  ABSTRACT: Objective: To evaluate the quality and inspect the usability of the Home and School Food Consumption (CADE) application. Methods: This was a cross-sectional study conducted with an online tool developed for mobile devices (smartphones and tablets) to assess the food intake of schoolchildren. Five specialists in Human-Computer Interaction (HCI) performed the heuristic evaluation of the application, also evaluating the degree of severity of the problems found. Five health professionals evaluated the quality of the application and answered a questionnaire, which included 21 questions. The frequency of heuristic violations, the most reported problems, and the average severity of the heuristics were estimated. Results: A total of 74 usability problems were identified, of which 17.8% violated the heuristic of flexibility and efficiency of use. Conclusion: The use of the application was considered easy to learn how to use by health professionals, who made several suggestions for improving the application.
