Jack Dorsey Launches Bitchat: A New Messaging App That Works Without Internet

Twitter co-founder Jack Dorsey has unveiled a new messaging app called Bitchat that can function entirely without an internet connection. Designed for privacy and decentralised communication, the app allows users to send encrypted messages via Bluetooth without relying on mobile networks, Wi-Fi, or servers. Currently available in beta for iPhone users through Apple’s TestFlight platform, Bitchat is already gaining attention for its unique offline messaging model.

Bitchat Uses Bluetooth Instead of Internet

Unlike apps like WhatsApp or Telegram that rely on central servers and require user registration, Bitchat operates using Bluetooth Low Energy (BLE) mesh networking. This means nearby devices form a temporary cluster and pass encrypted messages along. As users move, they can help relay messages over longer distances by bridging clusters — a technique similar to digital walkie-talkies.

The app works within a Bluetooth range of around 30 metres, but with enough connected users, messages can travel far beyond that limit. Since it doesn’t need mobile data or Wi-Fi, Bitchat is ideal for use during internet blackouts, in disaster-hit areas, or in places with restricted digital access.

Focus on Privacy and Anonymity

One of Bitchat’s standout features is no sign-up process — users don’t need to register with their phone number or email, making communication anonymous by default. All messages are end-to-end encrypted and stored only on users’ devices. These messages are automatically deleted after a short period, adding another layer of privacy.

Limited iPhone Beta for Now

Bitchat is currently in a limited beta release on iOS via TestFlight. The app quickly reached Apple’s 10,000 tester cap, reflecting high early interest. Jack Dorsey also released the app’s whitepaper and shared the beta invitation openly.

The development team is focusing on battery optimisation and relay stability in this testing phase. Future updates will likely include Wi-Fi support for sharing images and videos and possibly expansion to Android devices.
