Bitchat, a messaging app created by Twitter and Block founder Jack Dorsey, is now available for download on the iOS App Store. Dorsey mentioned that he developed the app’s basics over a weekend in early July.
Operating through Bluetooth mesh networks, Bitchat allows users to exchange messages with others within Bluetooth range, typically around 100 meters, even without cell reception or Wi-Fi. The app features a very minimalistic UX, with no login system and users immediately led to an instant messaging box where they can see nearby users’ messages and set their display name.
The concept of Bluetooth-powered messaging apps is not new, with similar apps being popular in environments like music festivals with limited cell service or areas affected by natural disasters. Bitchat was promoted as a secure and private messaging platform during its beta release, although security researcher Alex Radocea pointed out potential flaws in the app’s security, such as the ease of impersonating others.
Dorsey acknowledged that Bitchat had not undergone an external security review and may have vulnerabilities. Concerns about impersonation extend to the app itself, with multiple fake Bitchat apps appearing on the Google Play store. Dorsey has not directly addressed these fake apps but has warned users to be cautious and avoid downloading fake versions of Bitchat from the Google Play store.
