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

Great app
App is great for cataloging, especially the ease of using the scanner. This app would get 5 stars if it added estimated worth of books. — nuzzbom on CLZ Comics

My collection under control and in numeric order
I've been using CLZ for my comics for 3 or 4 years now and had been doing things manually before that. My collection currently exceeds 18,000 books and I've been collecting for decades.
When I started collecting, I kept a hand written ledger of my books so I wouldn't spend my hard earned cash on duplicates. When Lotus 123 came on in '83 (does anyone actually remember Lotus 123?), I procured a copy and transferred my entire collection to a spreadsheet. Awesome. My first actual backup, besides my hand written book, was to a 5.25" disk.
After Lotus was crushed by Microsoft, everything had to go to Excel. I believe that most everyone has a horror story regarding hardware and mine was a crashed hard drive in '96 that ate my data and left me with just a 3.5" disk that contained the backup of my comic collection. Needless to say, the disk turned out to have been corrupted at some point and I was back to ground zero.
With all of the writing and keyboarding over the years, I'm pretty sure I'm patient #0 for Carpel Tunnel Syndrome. It was then I decided the Comic Books gods did not want me to know what I had in my collection so that Marvel, DC, Charlton, and the rest could get more of my hard earned cash since I'd likely be buying duplicates at one point or another.
It wasn't until I found CLZ 3 or 4 years ago that I started to catalog my collection again. This has done many things:
It uncovered more than 3,000 duplicates (hard earned cash out the window. My ex-wife was angry about that tidbit).
It allowed me to actually get my collection under control and in numeric order in their boxes (currently 170+ short boxes and a couple of long boxes
The initial time of entering them into CLZ was considerable, but necessary. Now when I buy 2 or 300 books at a show, it's so easy to get them into the system.
It allows me to travel to Comic-cons and bring my collection with me so when I'm spending my hard earned dollars, I'm not buying dupes. (something my current wife appreciates)
I finally know exactly what I have and I know it's safe from most any tech disaster that I might have.
Most important in all of this? It provides a safe place for my database. Something I didn't have for 40 years.
I forget what I paid for this program when I bought it, but it's been worth every penny of my hard earned dollars since. — James White (USA) on Comic Collector

CLZ has made my life so easy
I am a 56 year old lifelong comic fan...and still collecting. I have about 15,000 comics and before discovering CLZ I used a looseleaf notebook to add all my comics. Needless to say, this turned into a ripped, and disorganized mess very quickly. Of course, I was only able to catalog the title and the issues that I owned and I could never see the critical data or the comic covers.
I constantly use CLZ, not only for data entry, but to view my lovely collection. I also love the way that CLZ breaks down the stats to my collection and gives me possible value of the collection. The software support and updates are spectacular!! — Scott Farren (USA) on Comic Collector

Amazing app
I started collecting comic books in the early 80s. Mostly Marvel but I branched out to some Image comics and DC in the 90s when Spawn was created. I began liking the darker comic books with more detail in the graphics. I stopped collecting until I got stable then began to board bag and catalog all of my books.
In the process I noticed I had some valuable books such as the first appearance of Thanos and Deadpool. I wanted to get insurance on my books and have a detailed list on a cloud based program to insure I would not lose my collection should something tragic happen. I found CLZ in my search of this app and found it to be easy to navigate, very organized.
I have 4240 comics cataloged and sent to my insurance agency. I then started to use to wish list when I would go to comic shows to quickly pull up books I'm looking for rather than using paper lists that would ultimately end up in the washing machine. Thanks to this great app. — John Miller (USA) on Comic Collector

CLZ is AwesomeSauce
Hi My name is Lance Keeble. I am a Super Collector, as well as a Life Saver, Author, Father and Grand-Father. I have an eclectic taste and a vast collection of all the things I like, which include, Comic Books, Books, Music, and Movies. I also love Action Figures, Toys, Happy Meal Toys and things that fit in categories that are difficult to pin down. CLZ has helped me catalog my vinyl collection that is a combination of my parents, my wife parent and the 2 of us...Our CD's, Tapes, Vinyls and a few 8-Tracks total over 1,350.
My book collection has diminished only because I have donated 75% of my collection but I kept the ones important to me or have been signed. My comics are a lifetime of collecting from since I was a teen. I did at one point collect only number ones, adult, independent and minority drive comics, but I am happy to ay that it is easy to find those types of works now... I am having a ball. I don't spend as much as I used to, but I do still collect when my budget allows. I am on the Social Media site Gemr...Come check me out, I feature CLZ in my posts. Keep up the good work! LOK — Lance Keeble (USA) on Comic Collector

This program is great!
With a good camera/scanner, you can plow through cataloguing your comics. Occasional series issues, with Marvel's random renumbering their series', but it keeps up pretty well! — Ian on CLZ Comics

thank you for creating such a nice product
I don't have a problem or question with your software but I just wanted to thank you for creating such a nice product for cataloging my comics.
I purchased the year long Connect license and have been using it since day one. Now I just need to make more time to enter them all in since I have 1,000+ books in my collection! — Eric Fernandez (USA) on Comic Collector

Thanks a ton CLZ!
By far the best app for cataloging all my comics. I have had no issues and have used it for a few years. Very useful indeed. I recommend this app to every collector I know. — Giant_Robot_Fish on CLZ Comics

I am really enjoying this
It also gives me an excuse to go over my old books. I enjoy the fact that i can add tags, because i get a lot of comics signed at conventions, i can keep track of it. Along with the idea that if i want to meet an artist, i can quickly look through my collection to see if i have any books of theirs. Its really good. My only complaint is that on rare occassions it will give a mixed title with the correct cover or vice versa. And since it does catalog art books, i kinda wish it had an ISBN search as well. But overall, lovely product, paying for it was a simple choice. — Malcolm Earle on CLZ Comics

Solid App— Near Perfect
This app is by far the best collector app on iOS that allows you to create a catalogue of your collection with a vast database of comics. It organizes neatly with a clean design and has a variety of settings including a dark mode! The App provides a ton of details about each issue and has the ability to add wish lists as well. You also have the ability to add personal details about your individual issues such as price you paid, location, owner, etc and has the ability to enter the value manually... ... which is great, however with large collections and the fluctuating nature of comic values makes that less intuitive than I’d like. This is a minor gripe and could hopefully be a feature added to future updates. All around, this is a solid app and worthy of its price tag. P.S. The trial allows up to 100 issues for free which is more than reasonable for one to test out and decide if the app works for them. — Andrew A. Viarruel on CLZ Comics

Couldn't ask for a better app
This is probably the best comic book app I've ever had for collecting...EVER! You really couldn't ask for a better app to be able to allow you to scan multiple comics in to your collection via barcode and keep a collection on you as massive as your own ,if you have a lot of comics that is. I highly recommend this app to anyone and everyone who collects comics and needs some way to catalog and organize their Comics especially when they go out to buy more and want to know how much they need, or what key issues are missing from their collection, or just to check to see if they need anything that they don't have at the in their home collection. This app is definitely a must for any Comic Collector out there! — Rex Ward on CLZ Comics
