It's like magic!

I think the cover scanner is absolutely incredible; it's like magic! How does that ever work; how is that even possible to scan an image or even partial image, parse through the database, and return the exact result in like "A" second!? Blows my mind everytime I use that feature!

Home Library

I have been thinking about cataloguing my books for years but the daunting task always stopped me from doing so. I then came across CLZ and thought I would give it a try. I was very impressed at the ease at which I could enter books and the speed using ISBN bar code. I also found the App flexible to be able to add obscure books and very old books.
Very pleased and I even enjoyed the experience of adding books. It suited my requirements and much more.

Wonderful tool

Just a note to say thanks very much for your wonderful tool. I was able to use it to easily and quickly catalog my mother's collection of scholarly scandinavian books. The cloud feature is wonderful, as I am now able to share the library with universities who are interesed in receiving the books. I had originally planned to use a spreadsheet and photos, uploading it to dropbox, but this is so much better.
Thank you so very much.

So easy to use!

I helping a friend move & she is reducing her considerable library for the first time in 20 years. Over 500 books scanned by CLZ and easily tagged for keep, resell, & donation. So easy to use! The CLZ app makes all of that possible. I like the desktop version for modifying or editing any folders or books but quick fixes.

Perfect Library Organizer

For those like me who are obsessed with books (children’s books in my case), and have a copious amount, this is perfect for keeping track of what I have so I can stop buying doubles!

Great App

I have 2000+ books in my home library. This is a great (and actually fun) way to keep them organized and to see if I have a particular book when someone asks or wants to borrow or so I don’t go buying books that I already have!
Also the app has good support if I run into an issue. I appreciated the emailed back and forth to troubleshoot that just this morning helped me through a glitch — when I was trying to use the wrong (HideMy) email address.

Excellent

A great app to organize your books, especially if you own hundreds of them. The ISBN scan feature works wonderfully and helps to quickly bring in new books. Highly recommended.

Absolutely love this app

Allows me to keep track of my books, which ones I have read, how I rated them, which location in the house I can find it. The team have made some great improvements such as reading the ISBN number when there is no barcode. Well worth the yearly subscription.
