So happy!
This app has saved my wife & me SO much money by keeping us from buying duplicate books that it might as well be free! Simple & easy to use - in fact simpler than ever with the new update! And when I had a minor issue with the Statistics feature, I asked for help and was promptly replied to with clear instructions that fixed my problem. As stated, so happy with this app!

To the rescue
Many thanks for the re-set. Everything seems to be working fine now.
I must stress how much I always appreciate the speed and efficiency with which you and Sytske come to the rescue. It really does matter!

Enjoy this software
I enjoy this software and it really helps when I see things on sale in stores to be able to check and see if I already own it.

Excellent database
CLZ Music is an excellent database, but I shouldn't be surprised. I also have CLZ Movies and CLZ Books which are excellent databases for my films and books respectively. All of them get regularly saved to a cloud so if the worst happens and I can't open the CLZ version, I can go to the cloud and build another from there. If not, contact them for help which is helpful and will soon have you up and running again. I would say I have used these databases for more than 15 years now.

The Best Out there!
CLZ continues to produce winning apps, this one is no exception. Hands down the best way to keep organized and avoid duplicating a movie. Super easy to use to locate, add, or adjust your collection. Next up…action figures?
I’m so glad to be connected to the company and also it’s worth noting they are VERY responsive to the collecting community…they truly care!

Today is New Comic Book Day, so the perfect day to release the new NCBD feature for your trusted Add Comics screen! We bring you a completely redesign of the Pull List tab, you know, the rightmost tab of Add Comics. At the same time, we are renaming the tab to “NCBD” as we figured that this was a better fit of what the feature does, especially after today’s complete redesign.

Here’s what’s new:

  • In the Add Comics screen, the fourth tab is now called “NCDB” (previously “Pull List”)
  • Navigate over weeks with next/previous arrows, or click on the week/date for a dropdown
  • Release list now directly shows the issues, as a Card View with big images
  • Click on an issue to see all its variants
  • New: filter by “#1’s”  to show all #1 issues (so all new series)

  • Sort issue list by Popularity or Alphabetically

To try the new NCDB tool for yourself, open the Add Comics screen, then choose the 4th tab called “NBCD”!
