Love this app so much!
Excellent way to track your collection and want lists! Great value compared to on line programs. Update - just went with the premium version which in an absolute steal at $14.99 a year! Highly recommend for any comic collector, you won't find a better way to track, inventory and keep updated on comics. — Brian Tobin 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

Easy to use and extremely helpful
This is, by far, the best comic inventory software! It is constantly being updated making it even easier to use, and with new features. At a glance, I can see the issues I need to complete a series. Or I can dive deeper to find out what my graded comics are worth, and what I paid for them. The app itself is super fast and I love the cloud backup (for when you change phones). This app is a must for all comic book collectors! — Andrew Seiser on CLZ Comics

Excellent App!
I didn't know how I was going to manage to keep an inventory of my comics I have almost 1,500. Or how I was even going to get an idea of how much my collection would be worth. I was looking for an inventory logging app and I saw this. What a relief someone thought to make this. It has almost every comic I've ever entered in their database with detailed info on most. I can scan them with my phone. Easy, easy, I'm super happy with this app worth every cent. — earth belowskyabove on CLZ Comics

Comics inventory
Great way to quickly manage my comics inventory. Just started using it and I'm loving the bar-code scanner. It scans right though the bag and recognizes comics dating back to the Bronze Age. — Spider Bob on CLZ Comics

Phenomenal app!
It makes everything so easy to do, from cataloging, to getting fair value prices for select comics in my inventory. Very glad I bought and subscribed to this app, worth it! Oh and the cloud feature is a very nice add-on! — Jeremy Reynolds on CLZ Comics

Insanely helpful and smart
I recently dove back into my old comic collection to do an inventory of the over 500 books I had. A buddy suggested that “there must be an app that helps with that”. So after some googling, I found this app. I cannot stress enough how easy and FUN this app makes my collection. I also love the Wishlist feature where I can keep track of books I’m trying to get my hands on.
The Value updater from gotocollect.com is extremely helpful and the impressively high number of filters I can organize my comics by is frankly astounding. Also, scanning by barcode is so so so so helpful. I think of the now 600 plus comics I’ve scanned, I’ve only run in to a barcode that wasn’t recognized like 5-10 times, but was able to find the book by searching by series and issue number.
Highly highly HIGHLY recommend. — NikDeezie on CLZ Comics

Latest upgrade is awesome
If I could marry an app, this would be my pick. This app was the best thing to happen to my comic life since I read my first Batman comic more years ago than I will admit to. I used to track my books in spreadsheets and scribble notes for months until I took the time to update them. Then I found this app and scanning in books and carrying a copy of my inventory in my pocket made trips to my LCS much more enjoyable. I still see people doing it the old schools way with paper and I show them the app. They’ve made improvements over the years.
One thing that was always a pain was the groupings. I have over five hundred series so scrolling through just my Batman books was a pain. They had series groups but to use them effectively, I’d have to manually update thousands of books to put them in the correct series group. I didn’t have that kind of time so I’ve just been dealing with the series list. But this latest release has group editing. I can move all my Superman or Batman comics into a series group through group editing. It seriously takes less than a minute per series. Unbelievable! I actually reached out a few years ago to ask for this and I can’t believe it’s here. I can add my own series groups too like “Batman mini series”. I have total control on groupings now.
The edit screen is a major improvement too. They’ve made improvements to entering a comic too. They’ve updated the values which I’d love to use but I’m not going to take the time to grade my collection. I tried a couple of other apps before I settled on this several years ago and I’m so glad I picked the winner. Thank you to all the developers who took the time to really think these changes through. A lot of times software updates come with a bunch of unnecessary changes to things that already worked. CLZ hit it perfectly. They left all the good stuff and made improvements where needed.
Great job. Thank you! — Apock on CLZ Comics

CLZ Comic App is AMAZING
Hello all comic brothers and sisters. This IS the app your looking for. This truly goes to 11. The ease of use, batch listing, UPC scanning for easy and fast updating of your collection. Worth every penny. Take your pocket inventory with you everywhere for those times you think you found the one variant or missing edition but are not 100% sure. BAM!!!! You can quickly look and be sure. Then grab it and run up to the counter and buy it quickly and leave the store with a huge Joker smile knowing you just found that elusive comic you have been looking for, forever. I keep another group for my big bro needs to help with his collection as well.
Now stop reading this and go buy it. You will wonder why you waited so long to get it or to even to find such a great app. — AnkenyLetGo (USA) on CLZ Comics

I love it
This app is amazing. I’ve tried to keep my items catalogued on excel, but who wants to log on to a computer to update every purchase or sale. And y’all about the convenience of having your entire inventory with you when hunting. I am so happy I found this app. And the tech support has been outstanding. There were 3 things I wondered if were possible, 1 email, and a reply was in my inbox in the morning with instructions. 10 stars worthy. — jperez021 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

April 09, 2020
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

Great tool for a collector
If you’re like me you sometimes find yourself at a random box of comics finding some cool stuff and then accidentally buying a book you already own. This app helped me out quite a bit and I finally have a nice inventory of all the comics I own. It’s quick and easy to use and so worth the price. — bearhart439 on CLZ Comics

Great for tracking comic
A friend recommended this app to me and I’m loving it. From the quick setup to using the phones’s camera as a barcode reader, this app just makes getting your comics inventoried and easily organized simple. Other features include allowing others to see your inventory via an external url and there are lots of sorting and filtering options. My favorite is the statistics around the value of your comics. As a comic collector for 35 years I finally have an easy inventory tool. Thanks , CLZ!

Pros : inexpensive app
Friends able to view inventory
Syncing function for backups
Export options
Auto comic value lookups via gocollect.com
Customer service response and open to suggestions for future app features — kennyscomics on CLZ Comics

The app is amazing
I find it to be very user friendly. I added roughly a fifth of my collection in just a few hours totaling 1100 + books. I was even able to find in your system really obscure books I was sure I wouldn't find. I look forward to adding even more today. Thank you for your wonderful app that is allowing me to easily inventory my collection in detail. — Michael Guyton on CLZ Comics

Inventory software
I love your inventory software and can't imagine going without it now that I have it. — L.E. Gill on CLZ Comics
March 06, 2020
This is just a friendly recommendation for you collectors out there. I am way impressed with CLZ Comics inventory app.
1st - you can scan the barcode on your newsstand editions and it automatically loads the comic to your inventory.
2nd if it’s a direct edition you can search the database and add the issues. On many of the comics it will give you the going price based on GoCollect comic book prices based on how you grade your comic. If it has no price you can assign and lock the price so when you “auto update” comic prices it will not remove the value you assign and give it a zero value.
Most of my comics I buy from mycomicshop so I value my comics based on what I paid for it and the comics from them are graded by trained in house graders.
You can create wish list of comics you need to plug holes. And the best part - it’s all on your phone so when you’re at a con or comic shop you always have access to your inventory. I just can’t rave enough - this is the very best $1.50 a month I have ever spent.
You can also download csv excel spreadsheets of your inventory for hard copy. I’m so Impressed I am going to upgrade to the CZL comic app to the app + comic collect software for my Mac for $40.00 per year.
If you have a large collection- this is the best money you will ever spend to organize it and value it. — MichaelBSmith63 on CLZ Comics
