iOS: Gamifying your workout routine is a great way to incentivise yourself to get things done, and Six to Start, the makers of Zombies, Run have a new app built just for that. Dungeon Runner uses motion tracking to see what you're doing, track your workouts and reward you with a little dungeon crawl.
Dungeon Runner uses motion tracking to track your reps in a variety of exercises. To use it, just set up your iPhone or iPad about 1.8m away, point it at yourself, then follow the on-screen instructions. If you're looking for a temporary way to spice up a dull workout, Dungeon Runner does the job.
