    There is already a really good foss app that does exactly that, it’s called briar and is as secure and private as it gets. The downside with p2p communication apps being, that they eat your phones battery for breakfast. Still a good option for activists or journalists I think. It’s a good way to get around the “server in the middle” problem. Still more convenient to run your own (xmpp) server at home imho…

      ** for Android (and Windows/macOS/Linux) but not iOS.

      And apparently never going to be as some key component is written in Java. Other technical obstacles should be solvable (like f.ex. getting continuous running in bg by exploiting location services like iSH can do)

    I once did some programming on the Cybiko, a device from 2000 that could form a wireless mesh network with peers. The idea was that you could have a shopping mall full of teens and they’d be able to chat with each other from one end to the other by routing through the mesh. It was a neat device!

      I wanted a cybiko so bad as a teen. It seemed like it would be so cool if everyone I knew bought one. Of course no one did, but I still think they are awesome.

    Have a look at meshtastic. Yes, you do have to get a separate device, but range on it can be several tens to hundreds of miles depending on the mesh density.

    If you’re in Bluetooth range can’t you chat with your mouths? Or is it for secretly chatting when you’re in a group of people? I don’t get the use case.

      It’s not about you being in bluetooth range of the person you want to talk to, it’s about all the people sitting in between you both that pass the message along without touching the internet.

      So you can be on a cargo ship, or on a remote island, with 20 other people and all use chat. If 1 person has internet, then you can all chat globally as well.

      It’s the same basic method of how airtags work. Everyone with an iPhone connects to the airtag and passes data to Apple. It’s just done in the background, so users don’t ever notice.

      Could be useful on a plane: If you have different seats than someone and don’t want to pay for your airline’s ridiculous data prices. Although, most airlines I fly on(american, delta, air canada, united) all have free RCS/Facebook/Whatsapp, but not necessarily Signal, Telegram, Matrix, or your preferred secure service.

      Bluetooth ranges are quite large now.

      But an example even if someone is a foot away would be a concert or event where it’s to loud.

      I have no idea if this is correct. But imagine if you have a setup like Apple’s AirTag. Except when you receive a signal (message) you also relay it to whoever’s path you cross for the next X amount of time. The more people using the app the bigger the mesh network gets.

    Neat idea 10 years ago “discovered” recently by a tech bro who thinks he’s the first one to think of it. He got his clicks, I guess.

    I’m happy to see a niche decentralized thing from Jack more than if it was another commercial start-up. And I have nothing against yet another bluetooth chat. But I’m not impressed. In the whitepaper nothing is written about spam protection, so it wouldn’t work as a reliable P2P app at scale. And the UI… It’s mere a toy for Jack’s personal nostalgia about “the good old times”. And nostalgia driven development doesn’t work in general, I would say.

    messaging app that works over Bluetooth mesh networks. No internet

    So he’s made a shitty version of Briar and crammed crypto into it?
