In this study, a mobile application based on gamification was developed to support the learning of fractions in fourth grade students. Using the SCRUM methodology, 4 sprints were carried out and tools such as Unity, Firebase and C# were used. To determine its impact, a pre- and post-test research design was used with a group of 21 fourth grade elementary school students from an educational institution in Chiclayo-Peru. The results showed a successful gamification, with an attractive design and high satisfaction in usability. In summary, gamified mobile applications have great potential to improve learning. © 2023 IEEE.
