Pretty good I'm a new user and have scanned almost two hundred books from my collection  and added several via search. I love what this app offers for detail about the books and I love that I can edit and add more info  and track what I've read. The only wish I have at this point is to be able to have the books stored off my phone so I can sync across devices or look them up on desktop. Other than that  great app!
