I have been using this app for at least four years. The use is intuitive, the acquisition system is quick and the database is extremely well-stocked. The cards have an incredible variety of data with high customization. Furthermore, the support in case of need has always been fast and decisive. I highly recommend it for those who want to keep their library in order.

Very happy with this app
I love this app. I have a ton of books now at my fingertips. I don't have to spend hours looking to see if I have a certain book. It works everyone I go to use it.

You guys are the greatest...
I am able to go into any book store and insure I don't buy it a book twice. I am a collector only no resale so it makes my shopping easier.

Great product
First up - really impressed with the rapid response from tech support - it
was much appreciated (how to add multiple authors to a book).
I've been using BookDB, which has been great, but remembering to export to txt and then copy to my phone so that I didn't buy duplicates in the 2nd hand book stores was getting tedious (you may have noticed I have a lot of pre-ISBN books). So the search was on for something that would allow me to maintain a sufficiently comprehensive database on my laptop and sync it to my phone with minimal effort. Your team has delivered.
Mapping fields between BookDB and Book Collector took a bit of trial and error (mark all as Skip Field, then go back and set correctly) and there are a number of notes I'll have to port manually (eg first edition/signed by author/family connection, austerity printing c WW2, condition of binding etc), but all in all, this is a great product - and the cost is extremely reasonable - I've definitely spent more than that on a single book, so the potential saving in avoiding duplicates is real!

I love the program
Actually I am not new to CLZ. Several years ago I had purchased your software for my desktop computer and listed over 700 books I had. I love the program. I since have had several newer computers moved a few times. Donated many books thru the moves and lost my original program on my desktops/laptops.
I was so excited to see you offer an app I can use on my iPhone and reorganize the books I have left which are packed away in boxes currently. So to answer your question I love your app and am excited to get organized once again.

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.

Brilliant app!
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.

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!

Love it!
4500 books and growing my inventory. Works like a charm, easy to use. Almost 2 yeard later, still very satiafied with Book Collector. 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. Here it is 2022 now inventory over 50,000 books.

Keep track of our extensive library
Best app we have found to keep track of our extensive library. Love that you can make personal notes as well.

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.

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.

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.

Great organizer
Great app. Easy to use. Great organizer for all of your books. Excellent customer service.

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!
