NutriApp: um protótipo de aplicativo nutricional com interface otimizada para nutricionistas

Abstract

The increasing obesity rates and the demand for digital solutions in nutrition highlight the need for efficient tools to support professionals in this field. This work presents the development of NutriApp, a prototype nutritional application designed exclusively for nutritionists, aimed at optimizing patient registration, personalizing diets, and facilitating nutritional monitoring. NutriApp prioritizes usability, simplicity, and personalization, addressing specific demands from nutritionists through an intuitive and user-centered interface. The applied methodology included a literature review on interface design, market research, and interviews with two nutritionists of distinct profiles: one more experienced in using technology and another with less familiarity with digital tools. These interviews helped identify practical challenges, such as usability issues and limitations of current applications (software 1 and 2). Based on this data, prototypes were developed using the Figma tool, incorporating features such as food equivalence tables, nutritional plan personalization, and interactive resources. Although a recipe module and functionalities for patients have not yet been implemented, these are planned for future versions of the application. Usability tests conducted with the nutritionists highlighted a significant reduction in the time required for routine tasks, such as patient registration and diet creation, increasing productivity and improving user experience. The results indicate that NutriApp has the potential to transform nutritional practice by integrating technology in an innovative way, promoting agility and effectiveness in services. Future implementations, such as backend services and data storage systems, promise to add functionalities, making the NutriApp prototype a tool that meets market demands.
