CLZ USERS ABOUT CLZ BOOKS:
"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!"
LEK2 (USA)
"This is THE ONE. I have a lot of books, and I have been looking for a very long time for a great library cataloging app. A friend of mine showed me this one and… Yes. This is it. So easy to use, so easy to add books and create collections, add covers, anything you want to do. I love it I love it I love it.
Also Customer Service is absolutely terrific."
OolooKitty
"I first gave 5 stars to this in 2018. In 2024, it still delights. If I could give more I still would now. Such a useful book database app which is constantly being improved.
I have had occasion to contact them a couple of times and they have always been courteous, friendly and immediately helpful. I can thoroughly recommend."

CLZ Books 10.7.1 Update
Faster down-syncing from CLZ Cloud:* Syncing now down-syncs the *data* first, while queuing the *image* downloads. This makes the data sync super fast.
* Downloading the images is much quicker too, especially on fast connections, as it downloads multiple images at the same time.
* As soon as the data download has completed, you can close the Sync screen and start using the app. The image downloads will continue at the bottom of the main screen, prioritising images that are "in view".
