Reviews from CLZ users
I am an early childhood special educator and it is my hope to be able to add more details to each of the books I have logged in order to sort them by subject/theme to support how I utilize my library in the classroom (I am currently just logging my home book collection, and have yet to tackle those books that I have at school).
All in all I am so grateful for the app - it is just what I needed and has made cataloguing the books a breeze!!
It works now!
My film and tv library is close to 1000 and my books nearly 300. I visit charity shops regularly and without the help of these 4 apps I would be buying multiples all the time.

We have another exciting week of new comics and variants ahead! Let’s take a closer look at this week’s highlights.
First up is Mary Jane: Face It, Tiger #1, a giant-sized one-shot celebrating 60 years of Mary Jane Watson. It features three stories set during different eras of MJ’s life, following her journey from party girl and fashion model to superhero and symbiote host. The issue also includes an epilogue offering a glimpse of what’s next for Mary Jane. If that doesn’t pique your curiosity, we don’t know what will!
Our second highlight is Batman, Vol. 4 #12, written by Matt Fraction with artwork by Jorge Jiménez. This issue introduces Verity Pennyworth, a brilliant new ally—and potential new butler for Bruce Wayne. We can’t wait to see how it unfolds.
Finally, we have Gun Honey: 5th Anniversary Oversized Special #1, written by Charles Ardai with artwork by Ang Hor Kheng. This massive commemorative edition celebrates five years of Joanna Tan’s adventures with an oversized presentation of the original first issue. Whether you’re just discovering the series or have been a fan since the beginning, this is one issue you won’t want to miss!
All comics releasing this week can be found in the NCBD tab on your Add Comics screen. Every new release has been carefully cleaned up, with lots of extra information added, so be sure to check them out in the app—whether you’re at your local comic shop or back home adding the stack you just picked up!
Happy reading!

This is Alwin, head of CLZ, with the July 2026 edition of the CLZ newsletter. And this time, it is a “one-topic” newsletter, all about “Custom Fields” (previously known as “User Defined Fields”).
This week, on Wednesday, we finished our biggest project ever, something that most of the CLZ team has been working on since late 2025: the implementation of the “Custom Fields” feature. Near the end of February this year, we launched this feature for all 5 flavors of the CLZ Web cloud-based software. Then, over the past 2 weeks, we released big v11.0 updates for all 5 CLZ mobile apps, bringing the custom fields to the “small screen”.
Additionally, with the release of the mobile app updates, you can now cloud sync your custom fields definitions and their data seamlessly between the Web-based software on your computer and the mobile app on your phone or tablet.
Actually, that syncing was the most complex and time-consuming part of the entire project and also the main reason why we procrastinated on this custom fields project for many years 🙂 But we finally made it happen!
Now, let me tell you all about this month’s major v11.0 updates for the CLZ mobile apps:
Fixed:
- Crash when opening comic details page, related to CovrPrice links
- Crash when down-syncing series with empty displaynames (should be rare)
- Freezes when opening some series in the main screen
