People interested in BitChat should download it just so you have it in case it gets popular or you find someone to use it with. I tested it and it's surreal to text without WiFi or cellular.

Bluetooth chat apps already exist. I used a really shitty looking (but functional) one called Berkanan that I found by searching the App Store for a Bluetooth chat app to talk to friends on ryan air flights where we weren’t sitting together across Europe last year.

I think FireChat was the first one, in 2011.

		I remember when sending messages and files through IR was a standard default feature in (dump) phones two decades ago. It is a bit sad how technology in some ways regresses when certain anti-incentives apply.
