Design Rationale

The color-coded to-do list app is designed with a focus on user experience and productivity. React was chosen for its component-based architecture, allowing for reusable UI elements and efficient rendering. The use of a Node.js backend with PostgreSQL provides a scalable and reliable foundation for data management. Color coding is a central feature, as it allows users to quickly categorize and prioritize tasks visually. The implementation of customizable settings ensures that the app can be tailored to individual user preferences, enhancing its utility across different use cases. The mobile-first approach with React Native ensures a consistent experience across devices, catering to users who need to manage tasks on the go.
