This App has awesome support!

I purchased the CLZ Book App a few months ago. I have to say that they helped me upload my collection when I was having problems with the CSV file. Their support has been so wonderful. Just recently the App started crashing on me on my phone when I tried to edit a new entry to place it in a collection. I contacted support and they got back to me before the day was out. He asked me some questions and gave me a few things to try. Before I could even try those suggestions out, I got an email saying that they had found the bug and were submitting their solution to Apple. It was so nice to know that there was a real person on the other side of the App and not an automated message. I love this app, for it’s ease of entry and also for the support. I bought the full version and am very happy with it.

Thank you CLZ!

I am amending my review to reflect the wonderful customer service I have received, as well as the functionality of the app. Of all the apps I tried to catalog my antique book collection, CLZ Books is my favorite. I like all the various data you can input, including reading date and price. My collection is from well before ISBN numbers (being published prior to 1900), so ease of manually inputting all of the data I want is important to me. I did try out scanning on one current book and it worked very well, but I haven't explored that side extensively. I am excited to unpack the rest of my collection and get them entered into CLZ Books!

Review II
I have used this app for several years after many other trials that did not work well and I must say I have had the best customer service any time I have a suggestion or find an issue. As a book collector I depend on it to show me my existing collection as well as any library books I may read, when I am out at the bookstore. The new ability to separate into collections is great! I have books in boxes and now I don’t have to view them when looking at my collection list. Keep up the good work!

I love this app. Could it improve? Yes, but overall awesomeness is present.
