Bitchat Is a New Private Bluetooth Messaging App that Doesn’t Need the Internet – Here’s How It Works

JUL 28 – Bitchat offers decentralized, end-to-end encrypted messaging over Bluetooth without internet, attracting over 100,000 early users during its beta phase, Jack Dorsey announced.

  • Jack Dorsey launched Bitchat Mesh in early July 2025 as a Bluetooth-based messaging app available on the iOS App Store that works without internet.
  • Dorsey created Bitchat over a weekend and announced it as a secure, private platform, but he admitted it had no external security review and may have vulnerabilities.
  • The app relies on Bluetooth mesh networks to send messages peer-to-peer within about 100 meters, without servers or data collection, but testers found users can impersonate contacts.
  • TechCrunch reported on July 9 that Bitchat lacked an initial warning about security risks, and Dorsey warned against downloading fake Android versions from Google Play where impostor apps exist.
  • Bitchat’s lack of mass users and unresolved security issues suggest it should not be used for sensitive communications until independent reviews confirm its safety.
