Driver Tracking is a React Native (Expo, TypeScript) mobile app for fleet drivers, connected to a Dolibarr-based fleet management backend. Drivers sign in securely, view their assigned bookings, start trips, and update status from confirmed to completed. GPS location is tracked while a trip is in progress, with one-tap Google Maps navigation, trip history, push notifications, and emergency contacts. It supports light and dark themes with a clean, Uber-inspired design.
