Twitter co-founder and former CEO Jack Dorsey’s Bluetooth messaging app now available on App Store

Jack Dorsey, co-founder and former CEO of Twitter (now X), has officially launched his highly anticipated Bluetooth-based messaging application, BitChat. The WhatsApp rival is now available on Apple App Store for download. Designed for offline communication, Bitchat uses Bluetooth mesh networks to let users chat with others nearby—no cellular or Wi-Fi connection required. Dorsey reportedly coded the app’s foundation over a weekend in early July. The app features a minimalist interface with no login system; users simply open the app, set a display name, and begin messaging anyone within Bluetooth range—typically up to 100 meters.
