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.
Bridgefy was used more during protests since it’s available on both iOS and Android, while Briar is Android only.
Bridgefy seems to require an online account to use. Brair requires zero obline accounts, and even allows sharing the apk to nearby devices without internet.
Edit: Yea, just checked… Bridgefy requires an internet connection the first time you launch it. Not good…
