Optimization and Expansion of a Wellbeing App: Improving User Experience, Data Management, and Health Knowledge Delivery

As life expectancy increases worldwide, a growing number of individuals are living into advanced age. However, this longevity is often accompanied by multiple chronic health conditions, negatively impacting the quality of life for many elderly individuals. The rapid aging of the population, coupled with an increasing prevalence of chronic diseases, underscores the urgent need for tools that not only extend life but also enhance well-being during later years. This thesis focuses on addressing this challenge through the enhancement of an existing wellbeing mobile application aimed at promoting healthy lifestyle habits. The project primarily focuses on two areas: improving the app’s User Interface (UI) and User Experience (UX) to create a more intuitive, user-friendly platform, and optimizing the backend structure to ensure efficient data management and scalability. A redesign of the app’s theme and layout was carried out, adopting a modern dark mode interface with enhanced readability and interaction. Key user engagement features, such as knowledge pills and quizzes, were rebuilt to provide more concise, engaging, and personalized health information to users. Furthermore, the navigation flow was restructured to improve gesture detection and back-navigation functionality, making the app easier and more intuitive to use. Backend improvements included consolidating how data is stored and retrieved, particularly for activity, sleep, and quiz information. The use of Fitbit as the primary data source improved data consistency, while the restructuring of database elements optimized performance and storage efficiency. These changes also enabled better personalization for users, storing essential data such as health goals and completed knowledge pills. Overall, these modifications aim to create a more robust, scalable, and maintainable platform that supports users in their pursuit of healthier and longer lives.
