Syrnik

Messaging and calls, built from scratch.

A full messenger: one-to-one and group chats, voice messages, media and file sharing, reactions and forwarding, plus voice and video calls with a native incoming-call screen. A ground-up build of the hardest consumer app category, with realtime sync and a local cache so chats open instantly.
