Comic Database Software

This is an awesome app for tracking comics. I love that I can add comics using images or scanning the bar code. The wish list feature is great too; perfect to reference when you're at the comic shop. Being able to set default values for scans is also pretty cool.

This app is a must have for anyone that collects comics. There are so many different ways to view your collection and adding new books is very simple. This app has given me such a better understanding of my collection as a whole. I truly suggest this app to people who collect all the time. It’s a great thing to have when you’re looking through back issues at the store as well.

Been using this app for several years now. Quick and easy to use it allows me to quickly add new comics each week and avoid duplicates when fleshing out the back catalogue. For many years my memory was enough but now there’s too many to recall and with so many variant editions I just couldn’t keep on top. The integration with cover price is good too but is a significant cost more though totally optional.

I’ve been using the app a couple of years now. It’s great! I’ve got my entire collection on the database now. It’s so easy to find comics in my collection and, even more importantly, I can quickly find what comics I need. Very handy at conventions when you’re flipping through a bin. Could not recommend strongly enough!

Great organization for my collection!

only using a few weeks. 2025. now in 2026 and 3 months into . it's an amazing app for all your storage of data as regards your comics. if it thinks it valuable it puts a value on it in which I think is great. price is reasonable and the service excellent

This is a great app for cataloging your comics and knowing their current value.

Never leave home without it. In another city bumping into a comic shop. Going in without reservations because your list is in your pocket. No more coming home with doubles. Or missing out because you thought you had it already. You know the feeling!

Had a search issue that was immediately addressed and fixed. Highly recommend this app for anyone looking to catalog their collection.

This app was recommended to me by a guy I was talking to in an antique store looking for comics. I made the comment I couldn’t remember what books I had and what I didn’t. He told me to download this app and I wouldn’t regret it. You can scan barcodes and/or the covers and it’s super fast. I’ve just cataloged a hundred books in about 20 minutes.

For all you comic collectors out there, this is the best app for managing your collection. It lists all the variants and different printings of a given book. You can sort by a variety of topics(artists, writers, the list goes on) . The customer service is 2nd to none. They address whatever issues you might have and respond quickly.

Best comic cataloging app hands down, if I had to pick my top five comic cataloging apps this would fill all five spots.

This app has helped me when I go comic hunting by using cover art, displaying missing comics in runs I want to complete. So much easier to organize my collection and to remember what I have and what I don't. Thanks to this app I have been able to even save money by not buying duplicates over time.

This is an outstanding app, I love it! The performance and look and feel is professional grade. It is so quick and easy to scan into the database. I had 1400+ silver age comics, and got them entered and organized in hours, not days. Every possible attribute can be edited, and the scanning sets very reasonable defaults. Whether you are a buyer/seller, or just like your collections well-organized, this app is worth every penny.

Most useful app for my comic collection.

This is an outstanding app for managing comic book collections, large or small. The app makes it easy to add books, add notes or details about a book, and links to a source that allows it to pull in values. Lots of cool new features are added monthly and it's clear that the CLZ folks are very passionate about it.

Make a Clz for trading and sports cards!!!

Love this app! I have been collecting comics books for many years and this app enables me to easily gain knowledge about my collection. Knowledge on minor and major keys, knowledge on most owned characters, writers and illustrators, and knowledge on book values. Statistics can be updated at anytime with a simple click.
The app also helps me organize what I own, what I want and what I’ve read. A++

This app has made organizing my comic book collection easy. I have over 21 Long boxes to input. I love that you can snap a picture and enter the comics. Also, there is an add-on if you want to use cover price within the app. Keep up the good work.

I have about 650 raw comics and 50 or so graded. I love how easy it is to just scan my comics into my collection, either by barcode or cover. I can then add additional info like grade, grading company, purchase price/date, etc. Very flexible. When I sell it I can add my sell price/date and move it to “sold” but it always stays visible if I want to refer back to it.
Also, the direct connection CLZ offers to COVRPRICE lets me see my collection’s value as well as individual issues. It’s the perfect combination of an easy way to catalog my collection as well as value it and update as needed!

