Latest software updates

I have over 15,000 comics and needed a good electronic tool to catalog and to help evaluate the value of my collection. Between the scanner and the online database, it only took me 4 months to get my collection loaded! Now, with new value tool, I can get a good baseline sense of comics have value, hence which ones to invest in slabbing.
In short, a GREAT tool, and the CLZ folks are extremely responsive and helpful to any questions you might have making the app do what you need it to do!

Great App and Great Support Service!
I’ve tried a few different cataloging apps for my comics and none have ever come close as CLZ does for what I’ve looked for. Cataloging is my collection is so easy by just scanning the barcode. When unable to scan a barcode, searching isn’t difficult at all. It’s organized so many different ways to sort through which is awesome. Having it on my phone is great too as I used to buy a bunch of duplicates before. Now I can check my collection from the app so I don’t buy the same stuff I already have (and just haven’t read yet, haha!)
Another very important factor is their customer service. I had to contact their support team with my account and my database in the Cloud. Having the cloud is very helpful but when I couldn’t fix a mistake I made with my accounts they were very responsive, patient and helpful. The update on their app is awesome too! — Rheannesm on CLZ Comics

Best comic cataloging app out there
The number of features, syncing across devices and layout make this the best app for cataloging your comic collection. I’ve been using it for almost 10 years between the iOS and Mac versions and can’t say enough good things about it. — Daishi00 on CLZ Comics

It’s what you’ve been waiting for
I wanted a way to organize and catalog my old comics and this app delivers. It is really easy to add your comics and the fact that the app has all the cover art too makes even more user friendly. Seeing my collection grow as I added individual comics and series has been strangely satisfying. The process of going through things I haven’t seen in years has been a nice flashback. If you have comics I highly recommend this app. The cloud sync is awesome and there’s an upcoming feature where they’re going to automatically give you the ‘slabbed and graded’ prices of comics on your list. (If you have a great comic or think you do, look that up.)
I can’t wait! Thanks for making this app!

Edit: I recently was experiencing an issue with the app. It turned out to be completely on my end (internet service issue) but I was able to get help quickly and the person helping me was knowledgeable and friendly. — tatovive on CLZ Comics

Fantastic App!
I discovered this app years ago and have loved it since the beginning. I always wanted to catalog my comic book collection, but could never find a great way to do it. The CLZ app made it pretty easy. Plus, it allows for a few features to keep notes and personalize a few things with regards to my collection too. The people behind the app have done a great job keeping it current. Honestly, as a collector this app has become an invaluable took for me. To anyone considering this purchase, you won't regret it. Have a great day! — swasson1967 on CLZ Comics

Essential app for any comic book collector!
This app is absolutely essential for any comic book collector! I started using it about a year ago, and it’s become my favorite app. In addition to cataloging your entire collection, it’s very helpful when you want to know how many issues are in a particular run, so you can see if it’s worth collecting. It’s amazing! The app is incredibly easy to use, I highly recommend it for even the casual collector. For hardcore collectors like me, this app is a must! — Philly fan in SoCal on CLZ Comics

Great customer service!
CLZ Comics is a terrific app! It’s a great way to keep a catalog of my comic collection. It’s intuitive, easy to use and has a great database of comics. When it doesn’t have a comic already in its system, as was the case with some comics that I bought at SDCC, a simple email to customer service promptly fixed that. The only thing I would consider adding is a way to link up with Overstreet or Comics Price Guide to ascertain the value of your collection by selecting approximate grades for each book. Other than that, the app is incredible and I’d recommend it to anyone! Thanks for everything CLZ! — BuckeyeWriter23 on CLZ Comics

Easy to use
Easy to find and catalog my comics. Far easier than other similar apps I have tried. Was worried about spending the money but it's worth it if you need to catalog lots of comics. — Soy El Mariachi on CLZ Comics

One Very Happy Customer
I have found the Holy grail of comic book collecting. I have tried so many different ways to organize my collection in the past. That I had just about given up on ever finding any decent program or application that would truly work. I had settled for doing a hand written Notebook. So I want to give my overwhelming gratitude to you and all who were involved in creating this fantastic application. I have only had it for one day and in less than 30 minutes I have catalog over 60 of my books. even though I am just learning how it works. So Anyone that is reading this that has been looking you need not look Any further you have found it. — TtcSsk on CLZ Comics

Only App To Use
I’ve been using the comic collector for about 7 years. It’s fantastic to say the least. Catalogs all my comics and the want list is very useful when out buying books or cons. Very user friendly and the only app you’ll need. — Madoxswarriors on CLZ Comics

Cataloging with CLZ
5 yrs ago this was my entire collection, after proper bagging and boarding, I started cataloging with CLZ. I think I was around 1500 then. I'm jus a bit over 4k now, switching to short boxes and couldn't imagine not using CLZ.
Even tho I still seem to buy the occasional duplicate... lol — Chris Porter (USA) on Comic Collector

! couldn't be happier!!
Tried a different app to catalog my comics and enjoyed it till it stopped working. A friend suggested I try CLZ Comics and I am so glad I did ! adding comics is a breeze plus to see all the different variants is amazing ! plus to be able to see upcoming issues of my favorite comics is awesome. — Steven Cunningham on CLZ Comics

Keep up the great work!
Thank you so much for explaining how to find additional titles in our already exploding collection! We have taken over 15 plus long boxes of comics out of storage and we are desperately trying to catalog them. It is completely daunting and we almost want to give up... until our local comic store told us to use CLZ.
A fellow comic collector told us of other competing comic apps Which also catalog but simply does not have the intuitive ease that CLZ Core has.
But again we have to say you reaching out to us on a simple free-“trial app” to ask if we had any questions has closed this deal! There is a learning curve to “cataloging” and no doubt made easier with you explaining how to find all the titles!
Thank you for making this cataloging process so painless! We estimate over 1200 comics! Today we are pressing “purchase” and joining the CLZ Core family!
Once again thank you for your amazing customer service and for helping all of us collectors to manage what we love...Comic Collecting! — Gary Chan (Canada) on CLZ Comics

I love it
If I had this app back then as opposed to now I'd have sooooo much more comics with money. This app makes it way easier to catalogue what I have and keep track. I love it! Now, if this app could find a way to price said comics in the catalogue..... — Sevell Robinson on CLZ Comics

My collection available anytime
Just started using this and I already can tell it's going to be awesome to have my collection available anytime. The barcode scanner makes it very easy to catalogue your collection. I've been using this app for a while now and I think it's a must need for any comic book collector. — 74 SCREWGUN on CLZ Comics

Signed up for the $15. Haven't had an issues so far. Only thing I'd like to see is if they could add a section or option to be able to catalog my graded issues. — Armando Hicks on CLZ Comics
