Joy to use
Makes cataloguing your collection a lot easier than trying to do it yourself. I finally got the unlimited version of the app and I am thoroughly enjoying it! — Nicholas Ornelas on CLZ Comics

Stop with the duplicates and get organized!
Other reviewers cover this app well. I’ll just say that I love being able to enjoy the art gallery of my comics anywhere I go. That and being able to pull up a clean wish list when shopping for comics!
I just started collecting last year and this was the answer to my growing collection for both cataloging my buys and organizing my wish list. Forget spreadsheets and to shop lists!! And no forgetting what’s in your comic bins! — Customer on CLZ Comics

Great tool
Easy and great tool for cataloging your collection and looking for issues you might be missing. I've had a running list in my phone for years that helps me keep track of which issues I have by number, but isn't much help with variants. This app shows you each and every book you have by cover and allows you to scroll through every cover of every book out there by volume to see what you may be missing. This is an incredible and must have tool if you're a completionist like myself. — A Google user on CLZ Comics

Don’t even try a different app!!!!
This is the only one you will ever need, I use it on my phone to make sure I don’t buy dupes, see what I am missing while in the shops and just to randomly open it up while I am waiting somewhere and scroll through to look at the collection. I use it along with the computer program and easily update everything. I also use the buddy to scan them into the catalog it is super simple.

The only app you need for all of your catalogue needs. — Russell33005 on CLZ Comics

Manage your collection
Awesome app to manage & catalog your entire collection. It also helps you with you Want List too. If you happen to find yourself digging through long boxes and come across an issue or two, you open the app and check out ypur want list right then. — A Google user on CLZ Comics

The easiest app to scan your collection
Literally the easiest app to scan your collection. even if the older barcodes dont catch, it's much easier to look up your comic manually than any other app I've used. this also had a better catalog of comics. It found all my comics whereas other apps I've used couldnt find some comics. this app is amazing! — Leanna Crumpler on CLZ Comics

Great catalogue app
Great catalogue app, easy to add books, and nice detail view. I would like to be able to increase the thumbnail size, it's just a bit too small for my old eyes. — Phil Cady on CLZ Comics

This app is friggin awesome
I started collecting comics when I was a kid, but like most of us stopped as I got older. But The Walking Dead like so many brought me back to my local comic book store and I rediscovered the joy I had in my childhood. In time I had a massive collection and started buying long box after long box. But not really knowing what I have in my boxes. But I didn't want to go create a Microsoft Excel database, and last Saturday while I was picking up a few books a guy at the shop I frequent told me about this app and I downloaded and tried the first 100 and found it extremely easy to catalog what exactly I own.
Now I know what exactly is in my box at all times and have it right on my phone so I can see what issues I'm looking for and avoid buying doubles. Six more long boxes to go!!!
Thanks CLZ. — Horrible915 on CLZ Comics
