"StepUP” is a mobile gamification of a fitness tracker designed for physically inactive children and adolescents in which every step and physical movement matters. With the application the players can not only keep an eye on their physical activity, but also earn rewards for engaging in it. Every user is represented by their virtual avatar which they can level-up by taking part in in activities such as walking, running and biking. As a reward for being active the players can relax by playing different minigames where they use their own avatar as a playable character. The minigames can be played with up to three other players so users can share the experience with friends.
