Plural Star

The core mobile app (React Native, iOS + Android), live on both app stores with roughly 5,000 users. Front tracking with history and statistics, member profiles with custom fields, journals, polls, system chat, an internal mailbox, medical tracking with cross-platform reminders, a relationship map that scales to systems with thousands of members, and importers for seven other plurality apps so no one is locked in. Local-first storage with encrypted on-device backups; the Friends & Sync networking layer is end-to-end encrypted (Ed25519/X25519, tweetnacl) with the relay treated as hostile — it only ever sees opaque blobs. Fully translated into 17 languages with screen-reader accessibility throughout.
