Excellent quality
Wonderful, Sytske - you're a star. And thank you for always following through — I wish other companies did as you do.
There's no other book cataloguing software to compare with the excellent quality and standard of CLZ's. Moreover, the software development team often add enhancements and new additions to the platform (app and web) which are always helpful, and add to the scope of user benefits available: for example, the automated price update for books based on average prices for them in the online marketplace is invaluable for both book buyers and sellers.

NC HB 805 life saver for our school!
NC passed law HB805 that requires schools to post searchable catalogs of library books online and allows parents to block their children from borrowing certain titles, beginning with the 2025-26 school year. This app made the process easy & we were able to log over 25,000 books in 4 days thanks to it & wonderful PTA volunteers!
The app is not perfect but it is economical & easy to use. It saved us TONS of time compared to the protocol that the county suggested we use. HIGHLY recommend if you’ve got lots of books to catalog!

Fantastic support
1st. it's a great database and it's only gotten better over the years with beautiful synchronicity between your phone and their cloud-based service. I love that it tells you the estimated value of some books, not that we collect for that reason. but it's fun.
2, they have fantastic support, because let's just say, hypothetically. some idiot manages to erase his entire database, they are there with a cheerful and clear solution. I'm so grateful. I mean if that ever happened I would be grateful!

Meets just about every need
I’ve been using this app for many years now after trying several others, and it does everything says it will plus more. When you add the backup the team gives you, and the value adding updates that roll out, I really can’t speak highly enough of this app.

This app is fantastic!
I love your applications and really like the format and design. They are very useful. I am so very glad I found it.

Excellent catalog
A very good tool for tracking books. Allows a lot of details to be included, if you care. (For instance, the original title and the translator of a book originally published in another language; or the location of a book in your library.)
Books can be catalogued either by ISBN or by title and author. The ISBN lookup is quite good, and easy to correct or extend.
My wife and I have used it for years, for our 7000-odd book collection, and it’s been a great experience. The developers are also open to suggestions.

Absolutely adore this app
I have a personal library and this was perfect for organizing. Although I don't plan on selling my books it is nice to be able to see the values.

Categorizing my books
It's my first time truly categorizing my books, and I'm loving the app. It's very easy to use, especially the subject matter categories, and the added feature of being able to add books to be bought or ordered is a great touch.
