TL;DR

Jack Dorsey just dropped Bitchat, a weekend-built messaging app that runs entirely over a Bluetooth mesh—no internet, servers or accounts required. Messages hop device-to-device, vanish by default and live only on your phone, making it super private and censorship-resistant.

It supports one-on-one chats plus hashtagged, password-protected “rooms” and even store-and-forward delivery for offline users. The iOS TestFlight beta hit its 10,000-user cap almost instantly, and Dorsey’s promising Wi-Fi Direct support and a broader release next.
