Here's what customers have said about CLZ Books:

Proper plots

"My manga and books now have proper plots. No more relying on core."

July 03, 2015

Extremely useful and very easy to use

"This is one of the most useful apps around. I quite often forget which books I have read - especially when out looking in the bookstore - no more! A quick search on my iPhone and I can find if I have already bought the book that takes my interest. The new Cloud Sync makes synchronisation between my iDevices and my PC effortless.
Definitely recommend."

Awesome product!

"Great library software! I can now keep track of my books, what I have, where they are and even a short description of the plot. Amazing!"

"In your house contents insurance policy individual books are not replaced individually. They just pay an estimate of you loss! However books or movies etc are called collectables. If a record of each individual book is recorded it can be presented to the insurance company and they have to REPLACE THEM OR THE VALUE THERE OF !
CLZ Books is the answer, the perfect answer. Easy to use, loads book and its details in a flash. Copy on my phone + phone icloud back up+ CLZ icloud, back it up and they do it free.
Do you have a collection of books you love and re read. Then buy this app. If your house/ apartment burns down you have the proof you are not trying to commit fraud. I photograph my furniture and all valuables.
CLZ books 5 stars+ and sleep easy. Also if you are looking in a book store you can check on your phone if it is a book you already have with just an updated flashy cover."

Love it but help for cloud!!

"This is exactly what I wanted! Uploaded my books from my Mac and worked very well. Now how do I upload my books to the Cloud all together? I can only manage new books but not existing ones. Help?
Alwin and his team give the best customer support i've ever seen, worth getting this just for that."

"The last release has brought what I want in Android: stand alone app that can be synchronized with CLZ Cloud. I have not gone thru but really love it."

" I am so grateful for the CLZ book application. It is so practical and so helpful and so simple to use. I have a large personal collection that I love to share with people, and this allows me to carry it on my phone and allow them to search for a book they would like to borrow. And then, I have a way of logging my loans for my records. Thank you for the work your company in creating this tool. I wish you much success in 2015, and I plan on being a long-term user."

Best Home Library App

"This is the best library app that I have found in the App library. In my case, I use the PC desktop version (there's a Mac version as well) as my central point of management. I use CLZ Barry app (from this same vendor) to scan barcodes using an iPod Touch and then transfer the scanned codes to the PC. I then, periodically, upload the desktop database to the CLZ cloud and then use this iPad app to download the database to my iPad for use/viewing here. "

Werkt goed en snel

"Met de geïntegreerde barcode scan heb je alle nieuwere boeken snel ingevoerd. Alle boeken zonder barcode worden ook snel gevonden via handmatige invoer. Met name de cloud synchronisatie functie is handig voor als je meerdere devices/gebruikers in huis hebt. Cloud synchronisatie werkt perfect. Functionaliteit is meer dan voldoende en ik kan ook zonder de desktop applicatie."

"Have used the desktop app for years. This is the perfect companion app."

A must have!

"A must have for true book collectors! I have the comic and music apps also."

Works as it should

"I'm excited to see what the newer versions bring .. also running with older book collector versions, so you do not always acquire the latest version ;-)"

April 10, 2014

The greatest

"This is the greatest book collection software and app that is out there!! The price is right and it works very well with my phone and tablet. I can take my collection with me everywhere that I go. Try it!!!"

Great book lover app

"Great app! Scanned perfectly 12 books of 12 so far. I hope you'll add more options in future, like page number bookmark, book reading status bar, etc."
