  10. Ensure proper SSL/TLS configuration for all communications

Design Rationale

The app is designed with a focus on user experience and efficiency. React Native was chosen for cross-platform development, reducing time-to-market and maintenance costs. The backend uses Node.js for its performance and large ecosystem, while MongoDB provides flexibility for storing varied user data. The smart reminder system is the core feature, designed to adapt to users' schedules, making it stand out from basic reminder apps. Security is prioritized with JWT authentication and data encryption to protect sensitive health information. The modular file structure and use of Redux for state management ensure scalability and ease of future feature additions.
