It’s going great!
My wife and I inherited over 300 late 1940s through mid-1950s comic books and needed to catalog them. Quite a fun experience! Your app makes it much easier.

Comic catalog
You are outstanding! Please keep up the good work. Mark really likes your program, and it’s nice to have a “catalog” of his comics.

CLZ
I have been using it for years , the best app for cataloging your American comic books. It can connect to your Covrprice account as well and approximate value. Lots of other bells and whistles.

Fantastic app - great range
Just a fantastic app for keeping track of my collection - I use the books, movies and music CLZ apps too.
Great catalogue - only have to add some indie titles and UK reprints (from last year).
Very impressed with its stability, interface and features.

Perfect for collectors
I’ve been using CLZ for several years now. It has improved year over year with new features and the price has remained pretty much stagnant. The developers are extremely active in the community and responsive to feedback and issues. This was the first collection database I tried for comics and never looked at a second. As long as the service is active, this is where my collection will be catalogued.

What a fantastic app!
Oh my goodness, what an app! I’m having so much fun cataloging my comic collection. The cover scan feature makes the process super quick and easy. Key issues and appearances are clearly identified, the layout and interface are solid, the yearly subscription price ($20) has already paid off in less than a month, IMO. Scanning new additions into the CLZ app has become such a great part of the collecting process. Can’t recommend this app enough!

Couldn't be happier
Great app, so far have cataloged 100+ comics and works every time. I also use their app for movies and couldn't be happier. If you have comics or movies and I think they have a couple other database apps I'd highly recommend.

Great app and even better customer service!
Love this app, use it to catalog all my comics and ensure I’m not doubling up when hunting. It makes it easy to keep track, has information on Key issues and can even help show the value of your collection.
Even more I messed up when creating my account and they were so quick to respond and help me get my account setup the correct way very quickly.
Couldn’t be more happier with the app and the level of customer service I received!!! Thank you!

Wonderful App
I recently inherited my late stepfather‘s comic book collection and believe me it is vast I was becoming overwhelmed very quickly with the need to try to manually catalogue every single comic in order to know exactly what I was working with and it was very daunting. But then a good friend of mine recommended this app to me. As soon as I downloaded the app, I could see the benefits right away! Thank you. CLZ.

Game-changer
I just wanted to take a moment to say how incredibly grateful I am that I found your app. I recently inherited thousands of comic books and honestly didn’t know where to start with cataloging them. It felt overwhelming at first.
This app has been an absolute game-changer. It’s so easy to use, fast, and intuitive. My family and I feel less stressed and we are actually excited to go through our late brother’s collection. What seemed like an impossible task now feels totally manageable, and that’s all thanks to the thoughtful design and functionality you’ve built into this app.
Thank you for creating such an amazing tool—it’s exactly what we needed.
Box 1 complete, only 20 more to go!

No better way to catalog your books. it has nearly everything in its database. Is a life saver when out hunting books and can save you a ton from buying duplicates and knowing exactly what you need.
On top of everything else, the support is top notch and they are very active on their facebook page as well. I just want recommend this product to every collector enough.

Excellent comic book inventory
I have been collecting comic books since 1962 when I was 12 years old. I have accumulated thousands of comic books. Until recently I had no way of cataloging my collection. I found this app, and it’s been simply amazing. I have been actively entering my books to the inventory for the last year and a half. The features of the app are so helpful and it is so easy to enter each comic to the inventory.

Brilliant app
I've got over 600 graphic novels and probably double that amount in regular comic books and I had planned on cataloguing my books by entering them all on a spreadsheet. (It would have taken ages). Then I found this app and it took next to no time to just scan the books or take photos of the front covers.

I like!!!
So far it's great to catalog ur inventory!

CLZ has been great
This app has been incredible in cataloging and arranging my personal comic book collection of over 5000 comics. The price, usability and backend support is top notch and worth every penny of the yearly subscription price. I just wish they had a one time lifetime subscription because I’d buy it as soon as it went live.

Time Saver!
So I had never cataloged or valued my collection of over 3,000 comics. Wow, this app was a major time save and gave me perspective of the market. Every collector needs to be using this!

The best app so far to catalogue comics. The interface is intuitive and it's very simple to use. They offer many customization options to suit a lot of organization needs.

Simply awesome
Fantastic app for cataloging your comics. Tons of useful information, including series, variants, artists and more. They are super responsive to questions and issues and are constantly updating key information. Join the Facebook group as well for more general advice and tips. Very engaged group and couldn't be happier.

Best comic book catalog app ever!
The process is very simple. Scan front cover of comic or bar code, and done! I’ve wanted to catalog my collection for years, but hadn’t found a good app to do it. I can across CLZ Comics and it has been a game changer!
I enjoyed every minute of scanning as I went through my collection. The app also provides the current market value for my comics. Sweet!

Excellent!
I have to thank my son for telling me about this app. It's so easy to catalog my comics and know what I have instead of trying to remember.
