a chat client, we can assume you're protected by PGP when writing to most users, and with the added effect of not needing to convince anyone to install anything since from their end it's just an email.

Someone here recently linked to this gem https://www.latacora.com/blog/2019/07/16/the-pgp-problem/
The article warns PGP over Email is a safety concern. They suggest Signal instead. (And several other tools to replace PGP)
PGP is unfortunately one of the only reliable ways to get encrypted messages into and out of China. Most of that article is kind of nitpicking IMO. The only major cryptographic issue is lack of forward security. The rest can be dealt with if you have a bit of know how.
Sure, I see where you are coming from. I used to be in favor of PGP as well, but I think I just was conditioned to it because it was everywhere, eg Linux repositories. The argument I found more convincing in this article is that PGP is a swiss-army knife. You might want to use it in an emergency, but professionals have special tools for each different task. In fact, the article suggests very nice alternatives for each task: Encrypt with age , sign with minisign. Two different tasks, two different tools, no need for a web of trust. Just for the arguments sake why do you think that PGP is worth it given the burden of entry?

If you really need it to be secure and private, and are communicating mostly with known acquaintances within a reasonable radius, with low bandwidth requirements, LoRA with encryption is the best bet.
It is a higher bar of entry but at least you can be confident your messages won't be intercepted in any useful form.
I have been interested in trying out LoRA and just need to get some devices built. Though I am not as concerned about the super privacy part (thought that is nice). I am thinking that it would be good for emergency situations like shit that has happened with the south-east. Even if the communications would be limited to text, shit is good as long as I can use simple solar panels and battery banks.
Meshtastic can do this, and leverage other nodes as relays.
Have you used it before? I'm curious about how it works. I don't personally have a use case but it seems very cool.
I have 2 heltec v3 nodes, I setup an encrypted channel between them... I can get good distance but I have a very good network run by others in the area that I piggy back on.
If you have line of sight you can go pretty far
I don't really have much of a use case though, it's just playing around with the tech for fun.
Signal, Threema, SimpleX.
Your source is ridiculous. Please educate yourself about more how Signal works.
