Robust and simple at a great price
Love this app. Inherited a 1300 comic collection and needed to know what I had. After searching for awhile, found CLZ. Without a deep knowledge of comics, I was able to quickly and easily understand how the app works, catalog the whole collection and manage it to my satisfaction. 95% of the comics were immediately found either using the series or barcode search, and I was quickly able to get a handle on the contents and ballpark value of the collection. Plus, it’s a great deal. Support has been very responsive and provided great answers when I’ve had questions. Only one small item that could be improved - it’s confusing that there are multiple cloud solutions that go with this app (free and subscription), would be clearer if that were streamlined or explained better.
Regardless, I am very satisfied with this app. — Anonsocal on CLZ Comics

Satisfies my OCD
I’ve been keeping track of my collection in a Google spreadsheet like a FOOL. I wish I had found this app a lot earlier because it is perfect. I spent an entire Sunday cataloging and fine-tuning my collection. The customization options here are the highlight. I love being able to have a display name for a series that differs from a sorting description. Highly recommended for anyone with a moderate to large collection. — OThatMatt on CLZ Comics

How is this app so awesome?
I really don’t know if any other app/offering that is so great for cataloguing items as CLZ. I currently use the Comics and Movies apps in addition to using the online version, and even a desktop software for my Mac. The syncing between all of those is fantastic. And this developer is always adding enhancements and new features, as opposed to some who just push out improvements a couple times a year or something. A huge thank you to Alwin and the team who work so hard to make this so great. — TravyBaby on CLZ Comics

The best there is for comic book collecting cataloging
I have a very vast collection of comic books as I started collecting in 1984. I have been thinking about how to figure out everything I have? I searched online and most apps that offer this service received poor reviews. I kept looking and found CLZ! I could not be happier with how easy it is to catalog my collection. There iz s reason they have a high review as their app delivers! I work as a librarian so I know a thing or two about cataloging and organization and CLZ does it the best! — FLUX BOY on CLZ Comics

Love it
Just what I needed. Was planning to create my own catalogue of my comic collection. It would have taken months. Should have it all done, in a couple of weeks. Also great that I can view it online. — Robert Arnstrong on CLZ Comics

If you collect comics then this app is a necessity. 1st being able to catalog all your comics is needed. The barcode scanner makes it easy to simply scan each comic into your inventory. Then you are able to access it anywhere you are. On top of that you can track the values of your comics by putting a grade in. — Bryan Hills on CLZ Comics

Pretty much what it says on the box
I’m still learning the ropes but it is a great way to have a digital catalogue of my comics. It’s especially great for modern comics because you just scan the barcode and it automatically organizes it. Really couldn’t ask for a better app, and the price is really reasonable. — Jimmy Alleyn on CLZ Comics

I love the app! What a wonderful tool. I never would have been able to start cataloging my collection (thousands of comics) without it. Thank you for creating such a truly helpful app. I've only just begun, but with the app and the cloud-based syncing feature, I will be able to create a complete inventory that can later be exported and shared online. — Porter Huddleston on CLZ Comics

Still learning
While I'm still learning all the ins and outs of using the app, it's obviously a very good way to catalog my collection. I definitely like the ways of inputting the information as well as displaying that information. — Spider doc on CLZ Comics

Meticulous organization
I can never say enough good things about my Comic Collector Desktop, CLZ Mobile and the Comic Connect Web. I use and subscribe to all of them.
I started off with building my own spreadsheets for my collections. When I first tried the desktop version out about 6 or so years ago, my jaw dropped to the floor. The capabilities, the included details and the fact that we are able to submit requests to update, modify or even add to the core is unlike anything else out there.
My need for meticulous organization and cataloging my collection has been more than satisfied with these products. The amounts of details I can have and add to for a single issue is way beyond what I was willing to do in a spreadsheet.
Again, I can not say enough positive things about these guys. My only complaint is that they don't have a satellite office in San Antonio, TX for me to apply for a job at. However, I don't know what I would be able to bring to the table, because these guys already do it all!
Thanks a million for saving me thousands of hours not having to keep cataloging my collection in spreadsheets!!! — Robert Hurley-Welch (USA) on Comic Collector

Best app for comic book cataloguing, very responsive support
I have used CLZ Comics for almost a year now and the convenience it provides for cataloguing and updating a large comic book collection is unmatched. I particularly like the connection to GoCollect for updating values and the instant statistics it give you about the collection. App support is very responsive and they have always addressed all my concerns to my satisfaction. — shaun2ralde on CLZ Comics
