Jack Dorsey launches Bitchat, a messaging app that works without internet, servers, or accounts

Jack Dorsey has launched Bitchat, a new peer-to-peer messaging app that operates over Bluetooth mesh networks without internet or central servers. The app, developed in a weekend, doesn't require user accounts or personal information. Messages are relayed between nearby devices, creating a network that can extend up to 300 meters. Bitchat offers privacy-focused features like disappearing messages and password-protected group chats. The beta version quickly reached its 10,000-user capacity on TestFlight, with plans for wider release pending review.
