I've tried several alternatives, but none of them compare to the CLZ Books app. I also use the CLZ DVD catalogue app, which is equally brilliant. They're easy to use, intuitive and have a cloud backup system that's very reassure. Thank you. — Somayeh Moballeghi on July 17, 2022

Your library in your pocket
User friendly app to keep track of books, music, and more. Know what's in your media library and avoid duplicate purchases. You can even create a wish list for items to add to your library. Works on a desktop computer as well as a smart phone. — CB Youngblood on CLZ Books

Fantastic App!
The app has been fantastic! As my collection grows it’s hard to remember exactly what titles are in it sometimes, your app fixes that issue for me! — sjruss86 (Canada) on CLZ Books

Now managing over 25,000 books via using both desktop and Android versions. Work well together, application is updated regularly. Support is great, have issues? They will respond pretty quickly and help you with the problem. Staff responds well to suggestions and questions and have helped me quite often.

Keep track of our extensive library

Keeps me sane
I have had this app since 2018. This is the one app that has kept me sane. It does everything I need around books. All the memory is stored on the app so I do not have to worry about memory space. I have almost 800 books and this app has made it easier for me to know what I have, keep track of where the book is ( I am able to include notes on a book if I have to lend it out to friends or family) and adding new books is easy. I highly recommend this app to anyone who has or is planning to build their home library. — Quaydiquay (Canada) on CLZ Books

Love the CLZ series of apps
I use this one for my books and the CLZ Games for my modern & retro games. I am happy to pay for premium of both just because the price is so reasonable and the apps are so good. Being able to add items by scanning the barcode with the camera on your phone is just awesome. Love it. — Shane Hurley (Ireland) on CLZ Books

Couldn’t Live Without
I’ve used CLZ for years and totally depend on it to maintain my over 2,200 book list. Originally I imported my, considerably smaller list, from another book collector app and found that CLZ far surpassed the other app. The many available fields make it easy to track whatever is important to you. Anytime I’ve had a question support has replied to my query quickly. Support is absolutely awesome. — GrandPuppy4 (USA) on CLZ Books

Perfect to keep track of everything
Downloaded the trial and started adding books, upgraded to yearly subscription within 1/2 hour! Most of my library is packed away for a bigger house so this app is perfect to keep track of everything I have and don't have as I keep going with my collection. The book Nerd and organiser in me LOVES this app! — Lozzerella (USA) on CLZ Books

Keep up the good work guys!
This app takes a bit if getting used to at first, but the catalogue is extensive, and most bar codes and isbn numbers can be used to autofill a good chuck of a collection. — JazzTripp on CLZ Books

Was hesistant due to cost, totally worth it

Adding books is a breeze
Great app! Easy to use, clearly and cleanly laid out. Adding books is a breeze - just scan the barcode. I really like that my collection information syncs with and is backed up in the cloud. Customer service, on the rare occasions it is needed, is just excellent - I had a question to which the response was (1) polite, (2) really fast, and (3) really well and clearly explained. I am very, very pleased with this app and company. — Sean Alexander on CLZ Books

Excellent App
We have a large collection of books. This app allows us to catalogue our collection and in doing so provides a real time view of books on hand. It also serves as a valuable resource to provide guidance for insurance coverage and the family with what is available to be borrowed. — greenwom02 (Australia) on CLZ Books

Simple and easy
I had another app that I was using to store my collections of books that I own to help me remember but it never added titles and that app disappeared from the App Store. I like this app because I get to just scan my books into it and it sorts it out in order for me and I don’t have to put any guesses whether I own a book or not when I’m out or online shopping I just check this app. Also way cheaper then other organizations apps. — Hhggttddkkffttbh (New Zealand) on CLZ Books
