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."
Mark Maffey

"This is the best book cataloguing application and the mobile version is a god send with the ability to scan ISBN bar code."
Michael Bartlett (USA)

Ratings and reviews

I love that I can inventory all my books in one location and sync them to the cloud! Easy to use and add all my books quickly, especially if they have an ISBN. Some of my really old books take longer to add since they don't have an ISBN to type in but it still doesn't take long to add them to the book database. Hopefully, when I am adding them it may help other people to find those books in the future. Of course the ones I'm adding are really really old and probably aren't many of them left.

It's not perfect, but it's as close as it gets for what this app does. There is really no good alternative, and it is very robust and moderately user friendly. My one big critisism is I wish it was easier to scan books out of my inventory in a timely fashion or if that feature exists I wish I could find it.

Easily one of the best apps I've ever spent money on. I'm an avid book collector, and this makes tracking my collection so easy and customizable. If I had one constructive criticism it would be this: When sorting books it needs to ignore "The" when the title starts with it. It would save me so much editing time if it did this.

What's new

Several smaller improvements:
* Statistics: nicer looking Recent Additions and Most Valuable top lists
* New folder options for all Date fields, that let you group your collectibles by Day or Month, e.g. by Purchase Month, or Added Day.
* Redesigned Sort Order screen with clearer options for choosing between ascending and descending sorting (now called “A to Z” / “Z to A” and “Oldest First” / “Newest First”)
