The Sporty Mentor project (ERASMUS+) app uses mentoring and sport as tools to stimulate change in young people with challenging behaviors. The app presents a model that promotes and ensures children/ young people are listened to in a child-friendly, positive and informal environment. We want to address the lack of physical activity in adolescents. Through the app, users can be introduced to new technologies & new ways of interaction as it will involve the mentors/mentees & invite them to share & challenge each other with play-full activities.
