End of Degree project

Supervisors: Jesús Fontecha & José Bravo


At present, and especially in developed countries, there is an increase in diseases associated with bad nutrition such as obesity, diabetes, cardiovascular disease or protein-calorie malnutrition due to increased consumption of processed, hypercaloric or low-nutrient foods . This Final Degree Project o ers users BeHealthy, a caloric and macronutrient tracking Android application, helps with the creation of personalized diets based on the characteristics of the user and allowing them to keep a better control of the food consumed. The food information has been obtained from an open database (Open Food Facts), so that the user can search through more than 27 thousand records. All this data has been saved in a remote database with the rest of the application data. The new technologies allow us to develop applications to help the user in performing some tasks. For this reason, the application allows the user to add food intakes using NFC technology and can create a personalized food catalog with NFC tags, decreasing user application interaction. In the project development, a user-centered agile methodology has been followed, the users lling some usability questionnaires at the end of each iteration, using the System Usability Scale (SUS), whose nal balance has been positive.
