A peer-to-peer (P2P) mobile messaging app with no central server, built with a teammate. We compiled our Go communication core for Android and iOS with Gomobile and connected it to a Flutter app. Messages are encrypted with AES-256-GCM and sent directly over WebRTC, falling back to UDP; if they can't be delivered, the encrypted packet is left in a mailbox on Firestore. It supports one-to-one and group chats, file sharing, delivered/read receipts and online status.
