This research article presents a proposal for prototyping a mobile application for adolescents, helping them to know more about their sexual health. This application aims to disseminate knowledge and particular attention to these adolescents that these issues should not be a matter of shame but rather something that will help them to be able to cope in today's society. That is why this application is presented in a dynamic way with interactive games, multimedia experiences and attention through a chat. The idea arose from a problem that was in northern Lima, Peru. Many adolescents have little knowledge of these issues and are exposed to sexually transmitted diseases or early pregnancies, and as a result, they stop studying or worse, die. The development of this project was carried out using an Agile Methodology called Scrum, since we had ideas or requirements of the functionalities that the application required in a short term delivering an already functional design. That's why Balsamiq Mockups was used to visualize how the design would look like by sprint of the stories that were held together. Therefore, in order to consolidate this research, a survey was launched among adolescents in Lima, Peru, showing the results we expect for this research.
