Design Rationale

The Smart Stress Ball Usage Tracker app is designed with a focus on user experience and data-driven insights. The choice of React Native allows for efficient cross-platform development, ensuring a consistent experience for both iOS and Android users. The backend uses Node.js and MongoDB for their flexibility and scalability, which is crucial for handling real-time data processing and storage.

Bluetooth integration is essential for seamless communication with the smart stress ball device, while robust data visualization tools help users understand their stress patterns easily. The gamification elements and achievement system are included to increase user engagement and motivation for regular stress management.

The app's architecture is designed to be modular and scalable, allowing for easy addition of new features and integration with other health and wellness platforms in the future. Security and privacy considerations are prioritized throughout the design to protect sensitive user data.
