App
Librarian recommend.

Great App
I have 2000+ books in my home library. This is a great (and actually fun) way to keep them organized and to see if I have a particular book when someone asks or wants to borrow or so I don’t go buying books that I already have!
Also the app has good support if I run into an issue. I appreciated the emailed back and forth to troubleshoot that just this morning helped me through a glitch — when I was trying to use the wrong (HideMy) email address.

A great app to organize your books, especially if you own hundreds of them. The ISBN scan feature works wonderfully and helps to quickly bring in new books. Highly recommended.

Absolutely love this app
Allows me to keep track of my books, which ones I have read, how I rated them, which location in the house I can find it. The team have made some great improvements such as reading the ISBN number when there is no barcode. Well worth the yearly subscription.

This app is a game changer!
I was assigned the task of cataloging my father’s library, a retired professor with over 3000 books. I have tried to use other apps and struggled. This app is a game changer and a life saver! It’s so easy to scan multiple items and finds titles quickly, it syncs with my computer, and I was able to create a print out to show my father the list with Book cover images! There is no other app like this one! Thank you for creating this!

Powerful inventory app
CLZ Books is a powerful inventory app for serious book collectors, offering customizable cataloging, barcode scanning, and cloud backup. The interface is user-friendly, and customer support from the founder and owner Mr.Alwin is top-notch, though advanced features may require some learning.
Rating: 5/5
Recommended for: Dedicated collectors and libraries.
