Maintaining a healthy lifestyle is an increasingly challenging task in modern society. The number of people with sedentary habits and poor nutrition is always higher. To prevent health problems and monitor lifestyle, there are many cutting-edge monitoring devices and applications. The problem is precisely the heterogeneity of the different devices. The project aims to develop an app that allows users to collect, display and interpret health data in the best possible way on a single platform. This allows users to analyze their health habits and conditions and then receive recommendations for improving their well-being. The frontend of the Well-being App, developed using Flutter, provides an intuitive but detailed user experience.
