Nice app, you can begin reading the book and there are extra features like a puzzle and an English version. What I but very into. With a paid app is very bothering advertising. At the end you come to a bookshelf and children who so use this app, parents, the book will surely see more than once to be asked every time, "Do you know this Pixi books"? With one click you can then be purchased, you should have not set Parental Control. And even with Parental Controls you have discussions if you still can not buy the other books.
