Gravity Guy is one of my favorite iOS games on the market, so there's no contest for today's freebie. The gravity-shifting runner game costs nothing right now, and it's easily one of the best Apps that FAotD has ever featured.
The bright graphics, cool music, and increasingly challenging gameplay makes this one that should not be missed. In fact, if you don't get it, you're a damn cock. So sort it out!
