Given this review: "I was in love with this app. That is until I had over 400 books saved in it and one day POOF all of them were gone. I hadn't reset the app or anything they just disappeared. Here i am thinking ill have a resource to refer to to save from dupes and whatnot but no it was just a waste of my time." Would you recommend this app to a friend? Not at all, No, Maybe, Yes, or Definitely?
