The Best
Over the years I have used several Database apps for my collections. Without a doubt, CLZ is the absolute best. It has so many features to help they cannot be listed. It has everything you could possibly want in a database.
But above all else is there Customer Service. Prompt, courteous, helpful. Absolutely wonderful people. A wonderful app and great customer service.

Thank you very much, great service. I'll try to not do that again!
I do really like your app as it makes cataloguing my collection so much easier.
Wishing you a merry Christmas and a happy new year.

That was quick
That was quick, straightforward, and without red tape. As a very old customer, who took a break due to health, I am grateful and certainly know how to appreciate that.
Have a wonderful Christmas and a happy New Year.

Expedient support
Many thanks for the expedient support and it's worked a treat as I've used the forgot password feature to update and successfully log in to the mobile app with the new details.
You provide an awesome suite of tools and services so I think it's nice to highlight and celebrate the global impact of what comes from hard work and passion from people like yourself and to reflect back an echo of how these products become part of our routine and how they feed into the storytelling we have with others as that's the real joy of a lived collection.
Your help has been very much appreciated and hopefully there's a lovely weekend ahead!

Excellent apps
I have just started with the books app but been using your Music and Movies apps for years now and both are quite excellent as I have thousands of each of those.
Now on to books, LOL.

Almost Christmas but look what made it just in time: NCBD!

ThunderCats Ho!(liday) Special 2025 #1 While on a mission in the snowy mountains of Third Earth, the ThunderCats stumble across Snowman, the last of his people, on the eve of the Festival of the Claw — a day of celebration, food, and gifts, and a time for Snowman to pay tribute to those he’s lost. With no others of his kind remaining to pass his traditions on to, Snowman shares them with the ’Cats, who understand all too well the need to persevere in the face of overwhelming loss.

Meanwhile, just outside of Snowman’s mountaintop village, Queen Tartara’s royal guard are preparing to use the holiday as a perfect opportunity for a surprise attack. But even on this hallowed occasion, not every Thunderan has let down their guard!

Black Panther: Intergalactic #1. T’Challa, the King of Wakanda, faces the challenge of uniting all of his kingdom — on Earth and in the stars! Before he can begin, though, someone — or something — steals him away to a mysterious planet where the Black Panther must fight for his life! SHURI, his sister, works to find him — but with the king and princess distracted, will someone else seize the title of Emperor of Wakanda?!.

Sensation Comics #38 Facsimile. When Wonder Woman decides to play Santa Claus for some children who have lost all hope, she never would believe it would lead her up against a gang of gold thieves.

Happy Reading!

v10.6: Several improvements for the Cover Scanner

Dec 16, 2025

Since we launched the Cover Scanner feature, just over a year ago, it has grown into the most popular method of adding comics and checking values. Four months ago we already did a big update to the feature, to make it easier and fast to use (less clicks) and to add a much requested Queue Mode.

Today, we are doing another update to the Cover Scanner, to better help you select the correct match:

  • Improved recognition of Newsstand vs Direct editions
  • A new Variant Filter to always hide specific variants
  • Popularity indicators for each match

Also new in this update, a small but helpful addition to the Check Value screen:

  • The Grade selector now has a new “-none-” option, so that you can easily check values without setting a Grade.

Import custom episodes from Movie Collector

Dec 11, 2025

If you have custom episodes in the legacy Movie Collector Windows program, you can import them to CLZ Movies Web. This is a one-time import meant for users who are making the switch from Movie Collector to CLZ Movies Web (and stop using Movie Collector Windows).

To do this, you need to follow some steps which can be found in CLZ Movies Web:

  1. Click the menu top left and select ‘Import/Export’
  2. Click “Import custom episodes from Movie Collector’

Important: if you currently have User Defined Fields in Movie Collector Windows, and you would like to import those before switching to CLZ Movies Web, please do not use this tool until that feature is available somewhere early 2026.


This one is for the Android users!

Our Android developer Pim was working on the app’s main screen and he saw some opportunities for improvement. Mainly to reduce slowness and stuttery behaviour when navigating back and forth between the folder list, the movie list and movie details page.
So instead of starting on the next new feature, we gave him a few days to refactor the code and improve existing functionality.

The result of Pim’s work is live now, in version 10.2.3 of the CLZ Movies app.
We have been testing the new update quite a bit and we think it feels a lot snappier and smoother, especially noticeable on larger collections.

We hope you will notice the improvements too and that it will make you enjoy the app even more!

How to update your app to the new version:

  1. On your device, open the Play Store app.
  2. Search for “CLZ” and select the CLZ Movies app.
  3. Tap “Update” to update the app.
