Tip: use CLZ Books together with the Book Connect web-based software

Our Book Connect web-based software is a great companion to the CLZ Books mobile app, as it lets you work on your collection on your computer. That is, on a big screen, with a real keyboard and mouse.

Of course, you can easily sync your collection data between them through our CLZ Cloud.

Great app

Simple to use and excellent updatable database!
Uploaded virtually my ENTIRE personal library (1300 books and counting) over course of a few weekend evenings. The few glitches encountered were entirely self-inflicted. Great personal interaction with app experts (Alwin, Sytske, and team) as needed. Awesome app! — Danny Garcia on CLZ Books

High-fives to the whole development team
I have been using your app for a number of years. I just wanted to reach out and let you know how much I look forward to your updates. Every single update you've made to this has been amazing. 9 times out of 10, it was something I didn't even realize was missing, and now use with every new book I add.
Great work - huge thanks and high-fives to the whole development team. Keep it up! — graycloak (USA) on CLZ Books

Just what I needed
App turned out to be just what I needed to keep track of my massive (and growing) book collection. Had way more of my titles automatically in the system than I thought going in (figured I'd have to add a lot of them manually but actually really smooth). Sytske helped me with a little issue but otherwise lovely app and people behind it. — Mecho Gecko on CLZ Books

The best book cataloguing app available
By far the best book cataloguing app available, I've tried several and clz blows them all out of the water. If they had a lifetime membership subscription I'd even take it because it's so good. Customer service is extremely helpful if you have any questions as well. Couldn't recommend it more. — N S on CLZ Books

Love them all
Easy to use and I can create separate data files for each person in the family. I have CLZ for books, comic books, and movies love them all they do a lot more than I will ever use but I got them because they sync and backup to the cloud and after losing thousands of records from the freeby apps, never losing my records again from changing phones is the greatest. — Jim Payne (USA) on CLZ Books

Helpful app
Looks good and works brilliantly! Just add books by isbn works great and if a book hasn't been added you can do that yourself and that's pretty easy too. What I especially like is there are two different coverviews. Option one; everything is boxed in and looks very near, the other option has the same height for every book, so wider books will be displayed large as well. — Douwe Drijfhout on CLZ Books
