Phantom Chat Beta
Anonymous iOS messenger with post-quantum encryption
Phantom Chat is an end-to-end encrypted iOS messenger built around anonymity. Sign up with just a username — no phone, no email. Invite-code-only contact discovery. NIST post-quantum encryption baked in. Solo-built. iOS 17+.
Hi PH 👋
I'm Curtis — solo founder, Western Australia. I've been building Phantom Chat for 8 months and just opened the public TestFlight beta.
Three things I designed it around:
1️⃣ Post-quantum from day one — hybrid Signal Protocol + NIST FIPS 203 ML-KEM-768 (Kyber). Most messengers still don't have this; we ship with it from launch.
2️⃣ Anonymous sign-up — no phone, no email. Just pick a username. Contact discovery is invite-code-only.
3️⃣ Hardware-bound identity — your private key lives in the iPhone's Secure Enclave and never leaves it.
Free 14-day trial, no card. After that: Personal at US$14.99/mo or US$119/year.
TestFlight: https://testflight.apple.com/joi...
Always happy to answer technical questions — and if you spot something the marketing site overpromises, please call it out. I've already removed three claims that didn't quite match the code (Sealed Sender, iMessage PQ comparison, "air-gapped" servers) — I'd rather get those right than ship spin.
