Jack Dorsey, the co-founder of Twitter and CEO of Block, released a free, new open-source messaging app in Apple's App Store on July 28 called Bitchat Mesh, or Bitchat. Dorsey unveiled the new app on X, formerly Twitter, in early July, calling it his "weekend project".

Twitter cofounder Jack Dorsey used Goose, Block's AI code editing tool, to develop his new messaging platform. He says it worked within a day.

Dorsey admitted that his new messaging app had not been reviewed or tested for security issues prior to its launch.

Earlier this month, Block CEO and Twitter co-founder Jack Dorsey unveiled a peer-to-peer, Bluetooth-based messaging app he put together. Now, anyone with a compatible iPhone, Mac or iPad (or even Apple Vision Pro) can try Bitchat as it's available on the App Store.

Jack Dorsey launches Bitchat, a decentralized messaging app built on the Bitcoin network, now available for iOS users.

Jack Dorsey's Bitchat is now available on the App Store, but security researchers have questioned the app's privacy claims.

The Bitchat Mesh app relies on Bluetooth for messaging friends and family. The app doesn't need you to register with a phone or an email ID.

Bitchat lets you chat with people nearby using Bluetooth and doesn't require an internet connection, email, or phone number. Messages are private and encrypted, and there's a Panic Mode to delete all your data with a triple-tap instantly.
