Easily the worst app ever

This app does not function. Bad spelling errors, random text, what the? You cannot see the bottom of the page, it is cut off and it is impossible to scroll down to see it. Also the toolbar at the bottom disappeared now and I cant get it back to go to the table of contents.
This needs an update -fix the book and a planner. A 10$ rip off
