This is the very best book catalog app for Android available. I've tried every single one available in the Google Play Store  and most in the Amazon app store. It isn't perfect and I look forward to improvements but it's still quite good. It's easy and fast to use and provides a decent overview of books I've entered. I'm wishing for a few additional variable points to enter info I consider important. In the meantime  Book Catalogue is the best available in its category.
