CLZ Books reviews from customers
I pretty sure as time goes on I’ll enjoy this as much as the movie app in I have entered my ~2700 DVDs. I would recommend this to anybody with a lot of books who wants to organize their collection. One final note is they have a free backup to the cloud. Enjoy!
My favorite feature is the shake to pick a random book. My son loves it and I love not having to read the same book night after night after night.
