This book tracker app. It is very simple, which I like. It does just want I want and not much more. It keeps track of several books that I read at once and displays a percentage complete which I find helps to motivate me to finish one which otherwise is a problem for me. It also allow entering a book by scanning it or manually entering it and setting the total number of pages.
