Where is the explanation?

I bought this and really dont know what it does. Does it level? I did not need that. I needed to take better pictures when the camera was moving. They do not mention that in their website. I looks like it does that. Does it? In other words, the documentation and the explanations are very terse and non helpful. This may be a great app. I wish people would spend some time writing what their apps do.
