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.

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.

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.

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.

Excelente aplicación para catalogar tu colección de libros
Excelente aplicación para catalogar tu colección de libros. Valoro el hecho de que permita exportar e importar los datos (otras aplicaciones similares no lo permiten) y de esta manera poder utilizarlos a tu conveniencia.
Excelente servicio de atención al cliente que supongo debe funcionar las 24 horas del día, pues me contestaron una duda por correo al poco rato y era en domingo.
La búsqueda de los libros mediante escaneo de código de barras funciona muy bien.
El único inconveniente, hasta ahora, es el precio. Funciona por suscripción mensual o anual y yo preferiría un pago único, aunque habrá que ver si las actualizaciones periódicas que prometen justifican ese sistema de negocio.
De momento, muy satisfecho.

100% Worth the money
A great app! I had been looking for a book cataloging app and the ones I had seen were fine. I was hesitant to purchase this app when I came across it, thinking that maybe paying $20+ wouldn't be necessary just to have a list of books on my phone, but as I played around with the free version, it really was what I was looking for. I bought this one and the CLZ Movies and I never regretted it! It was 100% worth the money. The customer service is also excellent. They're very courteous and helpful.

Keep track the books I've read
Since I read a lot, I really wanted a way to keep track the books I've read, author, plot, etc. After trying a few apps out, I stumbled upon CLZ Books and I love this app. It does just what I was looking for and more. When I ran into a small glitch, the creators were very responsive and worked with me until it was fixed.

Excellent tool
An excellent tool to keep track of, and categorize my large collection.

Love this app
No more buying a book only to find I already have a copy. I can keep my series together, and fill in missing books.

Great tool
I just downloaded it today and I already love it. Best book cataloguing app I've found. Gives you lots of customization abilities.

Book Collectorz is one amazing application!
I've been using it now for a few years to manage a 1000 book library collection for my quilt guild. What I really love is that the Collectorz team is constantly making improvements to the app that make it easier and faster for the user to manage their collection. The team is responsive and genuinely interested in what their users have to say about the program. The app is simple to use, and very intuitive. You can slice and dice your collection in any way you want to see what you have, and there are a lot of customizable fields if you have specific interests. The connection to "core" is flawless, and simply by putting in the ISBN from the back of a book you get all the information you need in seconds. The price is very reasonable for the value you get from this app.
While I haven't used their other products, I'm sure they are just as refined and useful. Thank you CLZ team, great job!

Top Notch App!
The CLZ Book app is the best app available for keeping track of your book collection. I use this app a lot when I go to Barnes & Noble. I can’t always remember if I have already purchased a book, so I open the CLZ Book app and check my collection. It has saved me several times from making duplicate purchases.
I look through my collection a lot and it is just a great source of reference!

Pleased with this program
I'm very pleased with this program. A few more fields than I need but operates smoothly. Customer response was fast and helpful when I encountered a transition problem in moving to a new tablet.
Highly recommend this app if you have lots of books.

Love this app
Our books had been stored for eleven years until we bought our home and have recently been put in our library downstairs. This really helped us to record which books and series we owned. It saved me from buying double books, as I've done in the past.

Awesome app
This app is awesome, love being able to have all my books listed in one place. Adding them in is super easy to do and there are a lot of nice additional features (cloud syncing, multiple "shelves," etc). I think this is well worth the cost! Support also responds very quickly!

The best
I've been using this app for years and it is the best app for its purpose.
