Virtual pet simulation games really aren't all that realistic when you think about it—you don't have to get your hands dirty, spend any money and you don't have to actually get off the couch and exercise. The Wokamon app keeps the best aspects of owning a virtual pet, like it being free, but it does require you to take your digital critter on a real walk.
Even the word "pedometer" sounds boring, but Wokamon makes step-trackers fun by combining it with caring for a virtual pet. Now, there's actually an incentive to get walking, since the more active you are, the more your Wokamon will gain experience and level up. In-app, multiple Wokamons can be unlocked, there are many worlds to explore and you can even customize your digi-pets.
