Comic Database Software

I am really enjoying the app. It works very well and I have had no issues. I am amazed how easy it is to add comics to collection. I already have over a thousand scanned in. It found every comic I had in your database. I love the look on the iPad and it’s nice seeing my entire collection without going into boxes.

There is nothing on the market that has the power, flexibility, and function for cataloging comic books and graphic novels. Support is responsive and knowledgeable. Highest Recommendation!

Fantastic app for comic book collecting and organizing!

Great for keeping up with all of your comics and when needed responsive to fixing issues.

CLZ is a fantastic app for all comic collectors. Tracking, detailing of books and consistent updates are especially appreciated. The best part is how responsive the CLZ team is when there is an issue and you reach out for support. They not only respond quickly but resolve the issue in great time. Professional is the best way to describe the CLZ team.

I’ve been using this app for several years and it has been very helpful for me to keep myself current and hunt down the books I need for my collection. Well worth the cost. And, the fact that Alvin and his team constantly update and improve the app makes it worthy to keep for any serious or recreational collector.

This app has stopped me from buying doubles. The cataloging is so so so good. I love that it connects to covrprice if you would like. The only thing it is missing is a tone when I complete a run, or a trophy!!

I’m a huge fan of the app. Comprehensive, dynamic and able to track your collection. Customer support is quick and work hard to address issues. Both my son and I use it for our collections.

A great software that helps me organize and just getting better all the time. Customer service is also very helpful and prompt. Definitely recommend.

I love how this can organize my growing comic collection. Very useful for finding missing issues.

I would recommend this app to every single collector out there.

I’ve been using CLZ to organize my comic book collection for a while, and I love it. Having my entire collection at my fingertips when I walk into a shop really helps prevent buying duplicates.
I also really enjoy the features for managing graded books and signatures. Highly recommend CLZ—the app is solid and their support team is top-notch.

I love this app. It makes keeping track of my comic collection incredibly easy across devices and on the web. As my collection continues to grow, adding books on the go is fast and intuitive, which is a huge plus. Finding missing issues and adding them to wish lists is simple and extremely useful when I’m at the comic shop. I also appreciate the ability to create and manage multiple collections, which adds a lot of flexibility.
The CovrPrice integration (with the optional add-on) is especially valuable for tracking pricing and overall collection value, making CLZ not just a cataloging tool but a true collection management platform. The app is well-designed, reliable, and clearly built by people who understand collectors’ needs. I highly recommend CLZ to any comic lover, whether you’re just starting out or managing a large collection.

Awesome service, great companion when I go comic shopping.

Great App, must have for any comic collector with the most helpful and responsive team to support.

Best app on the market!! Easy to use, tons of customization!! Top level support!! You won’t be disappointed!!

CLZ is hands down one of the best tools I’ve found for managing a comic collection. The app is packed with features that make tracking books simple, clear, and actually enjoyable. Everything feels intuitive from the start, and adding books is fast and smooth. One of my favorite features is the cover-scan option. It makes cataloging new pickups effortless.
The depth of filtering and sorting is impressive. You can break down your collection in just about any way you want, down to the smallest detail. It’s also saved me from buying duplicate issues more times than I can count. The eBay integration is a huge plus when you’re hunting for that last book to finish a run, and the built-in value checks based on grade work well for quick reference.
Customer service deserves special praise. Responses are fast, helpful, and genuinely thoughtful. The team clearly listens to user feedback and keeps rolling out updates that matter to collectors. Being able to export my collection into a spreadsheet is another feature I use often.
If you’re serious about comics and want an app that keeps your collection organized, accurate, and easy to manage, CLZ is worth it.

I’ve been using CLZ for over 8yrs now to manage my 10,000+ issue collection and it’s a life saver! Great features, makes collecting even more fun and they’re always improving or fixing things. Well worth the price!

I needed something easier and more intuitive than Excel to inventory my rather large comic collection. After doing extensive research, I went with CLZ. It's very easy to input books and the information it provides is amazing. CLZ was a very worthwhile investment and I would definitely recommend this to all serious collectors.

I have been using this app for a number of years and I absolutely love using it. Using the photo feature for adding comics is easy and fun. Connecting it with CovrPrice to get updated prices is a no brainer. The user interface is smooth and very intuitive. One of the best things about this app is that they are always making updates based on user feedback. I can’t recommend this app enough.

I found it very easy to catalog and price my collection. Barcode feature was very helpful. When I was confused about variant editions coming up the support team was very helpful. I’ve enjoyed using CLZ.

It's super easy to catalog my collection by title or scanning covers. It syncs with Covrprice to keep me current on my comics' values. I can maintain wishlists and prioritize the books accordingly. I can't recommend it highly enough.

I absolutely love this app. With large collection it helps me keep so organized and also keeps me from buying duplicates of what I already have. I have saved way more money not buying duplicates than the annual cost of the app. I don’t pay for many apps but this one is well worth it. From being able to categorize my collection, note what I have read, mark series complete, search by creators. There isn’t much it can’t do.

Legit Review!! This is the #1 app for managing your comic book database in terms of: Price, Functionality & Portability! Price can't be beat for value. Functionality is bonkers with UPC and cover scanning to add inventory from CLZ Core makes it easy! Portable between my tablet, phone and PC! Embedded links to eBay and CGC are examples of CLZ's commitment to making this app so user friendly! CLZ takes my comic book collecting hobby to the next level for real.

Helps me keep my collection in order. Over 40 years of collecting. Over 10k comics and counting. I'm happy.

So easy to add new and verify whether or not I already have a certain comic! Love this app! Makes my collecting and collection easier to manage! Just scan the barcode or cover, and your comic comes up! Best comic cataloging app on the market; bar none!

I have used this app for years. I used it to catalog my 70+ long box collection and this app made it easy to do! They consistently make updates focusing on even more ease of use and functionality that helps me as a comic book collector!

I love this app. The design is well-thought out, updated don’t break anything and it keeps my collection organized exactly how I want it. It’s not super expensive either - I highly recommend it to every comic collector. I love the bar code and cover scanning especially, plus it’s also easy to edit entries too. An absolute A+ gem of an app!!

I’ve been using CLZ for years now and love. Keeping track of over 12,000 comic is easy. I have it on iPad and iPhone and can sync between them quickly.

Amazing software to keep track of your comic collection. Huge archive of old and new, mainstream and obscure comics.
