Here's what customers have said about CLZ Books

Excellent cataloging tool
13 November, 2015
“Excellent on all platforms. Very easy to use and adaptable for extra details one wants to add. Very good support service. Only negative - Wikipedia links are sometimes to wrong authors with same name.” — Wiradanuprojo
Great App
30 September, 2015
“The app makes adding books much simpler than the full PC program. Display, filtering and sorting are excellent. Some kind of built in interactivity with social media would be really useful, though.” — Gary_Carr
Proper plots

“My manga and books now have proper plots. No more relying on core.” — Stickerclub
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.” — *Asterisk*

“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.” — Moonflower1952

“Version 2 is great and now offers the same functionality as the is versions. No longer to to connect to PC so good to use on the go.” — Dave Stears
Love it but help for cloud!!
25 January, 2015
“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.” — Bianca MG
