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.

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.

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.

Works like a charm
4500 books and growing my inventory. Works like a charm, easy to use. Almost 2 years later, still very satisfied with Book Collector. Now managing over 25,000 books via using both desktop and Android versions. Work well together, application is updated regularly. Support is great, have issues? They will respond pretty quickly and help you with the problem. Staff responds well to suggestions and questions and have helped me quite often.
Here it is 2022 now inventory over 50,000 books. Love it!

The Best
The best such app I’ve found and I’ve tried many. The customer service is top notch and responds quickly. The upgrades are regular and useful. The customizations are tremendously helpful. Love this suite of apps!

Does the job
I’ve tried a few cataloguing apps and this combines the best of all of them. Very customisable with fast scanning via your phone’s camera.
When contacted the customer support is super fast and personal.

Great program and service
I was using this app to catalog the 4000 books in my collection. After about 1000 bucks I upgraded to an iPhone 14. It turns out that the camera on the iPhone 14 will not properly scan the barcode. I contacted the developer and they immediately got back to me. They kept me informed of the progress of the upgrade. They have subsequently fixed the problem and the app works fine now.
The app itself is particularly useful if you have books published after 1967 - you can just scan the ISBN code. You have to manually enter the name of pre-ISBN books, but usually the database that the app is connected to will have some of the information. You can then incorporate that information into your collection database.
