It's a very basic app and does what you need it to in terms of scanning and organizing large amounts fast. I'm taking away 2 stars because of somehow unknowingly being on a trial, when I had already set it for the monthly subscription. Guess who had a surprise charge for the yearly subscription? Not impressed. Doubting im even going to use this app for a year and now I've paid more than it's worth.. so double check when you start using this app

CLZ is the best way to catalog your books at home, and carry them with you on your phone. There many programs out there to keep track of your library, none of them are as easy or clear or complete as CLZ. The amount of information you can store, including cover image, is tremendous. And the storage is huge. I have 6K books in my file. It's a simple, intuitive program to master. And when you're in the bookstore you won't have to guess which titles you already own. It's simply the best.

I love how easy it is to look up whether or not a book is in our home library! Initially, I got the app to track storage locations when everything would be in storage but accessible for a year. Yes, there are simpler/cheaper booklist options out there, but this one lets me have all the details of a library catalog. We have over 1500 books, and this definitely helps prevent duplicates!
