Currently bullying is one of the most frequent problems that occur in educational institutions, for that with the help of technology we wanted to implement in this research as prevention of bullying. Therefore, the goal is to design a mobile application to prevent bullying in high school students. Likewise, the A.D.D.I.E. methodology was used: Analysis, Design, Development, Implementation and Evaluation. In the same way, a survey was carried out with 15 high school students from different schools, to know if they have ever been victims of bullying, perhaps by their other classmates. It is recommended in the future to continue research and develop technological solutions for this problem and other social problems that affect many countries.
