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."

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 ;-)"

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."

"Wonderful App! Just used it for a day; loving it!"

Best mobile catalogue

"I'm a big fan of clz apps, but the new versions are just superb. I brought the PC version as a spur of the moment choice. But now with the ability to link via mobile, I'm in my element. The recent updates and better screen layout on the iPad have just made the best better!!"

"As a preacher this app is great for keeping track of which books are in my library. I can keep track of every feature imaginable and have no complaints other than the price but it is a great product and well worth it!"

CLZ Books

"The mobile app accesory to Collectorz excellent book organizing database system. Tracks your Ebooks, too. Collectorz offers a complete suite of custom databases to help you organize your life. They are constantly improving their product and offer customer service and support that many other companies can only dream of. You may be able to find cheaper or even free aps that claim to do much of what Collectorz offers, but you won't find better value anywhere."

Great app

"This is a great app for tracking books owned and read and with the desktop version you have incredible database editing capabilities. I've tried a number of less expensive apps but none approach this one. User manuals are comprehensive and when I messed up my account by using two different email addresses, technical support fixed the problem in less than a day."

"This thing started out as a just very useful (and fun) tool and they refused to stop improving it. Combined with their SUPERB customer support, this app is every bibliophile's dream come true! I also own their desktop software and subscribe to their online database hosting. No complaints there, either."
