Enigma
A privacy-focused native chat app — Nearby discovery plus an opt-in, truly end-to-end-encrypted private tier — with one Rust crypto core shared across iOS and Android.
- Two clearly separated chat tiers — an open cloud tier that syncs across devices and keeps full history, and an opt-in Private tier that is end-to-end encrypted so the server can only relay opaque ciphertext
- Nearby discovery — find and message people physically around you within a radius or across a city, distinct from the cloud-synced social graph
- One shared Rust security core for the crypto and message protocol, written once and bridged into both iOS and Android via UniFFI — no duplicated, divergent crypto implementations
