Baffled

I downloaded the free version to see if I liked this app before I downloaded the paid version. I looked at the signs and am completely confused: purple, number 8, alligator??how are these signs useful when youre just beginning sign language with a child? I realize the paid version would likely have more of the signs I need to start (hurt? Eat?), but Im so irritated Im thinking Ill pass. Wouldnt it be more constructive to give some of the first useful signs in your free version in order to get your users "hooked" so that theyd want to buy more?
