So you've bought a Fitbit. Now what? How about turning it into an RPG?
FatChicken Studios has released FitRPG; a game that turns the data collected by your Fitbit into your character’s strength, hit points, endurance, dexterity, and experience. Your character will receive quests and battle monsters to receive gold and experience. With that loot you can buy weapons, potions, armor, and other accessories, then battle your friends. The fittest player gets to steal their opponents gold and experience! Don't have a Fitbit? Not to worry, FatChicken Studios says they plan on having FitRPG integrate with Jawbone and other fitness trackers pretty soon.
FitRPG sounds like it might be a fun way to stay motivated about working out when you'd rather be gaming. You can pick it up on the App Store for free.
