Score: 4.0/10 (Innovation: 5, Technical: 3, Documentation: 3, Utility: 4)

Phantom Chat is an iOS messenger beta that claims to implement NIST post-quantum encryption (PQXDH). The project is interesting due to its focus on future-proof cryptographic security, but the README only contains generic TestFlight instructions with no technical details or code, limiting its evaluation.

Target audience: backend devs
