We all know Signal, Matrix, Telegram, SimpleX, etc… But if you can’t access the internet you can’t communicate. Pretty logic. But would it be possible, at least theoretically, to create an app that permits to message people even if the internet goes down?
It might be a dumb question I really have no idea to be honest.
yes, a lot of people were using those kinds of apps during the free hong kong protests, they go from device-to-device with no internet in between.
No idea what the app is called, but apps like those exist
