Longtime user

I have used Collectorz since it was desktop only and I love it! Excellent way for me to see all of my books. It definitely keeps me from accidentally buying a book I already have! Great product, excellent company.

CLZ Books

One of the best apps in the field. The price also reasonable. Convenient and user friendly.

Absolutely perfect!

Purchased this app at my husband’s suggestion (he uses his for his DVDs, books, and CDs…we’re old school!)…I am in the process of cataloging my hundreds of cookbooks. Easy to use. A valuable tool to finally organize my collection! Highly recommend this product to any collector.

This app more than pays for itself!

There are a couple of genres of books that I’m apt to buy when I come across them. More times then I would like to admit, I have found the book I was thinking about buying is already in my collection. It’s super convenient to add new books and to record where I stored them. I can also record other facts about it that are sometimes helpful. An excellent app! So easy to use!!
