Not cool...
Having said that...if the developer fixes the bug and is up-front about the fact you're only buying the trial version of the app there are some cool features. The book comes with four paint pages for kids to pick colors and paint-bucket fill the coloring page. The animations on the story book pages we were able to view were cool as they create trails wherever the child moves their finger on the page. I do wish there was an option for an audio story book as my children aren't reading on their own yet so couldn't fully enjoy the story on their own.
