It would be good if it had alot of tasks that are given by the app accordingly to your interest, and even recommend books, etc. Also if there was a competitive mode where you can see what level other players are, and that to level up you have to do certain things that can be verified somehow (for example, read book requires a picture of a book with your face, or run requires a tracking through the GPS to actually verify yoy ran) in this way it can even be competitive
