Introduction. The use of digital technology in the form of applications for health care has been growing and is a way of facilitating the food record and consumption studies. Applications are now available for the purpose of behavior change, helping individuals to ponder over food choices and identify fragilities in their routine. Objective. To evaluate the user’s perception on the usability of the Digital Food Guide (DFG), a mobile smartphone application with guidelines on healthy eating. Methods. Cross-sectional study evaluated the user perception of the application through Likert scale, built with 24 assertions organized in three analysis dimensions: DFG as intuitive and self-explanatory tool, as a promoter of healthy food choices and as a promoter of the transition to the appropriate weight. The instrument was assessed as to its reliability through the split-half method and validity in two stages. Results. The 22 assertions were validated; the reliability was 0.93; the average of the assertions in each dimension was 3.10; among the 80 respondents, 58.75% considered the implementation of the DFG positive. Conclusion. The application has good usability as perceived by users, considering the dimensions analysis related to its performance.
