CLZ Books reviews from customers

Looks good and works brilliantly!
Extremely happy with this software so far. It was amazingly easy to move my book collection from another database to this database. The only challenge was updating cover art for some of the books, but even that chore was facilitated by CLZ. This app is way better than my previous app; both the phone version and the online version are considerably more sophisticated.

Best Library Catalog App
My wife and I are avid book readers, and we have accumulated over 8,000 books over the years. I wish we had discovered this sooner. We have been to many library book sales, and we came home and realized we already had a copy. Since we found CLZ, we’ve saved ourselves a lot of time and money by checking it to see if we already have what we’re looking at. Thank you so much.

Amazing app
Customer Support actually listens to the users and fix reported bugs. This is the best app to keep organized digital and physical books, easy to use, beautiful interface, fully customizable. I recommend it 100%, I have been using it for over two years and I wouldn’t change it for any other app.

The best!
This is the 3rd library app I've sampled and far and away the best! It scans the isbn number even if there's no barcode. It easily identifies the isbn inside a paragraph of words. This makes the job go so much more smoothly!

LOVE THIS!
Have been hunting for a way to quickly and effectively catalog my home library and CLZ Books is the PERFECT app to do so. I was able to catalog over 250 books in under an hour and it helped me reacquaint myself with old treasures and keep track of what I do and do not have in my collection. I should’ve done this years ago. Thank you!

Honestly, I love it
Between my phone and the web it's so easy to catalog my...very many books and get them straightened out. I may also do it (web+app) for my comics, but that's less of a pressing issue at the moment as the app works perfectly for me right now.

Wish I had found this app sooner
Has really helped me organize my library and keep me from duplicating volumes. Found it easy to add books to the collection.

Amazingly easy to use
I love that i can scan from my computer or my phone and sync then together so I always have a list of my books where ever I go.

Easy to use
A great comprehensive but easy to use database.

Looks good and works brilliantly!
Just add books by isbn works great and if a book hasn't been added you can do that yourself and that's pretty easy too. What I especially like is there are two different coverviews. The only thing that could make it better, for me, is if you could rate the book at the same place where you mark it as being read.
