A must for video Game Collector
I was looking for a simple to use application that would be able scan barcodes from my European Japanese and Us games. Most of other applications do one or the other. With Clz I find games from all continent / console / version (deluxe / collector / standard) et variants. Add to that the cloud save. Really a must. Wouldn’t change from app for any other and trust me I tried plenty.

Just as incredible!
I have used the Desktop version for years, and this is just as incredible! Being able to carry my entire database of movies with me as I thrift shop to expand my collection is awesome and cost saving (I have double and even triple bought a title).
The customer support is helpful and friendly as well. I have not found a better company for keeping track of your items. I also use their Music and Book databases as well. They even have a Comic Collector app as well.

CLZ Technical Support
The CLZ support team is amazing. They responded to my questions in less than 24 hour, providing step by step instructions to resolve my issues and followed up for additional questions. I highly recommend their Movie Cloud database.

Best comic app, and customer service
I have been using this app for a long time now, and it gets better every year. Customer service has always been quick to respond, and helpful. Having over 5,000 comics this app is required to keep collecting. Worth every penny.

v10.7.3: A couple of bug fixes

Apr 17, 2026

Fixed:

  • Further tweaks to the down-syncing from CLZ Cloud
  • Book details page accidentally included the “Custom Fields” sections
  • Add Books, Edit and Action buttons could not be used if images were still downloading in the background

Another week, another NCBD. It’s no surprise here, that Absolute Batman #19 is the biggest book this week (as can be seen in our Most Wanted on Monday). No less than 54 different covers for this issue! Absolute craziness? Our content managers might even have to be send to Arkham Asylum after adding this many into Core. Don’t think we’re done yet. Image releasing their new series: Fireborn. A bit of a smaller week for Marvel… Here are a few books that were handpicked by our content managers:

Radiant Black #41 Are you caught up with this series? I sure am! Horizon is Chicago’s hero. Radiant Black needs Shift’s help to sneak into a lab that’s withholding secrets. Will they succeed?

Absolute Batman #19. This issue brings us the introduction of Slade Wilson, Scarecrow and the Robins within the Absolute universe. This should definitely be a solid after we know what were getting next issue.

Cheers, mate! After a bit of waiting, we’re back with a new issue of Redcoat #17. This should be a nice set up for what’s to come. I’m especially fond the Kyle Hotz cover!

All comics releasing this week can be found in the NCBD tab in your add comics screen. All new releases have been carefully cleaned up, with lots of info added! Be sure to check them out in the app. Either when you hit your comic shop or, when back home adding your stack you’ve just come home with!

Happy reading!
