Latest software updates

I would like to congratulate you on recent changes. The new design for the Book Connect is excellent, it is cleaner and crisper, plus it is faster to use. That is always a plus. Additionally, the changes to searching in the Core are beneficial as well, much faster, especially the new integrated search blank (author and title together), plus the way we can now see more information about each book in the Core. That is a big help in selecting a good volume out of many. Bravo! — Debbie Cox on January 10, 2018

Love this app!!
After years using only the computer version I recently finally started really that together with the app. Works really great cause of the good working synchronize option. And I'm very happy with being able to search for almost anything in the database. — Marlies Roeland on CLZ Books

Greatest
I love this app. It is exactly what I need to catalogue my books. It’s very flexible and easy to use but provides lots of options for sorting and placing in folders. It also has multiple views of your information. I was really happy to have the free copy to check it out before buying the full version. It does everything I want. I have thousands of books so having the scanner work well is huge. I also like having it on multiple devices. The sync works well. I have been looking for an app like this for years. Can’t say enough good things. — Gmablake on CLZ Books

Love your program
I love your program and recommend it to all my friends.
Some of my friends who are using your product don't just collect books. One collects comic books and another collects music. Your product is great for all collectors. — Bill Iversen (USA) on Book Collector

Love this
In the past I have bought multiple copies of books and haven't realized it. However, this app has stopped me from doing so and it's a great way to keep everything sorted. — J C on CLZ Books

Gorgeous app
Just downloaded this gorgeous app and have spent the day having a lot of fun figuring it all out and adding some of my books, which has proven wonderfully easy. This is one of the few apps I’ve ever felt I would happily pay for even though the cost is just a TAD bit pricey.
THANK YOU for designing such a beauty of an app. It’s a pleasure to use... and even better, it’s a pleasure to look at! I’m in love with your creation! I just got my first UPDATE notice already.... which means you guys are busily working away at making CLZ Books even BETTER than better! I’m happy about that! — Nancy on CLZ Books

A big THANK YOU
I just wanted to send a big THANK YOU for making the app I’ve always needed in my life! :D I’m such a control freak when it comes to my books and this app has made it both helpful and fun to get a good overview of all my books! (There’s a LOT of books...)
So thank you, keep up the great work and happy Friday! :) — Trine on CLZ Books
