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.

May Catalog now in Core!

May 07, 2026


Our content managers have worked hard to get all the new titles from the April catalogs into Core.

Some new titles include:

  • Dark Knights of Steel, Vol. 2
  • Buffy The Vampire Slayer, Vol. 3
  • Doctor Who: Circuit Breaker
  • …and much more!

In total, we counted around 2200 new entries for this month!
They are now all available to add to your “On Order” list in the CLZ Comics app.


It’s that day again. NCBD! A bunch of new titles for you to choose from by all of the major publishers. Here are a few books that were handpicked by our content managers:

My pick (CLZ Rowdy) for this week is: If Destruction Be Our Lot #1. Humanity is extinct and all that remains are the robots who once helped us. The robots who once helped us are happier now, doing their work without human interference. But not Abe. He believes there must be something more out there.

Finally a new Avatar comic!! My pick (CLZ Taco) this week is Avatar: The Last Airbender – The Kyoshi Warriors #1 Really looking forward to what this story has in petto for us. Only 3 issues unfortunately but hopefully a good read!

A fresh take on a 21st Century classic! Ben 10 #1 So basically Absolute Ben10? Take my money!! This is supposed to be the definitive take on Ben 10 from the team that created him. This is definitely my (CLZ Justin) pick this week. Loved the first animated series and alien force? Then this is a must read for you.

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!
