CLZ Movies is the best
Highly recommend! I have a large collection of movies and tried various options to catalog and track my collection. I found this app and have never looked back.
The best option is that the software scans the barcode to add the movie quickly to the collection. For most movies it takes a few seconds to add, and no further typing or searching is needed. If the movie is not found in their catalog, it can be added manually. I also use the location option to log where the movie is stored to be retrieved easily.
The app is also constantly updated with new features. It is worth every dollar.

Impressive customer support
WOW ... very impressive customer support. Please go to the head of the class.
I've been using CLZ products for many years and have never been disappointed with their utility and ease of use. My library has over 2100 titles and I couldn't create or manage them without CLZ. Thank you for being the obvious choice.

Great for managing collection
I’ve been using CLZ for several year and I’ve found it’s an easy app to scan and log what books I have (so I don’t keep buying dupes on accident). This was especially helpful when I was trying to complete my full run of X-Men to know which books I was missing. On top of that, I had an issue with my account recently and got locked out and support responded back quickly and got me unlocked. Nice personal touch.

CLZ App is incredible
The use of the program is easy to use, the dual way of adding to your collection is awesome in itself. The development team go above and beyond to answer your questions, this app is well worth the time and money invested 6 stars!!!

Latest CLZ news


I know, I know, I am one day late. Yesterday, June 30, we had a celebration with the entire CLZ team, celebrating a big milestone for the company, as we had reached a record number of subscribers for our software and apps. I am afraid I can’t disclose how many, but it is a LOT 🙂 So this means the CLZ Team can keep investing in more improvements, new features and the quality and completeness of our Core databases!
We met at a local hotel, for a speech by yours truly, then drinks, then dinner. we stayed at the hotel overnight too and ended the festivities with a luxurious breakfast buffet. Lots of fun!
The team is back at home again now, ready for work (and NCBD of course!). For me, time to write this June 2026 newsletter. Here we go:

Maybe the most important news is: we are very very close to the launch of the Custom Fields feature for the mobile apps! ETA: mid July! More info below.

Finally, this month we again released two nice features/improvements for the CLZ Web software. Cover thumbnails in the list view, and better keyboard support, mainly in the Edit screen. Full details further down.

The newsletter topics today:

  • CLZ Web: Add cover thumbnails to your List View
  • CLZ Web: Better keyboard support
  • What’s cooking?
    • CLZ mobile apps: Create (and Sync!!) your own Custom Fields
    • CLZ Music Web: Export and Print *track* lists

NCBD! A slower release week due to the summer. Need something to cool off? Marvel’s got you covered with their Swimsuit Special! With 21 different covers no less. Absolute Martian Manhunter’s final issue is releasing today as well. Tons of great books to pick up. Here are a few books that were handpicked by our content managers:

CLZ Taco’s pick this week: Radiant Black #43. The previous issue left us on a cliffhanger, really looking forward for this weeks issue. This time bringing in a new artist: Giona Zefiro.

CLZ Rowdy’s pick this week: The Scorched #52. Jessica and her team are now trapped behind enemy lines while two separate armies close in. Will they escape before caught find out with me this weeks issue!

CLZ Justin’s pick this week: Star Wars: Rogue One – Saw Gerrera #1. Saw Gerrera is here once again, this time with higher stakes: information that would provide a tactical advantage that could shift the balance of power in the Rebels’ favor! But is the price to be paid for that information too high?

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!

What trouble will it bring Hellboy? Written by Christopher Golden & art by Daniele Serra!

My pick (CLZ Justin) this week is: Absolute Wonder Woman #21B. A new chapter in the Absolute Wonder Woman saga, this week a new 2 part story arc titled: Friends & Neighbors. The cover I picked, connects to Absolute Superman #20 & Batman #21. They’re going to look on my wall!

Two nice improvements for CLZ Web in one go. First, you can now add a cover thumbnail as a column in your List View. Next to that, we spent some time improving the keyboard support in the Edit screen.

On top of that, we’ve now also added the possibility to install CLZ Web “as an app” to your computer.
