Public beta is open for Phantom Chat — iOS messenger I've been building solo from Western Australia.
The technical bit: every conversation uses a Signal Protocol Double Ratchet hybridised with NIST FIPS 203 ML-KEM-768 (Kyber). If either Curve25519 or the PQ KEM holds after a future quantum computer arrives, your message history stays sealed.
No phone, no email, no public directory. Invite-codes only.
