Spot on!
The tech response and program is spot on! — Kathy Stromer on CLZ Books

Great app, easy to use, wonderful support
I’m using this app to catalogue my collection of over 1,000 cookbooks. Scanning the ISBN numbers with my iPhone has made this task much less daunting. I can also customize my results to my way of liking. Support is immediate and knowledgeable. Highly recommend this app! — Nrupup on CLZ Books

This App has awesome support!
I purchased the CLZ Book App a few months ago. I have to say that they helped me upload my collection when I was having problems with the CSV file. Their support has been so wonderful. Just recently the App started crashing on me on my phone when I tried to edit a new entry to place it in a collection. I contacted support and they got back to me before the day was out. He asked me some questions and gave me a few things to try. Before I could even try those suggestions out, I got an email saying that they had found the bug and were submitting their solution to Apple. It was so nice to know that there was a real person on the other side of the App and not an automated message. I love this app, for it’s ease of entry and also for the support. I bought the full version and am very happy with it. — Pippin414 on CLZ Books

Nothing’s perfect, but some things are close
I tried three other apps before I settled on this one for cataloguing my fairly extensive book collection (around 3k volumes). The deciding factors were: ease of use, particularly in finding relevant catalogue records from ISBN with or without barcode; use on both iPhone and iPad (synchronised, obviously); some potential for additional bespoke data items I might want to add; and good customer service from the developers. This is the app that ticked all those boxes.

The interface is good, easy to use, and I’ve added a lot of records very quickly, at the shelf with my iPhone. They often need editing (different editions, covers etc), but this is done easily and effectively. Synchronisation is excellent, and indeed you can access your database through the web interface, and there are Windows/Mac versions (at a price). I haven’t fully explored the additional data fields available, but they seem good. And as well as seeing a number of reviews which mention the excellent customer service, I’ve experienced it myself, with very full engagement from the developer with the issues I’ve raised - none of which have been major.

Nothing is perfect, and there are things that could be improved. You can’t do multiple item edits on the iOS version (you can on the desktop versions), eg to overwrite all “genre” entries across a number of records. There are some slightly awkward user interface issues in inputting records (issues the developer has agreed to consider). But I have confidence that the app will improve - it’s regularly updated - and it’s building on a very solid basis. So overall - I’m very happy. And I don’t say that about many software products! — Ben0779 on CLZ Books

Great app and excellent customer service
I have installed this app because it was the only one where I could upload my existing data; it has been a wonderful discovery, user friendly and professional at the same time. Highly recommend. Every time I ask for advice and help the customer support answer immediately and answers my questions. Good job! — MayRoses on CLZ Books

Wonderful app
Like all of the catalog tools, they offer this app is amazing. I have over 1,500 physical & digital books plus over 2,000 magazines and the app lets me track them with super fast reports and plenty of group by options. A must buy if you want to avoid buying duplicates or want to know what you have for insurance purposes or the pure joy of it. Collectorz has been keeping my collections organized for a decade now. — Yodaman70 on CLZ Books

Nette database voor boeken
Gebruik deze app zodat ik weet welke boeken ik al heb digitale en echte boeken, makkelijk invoeren met scannen van streepjescode en ook handig handmatig in te voeren, bij vragen word er snel geantwoord en hulp aangeboden, top! — pauline 1961 on CLZ Books

A great app with brilliant support
This is without doubt my favourite app. It’s visually intuitive, easy to use and enables me to sync my library across multiple devices. The support is also exceptional - I had a problem after downloading a software update which Alwin responded to promptly and efficiently. He told me the day and time the problem would be solved and it was. I’ve always recommended this app to friends and I’ll continue to do so. — Dr-PH on CLZ Books

Tracking for my favourite authors and series
Great for tracking which books, authors, series titles you’re missing in your collection. Barcode scanning allows for things to be added quickly. All the CLZ mobile apps are great for this. — riders4ever on CLZ Books
