Recently I decided to sell some of my business books, (I’ve retired), and the new pricing feature has been a huge help to determine which to keep, donate or sell. I also track books I loan, which ones I’ve read, where I got them, and where I put them (I have a lot of bookcases.)
In general I’m not an app fan, but this is the exception to that rule. The team are super friendly, send me quick personal emails when I have questions, have implemented suggestions, and continue to innovate. I couldn’t be happier with it.
