Latest software updates

Alwin and Team,
I've been using Book Collector for a number of years now and decided it was about time that I express my appreciation to you for not only developing the best "book software" product on the market, but also, for your continuing updates and frequent communications. Book Collector has more than met my needs for the 2,000+ books I've logged. So again, a well-deserved thank you to you and your staff.
P.S. I just recently purchased Movie Collector to log all of my DVDs and CDs. I'm very satisfied.

Thanks!
Just wanted to say I appreciate Alwin's emails explaining what's new in each software release, particularly the iOS apps, where new features are often hard to find. And, of course, thanks to everyone for writing such great software! — Mark McGarry on CLZ Books

Brilliant
This isn't a question just a "well done". The clarity on the new screen text/images is fantastic. It has given the application such a clear and modern look. Brilliant.
I have used Book Collector for 15 years and watched it develop. I wouldn’t be without it. — Pat Roberts (United Kingdom) on Book Collector

Thanks!
I wanted to thank you for all your help and getting me out of this book collector nightmare. I followed all your directions and it is now working. I have zapped in 16 books today and every thing seems to be working fine.
You have been so helpful to me with all of this. I would never have got this working with out you. I really appreciate all your time and effort. — Marie Gray on Book Collector

Love this app!!
After years using only the computer version I recently finally started really that together with the app. Works really great cause of the good working synchronize option. And I'm very happy with being able to search for almost anything in the database. — Marlies Roeland on CLZ Books

Greatest
I love this app. It is exactly what I need to catalogue my books. It’s very flexible and easy to use but provides lots of options for sorting and placing in folders. It also has multiple views of your information. I was really happy to have the free copy to check it out before buying the full version. It does everything I want. I have thousands of books so having the scanner work well is huge. I also like having it on multiple devices. The sync works well. I have been looking for an app like this for years. Can’t say enough good things. — Gmablake on CLZ Books

Love your program
I love your program and recommend it to all my friends.
Some of my friends who are using your product don't just collect books. One collects comic books and another collects music. Your product is great for all collectors. — Bill Iversen (USA) on Book Collector

Love this
In the past I have bought multiple copies of books and haven't realized it. However, this app has stopped me from doing so and it's a great way to keep everything sorted. — J C on CLZ Books

Gorgeous app
Just downloaded this gorgeous app and have spent the day having a lot of fun figuring it all out and adding some of my books, which has proven wonderfully easy. This is one of the few apps I’ve ever felt I would happily pay for even though the cost is just a TAD bit pricey.
THANK YOU for designing such a beauty of an app. It’s a pleasure to use... and even better, it’s a pleasure to look at! I’m in love with your creation! I just got my first UPDATE notice already.... which means you guys are busily working away at making CLZ Books even BETTER than better! I’m happy about that! — Nancy on CLZ Books
