The Challenge
African WhatsApp users have no real indigenous alternative: existing apps assume fast, cheap data, dont ship with major local languages, and give organisations and churches no channel/push-to-talk tool built for group broadcast rather than one-to-one chat.
Our Solution
A FastAPI + WebSocket backend (SQLAlchemy, LiveKit for calls) paired with a React Native/Expo mobile app. Messages queue offline and sync on reconnect, images auto-compress, a data-saver mode is on by default, and the app ships in English, French, Swahili, Yoruba and Hausa out of the box.
