Just BAD

Looking for a way to keep track of books. Downloaded free version which supposedly is a full version with some ads. Thought if I liked it, Id pay to get rid of ads. However, when I open the app, I have a huge picture of Mariah Carey staring out at me. There is no way to get rid of it. I cant say if the app would be good because nothing works. Press any button and Im directed to a survey over and over again. So far, its been useless. Dont know how it can claim to be a top app, I appear to be the first to write a review.
