== What our users say ==
"A fantastically nice book library app that I am incredibly happy with, you really get an overview of the things that need to be sorted out, for a good overview, easy to use and everything works seamlessly. Strongly recommend."
Emmanate (Norway)
"The best I have found. I have over 1200 books and have used a number of book cataloging apps over the years. CLZ Books does the job of keeping track of my library and gets syncing right. Most importantly (speaking as a software developer) they keep improving the app. It’s tough to make a business of niche software products. These folks have apparently figured out how to make a go of it and they keep improving. Kudos to them!"
