Bitchat, a messaging app created by X (formerly Twitter) and Block founder Jack Dorsey, is now officially available to download from the iOS App Store, providing a new experience to iPhone users.
Bitchat operates through Bluetooth mesh networks, which results in users being able to send messages to others within the range of Bluetooth connectivity — usually around 100 meters — without cell reception or a Wi-Fi connection.
According to the company, the app is developed in a way that there is no log-in system, and you’re immediately brought to an instant messaging box, where you can see what nearby users are saying and set your display name, which can be changed at any time.
Dorsey advertised Bitchat as a secure, private messaging platform when it went live for beta use earlier this month.
However, in a blog post, security researcher Alex Radocea pointed out that it’s easy to impersonate other people within Bitchat, calling into question how secure the “vibe-coded” app really is.
“In cryptography, details matter,” Radocea wrote. “A protocol that has the right vibes can have fundamental substance flaws that compromise everything it claims to protect.”
Later, Dorsey admitted that the software had not been subject to an external security review and thus may contain vulnerabilities.
Currently, Bitchat can be downloaded for iOS via the App Store, or it can be loaded onto an Android device by downloading the app from GitHub.
However, the Google Play Store hosts multiple apps that appear to be pretending to be Dorsey’s app, which have garnered thousands of downloads.
Dorsey has not directly addressed the fake Bitchat apps on the Google Play store, but he did repost another user’s X post that said that Bitchat is not yet on Google Play, and to “beware of fakes.”
