Thanks for creating this way back when. I'm more than happy to have a subscription. Thanks for your improvements and making this the best option to catalogue my books

Best app ever!!
CLZ Books is my go to app for tracking my book libraries. I rely on it whenever I purchase new books or audiobooks to avoid duplicating purchases. I recommend the app to all my friends.
The customer support function is also outstanding. I recently had an issue and contacted customer support for help. They responded quickly and helped solve my issue. Having such customer support makes the app that much better.

So easy
Scanning books is so easy! I was using a different app to track the books i own, but was having problems with it properly tracking them. This app is so easy to add and navigate!

Great organizational capabilities
I've been using the comic app for some time and love it, great organizational capabilities, and I just learned you have a book app and it has everything I need.
Love it!
Love it!

Amazing
If you are looking to catalog your book collection then look no further. App has lots of hidden gems and I’m so glad I found it and now using it. You won’t regret it!

Love Bookcollector!
You guys are SO AWSOME!! I LOVE both the app and online, though I am using the app most of the time now. It is wonderful to be able to scan in new boioks and and notes, edit, wherever I am! I am happy to support!
I have been a very satisfied customer for many years. It is so useful and fun! I never fall behind in keeping my new book purchases entered because with the phone app I can do it in 30 seconds or less!
I LOVE being able to scroll through my book library by viewing the covers! While reading a book, I can add personal notes for future reference and to make the book more searchable for me later ( like a note as to who recommended the book to me)
AND whenever I am having a conversation and want to tell someone about a book that is relevant, I quickly do a search of my collection ( on the app), even if I can’t remember the exact title or author, usually a key word is enough to find it.
Would you believe that my personal library is over 4,500 books? I would be overwhelmed without the Bookcollector products. It is so fun to have the info available right at my fingertips on my cellphone! And to know it is safely stored on the cloud. But even if you only have 100 books (or comics or music), I highly recommend CollectorZ. Truly a great value from a wonderful thoughtful supportive company with years of expert development!

Couldn't be happier
Just wanted to drop by and let you know how pleased I've been with Book Connect and CLZ Books. I've been a Collectorz customer for several years, and couldn't be happier.
My collection has grown to 2125 books, and I don't know how I could manage without Collector.com software. I can't tell you how much money I have saved in a bookstore, being able to check whether I've already owned a book I was about to buy!

There is no easier way than to use this app
I have been using the CLZ apps since they came out in 2019, but I have been using the desktop program since 2002! If you want to catalog your books, there's no easier way than to use this app. It allows you to enter an ISBN and finds the book details for you to add to your collection. You can add further details, etc. You can also assign it as "In Collection", "Wishlist", "On Order", etc. When I go to a bookshop, I can see my wishlist! If you have the desktop app, you can sync back and forth!

LOVE your product
I LOVE, LOVE your product and have almost 600 books in my collection. I read almost every day and use it often. I also have it on my phone and tablet. What a great resource it is.

Great!
Have had this app for years. Works great!

Lifesaver
Nerding out at home. Having some trouble with my older books not matching up with anything in the database, but it's good. I love having things stored in my phone. So much better than my book of lists.
Update: this has been a lifesaver for when I forgot that I loaned out some books. I check them out in a folder to specific people. Worth every penny!

Very helpful customer support
I had a problem, all my books disappeared, all 1949 of them (well except for 7 of them). After an email to customer support in less time than I expected, a reply from a nice person named Alwin told me exactly what I had done & how to get those books back. Hey presto & there they were, just like magic...whew.
So very helpful customer support, thank you Alain.

Happy!
An amazing app, powerful, affordable, and yet, user friendly. You can insert books automatically via barcode with a phone, and if the book is older, without a barcode, the app proposes manual insertion. I'm really happy!

Brilliant
Easy to set up and use and as I have it on my phone it's great for lookups in bookshops to make sure I don't duplicate purchases. The location field is also great as it lets me find my books easily across the 5 bookcases in my home.

Library
Great way to keep track of my written library.
February 17, 2023
I have used this app for the past 4 years as I collect manga, light novels, comics, and books. This app has been the best way for me to keep my collection organized and help me keep track of what I own. I especially like that I am able to manually add in any obscure titles that I may find into the database. I would highly recommend this app for anyone wanting to keep track of their book collection.
February 06, 2023
Useful software
I'm downsizing my collection of dictionaries and language books, and I have found Collectorz Books useful for recording what I am getting rid of. I have created a separate collection called "Deleted books", which are those I don't want any more, whether sold or not. I move books to this collection when I make the decision to get rid of them, and alter the collection status to "for sale". Once sold the status is changed to "sold". That way I can track them instead of wondering whether I have sold something or not! Users who want more detail could add fields such as "date sold" or how much it sold for.

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!

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!

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.

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.

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.
