Bitchat uses Bluetooth mesh networking for peer-to-peer chats—ideal during outages or in remote areas.
No sign-up, email, or phone number required; messages are end-to-end encrypted and auto-delete.
Messages relay via nearby devices, with no central servers, making the app fully anonymous and offline-friendly.
Twitter co-founder Jack Dorsey has unveiled a new messaging app that functions without any internet connection. Called Bitchat, the app uses Bluetooth Low Energy (BLE) mesh networking to enable encrypted, peer-to-peer messaging without having to require any Wi-Fi, mobile data, or centralised servers. Currently available in beta via Apple’s TestFlight, Bitchat has already reached its 10,000-user testing limit. The app is designed for iPhone users, with plans to expand support and features in the coming months.
SurveyUnlike other messaging platforms such as WhatsApp or Telegram, Bitchat is entirely decentralised. There’s no user registration, no email or phone number required, and no central server storing conversations. Plus, messages are end-to-end encrypted, stored only on user devices, and will automatically be deleted after a short time. Here’s how Jack Dorsey’s new messaging app works.
How Bitchat works
Bitchat relies on Bluetooth Mesh Networking, where localised clusters are formed by nearby devices (within ~30 metres). As users move, their phones act as message relays, helping deliver messages across greater distances without requiring traditional network infrastructure.
Notably, the app does not use any form of internet connection, including Wi-Fi or mobile networks, making it especially useful in emergencies, remote areas, or during internet shutdowns.
One of the key highlights of the newly launched messaging platform is that it does not require any central servers or account registration, helping users to maintain their anonymity.
Bitchat availability
Dorsey has released the app’s whitepaper and public beta invitation exclusively through Apple’s TestFlight platform. It has hit the 10,000 testing cap just after its launch. Currently, the beta version of the app is focusing on battery optimisation and reliability. With the final release, the app is also expected to support Wi-Fi protocol to enhance bandwidth and enable the sharing of rich content, such as pictures and videos.
Additionally, Bitchat may expand support for more platforms as well in the future.
