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.
