BitWalking: generate money by walking?

BitWalking just released its app (Android only for now), it can be downloaded here:

The app seems to be in its early stages so there aren't lots of features or details yet.
You can try it out, start harvesting steps and generating Walking Dollars (W$) in the meantime.
