This app is completely amazing
I have to catalog over 4,000 books. I set up a stand for my phone.. got about 2k cataloged in one day.. I really love the interface and the automatic prompt for variant covers. I highly recommend this app for anyone who wants to catalog their collection. — Jason Kaluzny on CLZ Comics

A Quick Review
Watched a video on YouTube, guy recommended, tried the trial, day one paid the money for annual payment. I have spent the last 48hours, barcode scanning my collection, it has been strangely addictive, app is great, no crashes, no slowness it works really well. I am still working out all the different aspects to the app, so far statistics is the best review of what I have. Finally a reliable app for my catalogue. Thanks CLZ team. — vivaldi123 on CLZ Comics

Everything I wanted
Everything I wanted, there are a couple little things and not sure where they are getting the info about the worth of some comics but as far as cataloging and organizing, it's the exact app I was looking for! Keep on killing it CLZ!! — Andrew Lauterborn on CLZ Comics

So easy to use and a very responsive help desk
Just finished my trial period and purchased the yearly membership. Tremendous value!
New to CLZ, I read about this app online and saw it reviewed in a YouTube video. I have a large collection that I have never fully inventoried and I’ve had to use multiple sources for cataloging and Value determination. I initially signed up for their desktop trial which was very functional but since I use my phone more frequently, I was having to sign in through Safari to access the program and my collection. I realized that I was probably better off with their phone app. I had a couple correspondences with their helpdesk ( Big call out to Alwin!!) to try and understand which platform would be better for me and if I could still access my inventory that I had placed in desktop program during my free trial if I now switched to the phone app. It turns out that since everything is stored in the cloud it can be retrieved by either program. The transition was seamless. Near immediate syncing.
I emailed them three times with questions and I received a response within five minutes of each request to their support desk. Great service and for only $15 a year of membership, one of the best purchases I’ve made.
Absolutely recommend this program. So simple and intuitive. — trashcan975 on CLZ Comics

Fun and easy
When first collecting comics, I could keep a mental catalog of my collection by remembering the covers. As my collection grew and variant covers became common, I had to start cataloging my acquisitions. First in an Excel spreadsheet, then an Access database, which migrated to an online SQL database; but the work of cataloging was arduous and time consuming. CLZ has the tools that make keeping track of my collection fun and easy. The mobile app has allowed me to scan over a 1000 books a day. — Spider Bob on CLZ Comics

Quick and easy service
I’ve been waiting for 30 years to get back into cataloging what I have. And I realized that I had over 20,000 comics and was drowning moving them from spot to spot. With this app and the simplicity of the way it works it’s the perfect comic book look up tool you would ever need. Thanks CLZ... — Helmut-CMG on CLZ Comics

A nerdgasm for comics and organization!
I am OBSESSED with your app. I have been looking for a way to catalog my collection, add cover images and we'll everything your app provides. Since we all have time on our hands it seemed like a good idea to go through my stuff but was kinda putting it off from the dread of gettint all the info I wanted. (Cover images, grading, details, variants, organization, etc.) I did some searches and found your app and it rocked my nerd world lol. I've been telling people about it and I've only used it a few days!
I'm about halfway through documenting my collection then go back and do some more deep dive on grading and adding more info but thank you for creating such an amazing tool! It's helped me organize but also realized variants I didn't know about that I can look for to add to my collection. Utilizing your app has really resparked my joy of collecting. If you ever need a poster child to share the love of your app then look no further!
Kudos and thank you! — k3llygp on CLZ Comics

A great app for keeping any eye on your collection
Very good for any collector. I havent added my entire collection as i cant be bothered to scan old covers that the app cant find but I have managed to catalogue nearly 3000 comics very easily indeed. This review has been edited and updated after using the app for over a year and I am very pleased with it. — Mark Mason on CLZ Comics

Amazing App!!!
This app is a dream come true. It’s fast and easy to use. You can catalog your comics anyway you choose . There are multiple options for updating your list. I was able to catalog a huge collection in an amazingly short time. I have my entire collection and wish list at my fingertips. On the rare occasion that I’ve contacted customer service with a question, I got a fast response. I would (and do!) recommend this app to any and all collectors. — collectormike on CLZ Comics
