is an outdoor fitness app developed by a group of Wellesley students that uses the threat of killer bunnies to get kids ages 8-14 outside. Created with App Inventor, the game tracks players as they physically move around capturing virtual escaped magicians rabbits. The designers used the location sensor to determine whether the player is running, and if the player does not move fast enough, an alert encourages them to Walk Faster! The design team created Bunny Bolt to apply for a Game ON! Challenge Grant.
