Of course, you can sync your database between them through our CLZ Cloud solution.

Reviews from customers
FABULOUS ! FABULOUS ! FABULOUS ! It does everything I need, and does it well, and smoothly, and with over 3500 books on my shelves, that’s important. Since then I have switched to their cloud service, CLZ Books. I no longer have to use my memory space. I just log in, make entries, deletions or changes and it’s done. The price is still very reasonable. This is the best book cataloguing service of any I have ever used. They also offer apps or cloud service for collectors of Movies, Music, Comics and Games. This team of developers has done and continues to an outstanding job. I would 100% recommend this to anyone who has a library to keep track of.
So, recently I had a issue with the app. My accounts weren’t syncing to the cloud. So i sent in a email support request at 8:28 am and received a reply at 8:41! I didn’t have to sit for hours worrying. They guided me through what I needed to do and have access on their end to see what the problem is. My issue had been solved at 10:00 am on the same day!!
I cannot thank the customer support agent enough for the fast service and the great guiding!! 100% would recommend this app!
It’s easy to input the information about books and the developers are constantly making changes to make this the best book cataloguing app ever. In the couple of years that I have used this app, I have found the developers are very responsive and responded quickly whenever I had an issue.
If you are looking for an app to develop your library, the CLZ Book App is the answer. I highly recommend this app and give it a 5. If I could, I would give it a 5+++++.
The CLZ Barry scanner enables members to scan the barcodes of books they are willing to loan and email the ISBN numbers directly from the App to our Librarian for logging. Subject to Covid restrictions, we can work directly with any member who has as many books as me, to load the books directly. It is particularly helpful to be able to sort on technique, subject etc as well as author and title.
The software works and the support team are easy to contact and really helpful. Highly recommended!

I tried 3-4 other book cataloging apps before I found CLZ and it’s computer based sister Book Connect, but all those others had their limitations and seeming to be aimed at novels. I needed a serious app to catalogue my very late research and academic library and this was it. I now have over 3000 books catalogued and add every new book before putting it on my shelves. It does not take long to learn how to use this app and customer support is excellent with replies often coming back in minutes. I log all my books with Book Connect on my desktop and easily sync to CLZ on my mobile. Have you ever been in a nook shop and wondered if you had a particular title? You either buy it and get home to find it is a dupe or don’t buy it, get home and kick yourself because you didn’t have it. CLZ prevents this and if it stops you buying one dupe a year it has paid for itself. Shopping online for titles? Check if you have the title with Book Connect on your computer. I love it and have recommended it to loads of my friends.
