Or... use them both,
as perfect companions!
Both CLZ Books Mobile and CLZ Books Web can be used on their own, as a stand-alone solution. But these tools really come to life when used together, as they are great companions. While away from your computer use CLZ Books Mobile on your phone, then use CLZ Books Web at home, to work on your database on a big screen, with a real keyboard. Of course, you can sync your database between them through our CLZ Cloud solution.

The best I tried
CLZ Books is the best of several I tried. I have a huge project of entering 60 boxes of books and then offering them for sale. Exporting data to a format I can share with buyers is well done.

Excellent app
I had used Delicious Library back in the day but this blows that completely away. The functionality is great and the appearance is uncluttered but complete. Very easy to use and responsive developers!

Fantastic product
I am an avid reader. I needed a way to track what I’ve read, find out what else an author has written, and make a list to go shopping. I also needed an easy way to add books. This app does it all. It has many features and kind, efficient support when needed.

Essential
This is such an essential app for anyone with an extensive library or for those who like to keep their collection organized and accessible. Also a great tool to keep a record of the books you own in the event of a worst case scenario. Easy to use and extensive with a lot of features. Love it!

Very easy to use
I access my inventory constantly because I can never remember if I have bought a bought a book yet or only wanted to buy a book. very, very much worth the money!

Perfect app for my books!
I love the different ways I can organize my books and see the whole collection. I peruse used book stores quite often and this is a useful tool to make sure I don't buy a book I already have. Embarrased to say I have done that a few times...

Astonishingly good
CLZ Books is the most wonderful piece of software, enabling me to keep track of my library. Loading new books is made easy through use of ISBN recognition, and the editing and display options are easy to operate and comprehensive. The owners and software engineers must be congratulated on producing a really astonishingly good product.

Great product
I installed this app a week ago and have already entered hundreds of books. This product is easy to learn and easy to use. It is just what you need to track your books. The developer has already contacted me in case I had questions. An amazing product and company.

This app is wonderful!
This is an amazing app. I was looking for a way to catalog all my books as I have multiple ways I read them. Kindle, Audible, Chirp, and physical books. I am now able to look at 1 app to verify if I have read a particular book and where the book is located.

Best Library App
I have been using CLZ Books the over a year and after trying so many other apps I can honestly said this is the best app out there.
I can add my own information and upload my own cover, so many fields to add details. It synchronizes online immediately and I can share my collection with others.
Customer support is quick and efficient, always open to suggestions and new features ideas. I’m very happy with this app.

App consigliatissima
Ottima applicazione. Stavo cercando una che fosse disponibile su Android e IOS, oltre che web (arrivando da una solo Android, comunque ottima). Ho provato l' import della base dati ed è filato tutto liscio. La ricerca delle cover dei libri è efficace e veloce.

I'm quite impressed with CLZ books
It is well thought out and easy to use. Having entered over a thousand books thus far, the ISBN and author/title searches generally work very well. Data can be simply edited as needed. The ability to search and also add tags to books is very handy. The cloud syncing makes it easy to move between an Android phone and an iPad. I've tried a number of times to organize our books with other S/W, but this is definitely the best I've used.

Complete database for books
Extremely versatile and complete database for books. I've tried numerous others but none could match the quality of CLZ Books.

Simple and quick
Simple and quick to add books to my collection. Now I can track what books are where. I will also quit purchasing the same book twice. I can also see which edition/version I have. I can include as much or as little information as I like.
