B3 Runtime is an interactive, location-based quiz app where the users have to explore their surroundings while at the same time answer tricky questions. As the player moves throughout the checkpoints of a course, questions are prompted that the player then has to answer. By combining the best of two worlds: physical activities with intellectual stimulation, this app provides the users with an exciting experience! Continued use of GPS running in the background can dramatically decrease battery life.
