I mean...I guess thanks for the stepping off point? Android has the Briar Project, which couldn't be distributed for iOS due to Apple's license fuckery. I'm at least curious enough to look through this and see what they've done different.
I think the most useless part of this is using BT only which has a range of what...40ft?
There are plenty of situations where that’s useful, especially if you can have group chats with images. Think airplanes, weddings, concerts, sports arenas. And if you have meshing and store and forward when nodes are moving around, you can cover a large area that may not have internet. It’s a legitimate tool that no one has done right yet - and as apple only, this is t yet either.
It's definitely limiting. LoRa wan meshed network is more useful. But most people don't have a LoRa capable device. I could see something like this at a protest or public event at least. If there were enough nodes in the area the network could span hundreds to thousands of feet with the right conditions. But that's a big ask ATM.
