Kind of limited due to there not being an iOS version, but Briar is pretty decent. It was made to be usable in repressive areas by press and other groups, as well as in areas where bad weather has taken out cell and regular wifi. Can be used with phone data, but also offline via ad-hoc wifi and bluetooth. But stuff like Signal and SimpleX are more overall useful to more people (and I think SimpleX also supports offline local immediate area of each other like wifi and bluetooth but I don't remember atm).

I don't think Briar could be on iOS due to Apple TOS.
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.
I guess we could make one using newer FHE-RAM techniques and some edge case handling.
reasons not to use signal
Has this been updated in awhile?
Signal, Threema, SimpleX.
Your source is ridiculous. Please educate yourself about more how Signal works.
