The Walk – Fitness Tracker and Game tracks every step the player takes in this new fitness game from the makers of Zombies, Run! A bomb goes off and players are given a package that could save the world, though they must walk the entire length of the UK to survive.

The app uses a step counter that tracks every walk and run the player takes and displays it on a map for their viewing, and it also adjusts the difficulty to each individuals fitness level. It comes with 65 episodes and 800 minutes of audio to experience during this journey.
