Jack Dorsey's Bitchat messaging app is now available on the iOS App Store, enabling users to send messages via Bluetooth mesh networks without internet connectivity within a 100-meter range. The app features a minimal interface with no login system and allows anonymous messaging to nearby users. Security researchers have raised concerns about the app's privacy claims, noting vulnerabilities that allow user impersonation. Dorsey acknowledged the app hasn't undergone external security testing. Additionally, fake versions of Bitchat have appeared on Google Play Store, prompting warnings about downloading unauthorized copies.
