How it is built

Radar Flow is a cross-platform React Native application built with Expo and TypeScript. Supabase powers community reports, profiles, points, and realtime updates. Firebase supports authentication, analytics, and crash reporting. Google Maps provides mapping and route guidance, while SQLite and local caching support offline use. ONNX Runtime performs private, on-device vehicle diagnostics without requiring an AI backend.

Privacy and reliability

Location and diagnostic workflows are designed to minimize unnecessary data transfer. Secure storage, offline processing, background task handling, crash reporting, and clear permission controls help create a dependable production experience.

Availability

Radar Flow is available on the Apple App Store for iPhone and iPad.
