Your reporting and printing functions and features are beautifully designed. So utterly intuitive and written by someone with lots of experience technically and with practical user experience and knowledge too. Certainly a great combination!
I am looking forward to showing and getting others interested in your application.

A verry satisfied customer
I'm a user of bookcollector since its start. I didn't pay attention to the required update and I ran into a lot of troubles, which I created myself, on Sunday last. I contacted the help desk and I got a response in the same hour I posted my help call. This was the start of a lot of mails and eventually my booklist I feared to have lost, reappeared on my iPad and PC. I'm verry happy, not only with the product but even more with the kindly support, given with great patience for a hard learner... A trustworthy company. I'll have to learn how to use the extra feature but I'm sure that help is always available! — Remy Vanden Berghe (Belgium) on Book Collector

Handy and easy
A perfect tool to have oversight of my many books; especially while I have both printed, e- and audiobooks. — Vanudele on CLZ Books

A Very Good App!
An absolute 5 stars!!!!! Frankly this is a very good app for me because I’m a heavy reader and I use the app to put all my books info like price of the book, where I bought it and when did I read it etc....It’s very easy to use. It allows me to enter the info either manually or by scanning, it has a huge database of books (have to be online to get access). For those books I can't find it allows me to add to the database. If you are a book collector or if you are a reader just can't help writing down some notes for the book you've read (like me) then this is the app for you! I highly recommend it. Keep up the good works!! — Scherzo232 on CLZ Books

The best cloud database I’ve found!
For years I’ve tried several systems to manage my book collection database. I’ve created Excel & Access spreadsheets & databases nothing seem to fit the bill. Spreadsheets although functional lack of visual component that is important to manage your collection. Collectorz is the best app which allows me to store my database in the cloud and access it from all my devices! — applenicolo on CLZ Books

I LOVE CLZ!
Wonderful!!! All my books are now in my CLZ app!!! Alwin, I cannot thank you enough. I am so grateful for all your help, all your patience. I could not have done this correctly without you. You made it so easy. You are a book angel! You and CLZ gave me the tools and the aid to accomplish that rescue mission. I am so happy. I will sing praises of CLZ to all my bookish friends!
It is poetry in motion! All my titles are tumbling down into my app! Marvelous! It took me weeks to enter all these books last year. I LOVE CLZ! — Mary Erler on CLZ Books

Love this application
Bought the permanent app about a day after 'playing' with the startup offer. Gradually going through the some 1500 (?) books I have and cataloguing them. Good work for the winter if it is particualarly snowy this year:) — Rick Jones (USA) on Book Collector

The barcode scanner is excellent
The perfect companion to the main PC version. The ability to add books direct from the app using the barcode scanner is excellent. I've been using the Collectorz apps for years and will continue to do so. — Andy Turner on CLZ Books