I wish I knew how many years I have used CLZ. More than ten at least. Or that is how it feels. No other database, app, or fly by night operation will ever be as complete as CLZ. I remember having the CLZ version for Books and Movies. Anyway, CLZ is by far everything you will need to be able to catalog your collection. Over the years they have made so many improvements that it is unrecognizable from when I started with CLZ. The UI continues to get better. The layouts, added features, and the non-stop updates are what makes it the Industry standard for any collector. I suggest making two collections, One your owned comics, and the other what you need. These as separate folders will help immensely. And use the features, CLZ can do a lot and when you start utilizing its powerful database your collection will start to manage itself. Honestly the only thing I am waiting for is when CLZ connects your collection cover images as a rotating Wallpaper for desktop or laptops.

For a number of years, I have used CLZ on my iPhone and on web browsers - both my Mac at home and my PC at work (with the browser-based version being a second subscription that can be bundled with this app for a discounted total). This is the best app for my needs that I have ever found.
The problem with some apps is that they do not allow enough customization. This app has a lot of flexibility. Even if you start organizing your comics one way and then realize that you need to change something, CLZ has got you.
Also, the developers are the nicest and most customer service friendly people I have ever dealt with. No question or request is too small. They really listen to us - the app users. They are continuously making the app better - based on an ongoing list of requests from the customers - not something you see from every app. They literally come out with some cool feature every month or so and usually there is one or two significant changes every year. At some point, they are going to run out of things to improve - because it's already great!
Well, as you can tell, I could go on and on. CLZ is an app that I will surely subscribe to and treasure for the rest of my life.

I have my entire 4,000+ comic book collection organized on the app, and I also have the CovrPrice subscription so I can see up-to-date pricing/value data for all of my books. The cover scanner is awesome for both logging comics & pricing new ones. Super thankful to the team for all their hard work!

I started collecting as a kid in the 60s and then again in the 90s. Now that I’m nearing 70 I wanted to track my collection and CLZ made a daunting task super fun and easy. Thanks CLZ!

Want an app that makes you spend more money on comics (in a good way)?
This is the app for you. Stick in all the comics and next time you are at a comic shop there will be no "have I got that one?"
The integrations with comic prices is genius. A brilliant collaboration.
To be honest I bought the PC version first and blasted through 500+ comics using the barcode scanner. Then synced it to the cloud and bought this app and there you have it. My whole collection available by my geeky hands.

Super convenient app for cataloging and keeping track of all of my books.

The painstaking work that goes into this app astounds me. It benefits the comic community greatly. Almost every book you can think of is in here, making cataloguing very easy. You can separate collections, connect to CVRprice for value, and change views to see your collection how you like. Adding notes is fun, especially to say if the book is signed. For $20 a year you cannot beat it.

Thanks for offering this to us. I used to use index cards and multi ring binder as a "hard copy" ever since the 90's. This app allows you to be mobile with your collection, to share with others or to have that instant access to all of it, what it looks like, it's value and where to go to add to it. Worth every penny, I'm a fan. Keep up the good work you do, always improving your app. Thanks for your dedication to this collectable.

CLZ is hands down the best software out there for managing your comic collection. Has tons of features, and is super customizable to suit a specific person's needs. The CLZ Core is a great database that has almost every comic you would ever need... but if it is missing one, just contact CLZ and they will add it!
I use this app multiple times a day, and would be lost without it. HIGHLY recommend it for a new or long-time collector alike!

It is very handy if you are at the comic shop and you are looking through back issue bins. You can just pull up the app to figure out which issues you are after. It also works well for new issues too. As many variant covers there are these days, the app has every issue with all the variant covers listed. I'm not sure what I'd do without it! It also has functions that let you keep track of signed books and if you have them slabbed, down to having the various labels cgc uses.
