Score: 7.8/10 (Innovation: 8, Technical: 8, Documentation: 8, Utility: 7)

Occulta is an iOS app that exchanges cryptographic keys in person over UWB and lets you encrypt files to those contacts without servers, accounts, or phone numbers. It combines hardware-backed keys, post-quantum protection, and duress-resistant secure mode to fill a real gap for high-risk privacy users.

Target audience: security-conscious professionals, journalists, activists, and privacy-focused iOS users
