Comic Book Organizer Software

I have used CLZ for years now. The power the app gives me over my collection makes organizing a breeze and honestly collecting even more fun.

I don’t write reviews on apps. Actually I don’t write reviews on anything. However. If you are reading this and thinking about organizing you collection then read on.
I had over 20,000 books sitting in my basement. My wife said “get rid of them or I’m calling my attorney” (well kinda), they had to go. I opened a few long boxes, checked on book one to see what they were worth and was surprised to find the books were actually worth real money. I post a couple on eBay , and they sold.
Ok, so how do I get rid of all these books? I needed a way to organize then. After a little research I found CLZ. At first it was tedious entering the books. As a early user, the app still had ease of use issues. However, the incredible staff continued to improve the application. It is now scary how easy it is to catalog, organize, track, and value your books.
If you have a collection that needs to be organized this is THE app. Truly a great tool. And, they keep improving. Yes the price has gone up a little but it’s worth every cent. Love the scanning, and sales tracking. Yes, I still have tons of books, but the wife has taken her attorney off speed dial!

The scanner/cover picture function makes running through boxes of comics a breeze!
The subscription is more than worth the peace of mind of knowing exactly what you got.
Being able to organize them into different folders and types “collection, for sale, wishlist” etc. is honestly so smooth!
If you’re tired of writing things out or filling out some god awful spreadsheet for your collection this is really your only option.
Funny thing is, I’ve barely scratched the surface of functionality!

Got my whole collection logged and organized with price tracking on all of them. It even helped me find out a couple of books to sell online. super easy to scan all my comics in (i recommend barcode scanning as it's quicker) and the cover scanning gives you tons of options to choose from to make sure you're logging the correct book.

Fantastic app for comic book collecting and organizing!

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

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’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.

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 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.

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!!

Excellent customer service and a great app for collecting, I do wish there was a way to read them digitally on here but I understand that is hard to do. I would recommend this app to anyone else wanting to build their collection or just organizing their current one.

It was a joy cataloguing my comic collection a few years ago, and discovering CLZ blew my mind. Sorting and categoric features are superb, integration with CovrPrice for pricing is seamless, and it’s just fun to use the app daily to peruse what’s in my collection.
Developer support is awesome and responsive, they have a dedicated FB group to field user questions and concerns. I always recommend this app to collectors asking for the best way to organize their chaos.

This app is amazing! Been collecting for a while and organizing has always been challenging…this app made it super simple and made collecting more exciting..customer support was also quick to respond when I had questions about the app..I highly recommend this for collectors!!!

Fantastic comic organizer.

The best way I've found to organize my collection. I use their other apps well.

Best app for organizing your books. Vast database and customer service is 2nd to none.

I was able to quickly add quite a large collection of single comics and trades. 3 different methods for entering: barcode, photo of cover, or typing in series. Very flexible tools to organize your collection. Had to use the support a couple of times and they were quick to respond, attentive and personable! Highly recommended!

The cover scan feature makes adding variants, newsstand/direct, and virgin covers nearly effortless. The Covrprice integration is clean, giving quick value checks at LCS or conventions. Rich meta fields and organized information make managing a collection easy, with intuitive filters and sorting. Cost competitive with ComicBase, it scales to your needs while keeping your collection precise and accessible.

This is the ultimate organizational tool. Already saved me from misremembering and buying a duplicate comic issue.

I tried other apps. This one was the easiest to get started with, and has the most options for describing and cataloging your collection. Subscription fee is very reasonable in my opinion, and you can optionally add a subscription to the Covrprice pricing guide with a discount if you sign up for both.
If you have a large collection like I did, from back in the 90's and you want it organized fast, this is the app you want. Also, they have been super helpful and quick to respond to any questions.

Incredible tool to organize comic books!!

The coolest comic book organizer, it does offer a ton of cool options, and settings just takes a little time to navigate everything! It's definitely worth using to organize comics.

Awesome tool for organizing comics.

Hands down the best comicbook organizer on the market. Well worth every penny!!

My "go to" for organizing my comics AND preventing me from buying duplicates.

I can finally organize my small-ish collection.

Just got back into comics and it makes it so easy to organize and keep track of what I have and need.

Great app, helps so much with organizing and tracking, scan cover is so helpful for adding and checking values. With it connected to CVRPrice it is even better.

This app is perfect for keeping my comic collection organized. I have separate lists for my graded and ungraded comics plus a list for comics I want to buy. Plus the support has been fantastic. I highly recommend it.
