Bitchat might not work as intended though, and here is why.

Bluetooth communication can be captured using specialized hardware and software tools designed for packet sniffing and man-in-the-middle (MITM) attacks.

nRF Sniffer for Bluetooth LE, Ubertooth, or Gattacker can be used to monitor and capture traffic between devices. It's definitely more secure and depends on the Bluetooth version and encryption, but it's not immune.

So as the app and its code have not undergone external security review, and the project's own developers explicitly warn against using it for production or high-risk communications, its security is still under review.

A major flaw allows attackers to impersonate trusted contacts by exploiting the "Favorites" function, and a potential buffer overflow bug has been reported.

For here and there, it’s awesome to use. But for the world that needs it (I.e Iran’s authoritarianist regime shutting off internet), these vulnerabilities make a huge impact.

PS- would appreciate a reply back in the DMs lol
