Health meansure: plataforma digital integrada para acompanhamento nutricional com foco em experiência do usuário

Abstract

This work presents the development, evaluation, and application of HealthMeansure, a digital health system designed to support nutritional follow-up, patient engagement, and data-driven decision-making. The study addresses the growing prevalence of obesity and the demand for scalable technological solutions capable of integrating patients, health professionals, and administrative users in a unified ecosystem. The system was built using Flutter for the mobile application, React.js for the web interface, and Firebase as the cloud infrastructure, incorporating authentication, real-time synchronization, data storage, notifications, and dashboards for monitoring user behavior. Methodologically, the work adopts the TDCA data pipeline model and includes UX evaluation through the System Usability Scale (SUS). Results demonstrate that digital strategies can enhance communication, adherence, monitoring, and usability in nutritional care. The project contributes technologically, scientifically, ergonomically, and socially by offering a functional, scalable, and user-centered solution for digital nutrition monitoring.
