Latest software updates
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.

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.

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!

Book library
I recommend Collectorz to all the collectors I know and my father-in-law loves it for keeping track of his extensive book library.

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.

Was hesistant due to cost, totally worth it
Very impressive database. It's been able to recognize various pre barcode books with no problem based on isbn.

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.

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

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

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!
