Fantastic support
I needed to change, the app I was using to record my reading history was letting me down badly and with nearly 1500 books recorded I had to find a way of transferring my records over into a new app. Alwin at CLZ certainly came up trumps, taking me (a very un-techie silver surfer) through the process step by step. This app really works, is very user friendly and seems to do the job I want it to do. Highly recommended.

Bookworm
My husband is an avid bookworm, and I use CLZ books to catalog every paper or digital book he owns. It's easy to use and it keeps getting better and better with every update. I have been a subscriber for awhile, and I can't imagine being without CLZ Books.

An excellent app
I have used this app for over a decade and it just continues to get better and better. I highly recommend it if you have a library of books to keep track of.

Essential app for book lovers!
I have thousands of books collected over decades and the CLZ Books app helps me keep track of all of them. The CLZ team are also really helpful if I’ve ever had a query or need help with anything.

User-friendly for all age groups
Finding this app at 63 was a blessing. I have an extraordinary library and continue to collect, yet sometimes you find out you already have the book. This app has been helping me keep track of my existing library and when shopping, I pre-scan the book to ensure I don't own it. Thank you.

Read ISBN numbers with OCR!
ty, thank you, Thank You!
This is so useful!
For someone in his late 50’s trying to type on a screen with big thumbs this feature is a HUGE help! From my perspective, a five-second wait is totally fine because it is still massively faster than my thumbs!
It will also have far fewer typing errors than my thumbs!
Did I say THANK YOU?

Five Stars
Super useful for keeping a track of my books. Great to see the active work being done to add new features and improve the app over time too.

Absolutely fantastic!
I have collected books since I was very young so let's say 45 years. I have started and stopped cataloging my collection at least 10 times over the last 15 years. Created access and excel programs only to give up on it due to it being cumbersome. I have tried other apps over the last couple of years only to lose data along with other issues. This time I did trials on different apps and landed on CLZ Books. This was the best thing I could have purchased for my books.

Great App use it for my 3k+ book catalogue
This is a brilliant app we use it to catalogue our 3k+ inventory to make it easier to find. We find it very useful and would recommend it to anyone.

The best organization app for books
This is, by far, the best organization app for my books I've ever used. It pulls resources from every place it's able I've got over 1400 books I've added location labels and sort order. If you're a book lover, the yearly cost is 100% worth it, it's saved me when I had a bookcase collapse!
I've shared this app with family, friends and strangers, I love the online availability, I can create separate lists, sort different ways. I pull up the app while I'm shopping to keep me from buying dups!

Lifesaver
I would just like to thank you for your marvelous Book Collector application. It has been a mainstay that helps me manage my book library for many years now. The flexibility is incredible and accomodates my changes in the way I access and use my books. I am about to finish my MA degree and during my school years I used this application to quickly find books on topics I was doing research papers about. It has been a lifesaver!
Blessings on you for creating and maintaining this application.

Love the customization
Great app for keeping a log of all your books. I love the customization. If you have a movie collection, CLZ also has an app to keep track of that.

A must have for every book lover!
I love this app! Was looking for a way of keeping track of my books and came across CLZ Books app. And couldn't recommend it hard enough! It is very simple to use for both populating the lists and consulting them.

Useful tool
My wife is the library committee chair for our retirement community and we have used CLZ Books as our catalog for our 1600 books. it gives us many useful tools for this activity. We know what we have in our collections so we can check donations for duplicates. We use it when we order or shop for books to ensure that we don't purchase duplicates and waste our limited funds. The fact that we can see our cloud library on all of our devices makes this available anywhere and for both of us.

Book Lover? A Must Have App
CLZ makes it so easy to track my book collection in one tab, my 2024 Read in another tab,2023, etc. Used for 3 years now, will Always use it. Also saves me from duplicate purchases as the scanner will tell me if a book is already in my collection just by scanning the back cover code.

Books
This is a great program and huge value for money. We have about 1,500 books loaded up and when in a book store it’s so easy to check if already in the collection. The program is constantly being improved and requests for help are answered within hours. Outstanding service.
