User Reviews

CLZ Books is widely praised for turning large libraries into organized, searchable catalogs. Reviewers highlight deep customization, barcode scanning with automatic data and covers, and strong duplicate prevention. The app syncs data across iPhone, iPad, and web/desktop, and developers are noted for frequent updates and responsive support. It’s described as easy to use and capable of handling thousands of volumes, including non‑ISBN titles. A few mention the paid model and a minor cover-edit quirk, but overall it’s highly recommended.

Pros

Comprehensive, customizable cataloging with many fields and support for multiple collections and locations.
Fast ISBN/barcode scanning with automatic data and cover art, helping identify owned titles and avoid duplicates.
Strong duplicate prevention and reliable search across the catalog.
Cloud sync and data backup across mobile and web/desktop.

I found the speed at which one could add books was terrific. When I had a formatting error moving my Goodreads collection I simply pointed the camera at my screen where there were 200 barcodes. It just went ping, ping, ping and in a minute it identified most of the books. However quite a few of the books were not found and I came to the conclusion that the isbn database wasn’t as comprehensively full as it appeared. I also couldn’t understand why the “update from core” didn’t work to bring back the cover art without the barcode. It can find the books from title and author so why not provide a selection of covers. Early days but I’m going to pay the subscription because I’ve had $20 worth of fun from it. I just don’t understand why the developers can’t scrape data from the library of congress or the British library to get all the info of every book.

I recently purchased the CLZ Book app and it’s fast becoming another CLZ favorite (I’ve used the Music and Movie apps for many, many years). Hundreds of books are now in a manageable data base with no more physically searching shelves and stacks to see what I have, making it easy to check that I’m not purchasing another copy of a title.
