Does it exist? I miss when YikYak was for hometowns and you could view other cities or comment/post there if in range. I don’t like its current state after coming back. It was like the neighbour apps but less facebooky with a crowd under 50, was the ultimate local news source.
I’d love an app like that.
A true app or program though, running on devices. Something that could set up ad hoc networks or relays. Locally it shouldn’t be reliant on the Internet.
Sounds like meshtastic
Or Reticulum Network via RNode (/its firmware)
