This project is a mobile application version of the Doctora healthcare platform, designed for convenient doctor appointment booking on smartphones. The app features intelligent auto-matching that suggests suitable doctors based on specialty and availability, manual doctor selection, real-time schedule viewing, and appointment management. Patients can register, search for doctors, book appointments, and track their appointment history, while the system provides instant notifications and updates. Built with React Native and Expo for cross-platform compatibility, with backend integration to the Doctora API system. (System-oriented mobile application project)
