First of all keep up the great work. You are all doing a great job.
The comics I've added to my account are just the beginning, I'm hoping that once my "Man Cave" is functioning, I'll add my whole collection!
As an older collector :) you have made it so easy for me to catalogue my comic collection, I cannot wait to put my whole collection on the site. Might take a while though!

Great App for Comic Book Collectors
Don’t let the reviews from people that didn’t read the details during the app update dissuade you from getting it.
Though I’m grandfathered in the subscription price is still hardly anything if you are even a semi-serious collector (it’s the cost of a comic or two). I don’t really need the slabbed pricing from GoCollect, but I’m still tempted to try it out for a year. I’m still floored by the people grandfathered in and complaining about the new subscription cost *shrug*.
Anyway, I have roughly 1,500 comics catalogued, and using stuff like the Wishlist when I’m checking out thrift shops or garage sales makes this hobby much easier.
Try it out for a month. You’ll see, and then will upgrade for the year :-) — TaylonHalfElf on CLZ Comics

Simply the best app for comic collectors!
Got everything you need and then some. Totally worth the money and can't compare it to other catalogue solutions. Been using it for years and have no complains. They keep making it better and better! — Dimitris Papastergiou on CLZ Comics

The app is amazing!!!!
The time it has saved me, is just ridiculous! And the way it catalogues is awesome, where it auto sorts alphabetically, but also tells me which numbers in a series I have, LOVE IT!
I don't have any questions just yet, but I do have 3 more comic book boxes to add, so I'll keep your email addy close, just in case! — Sunette Desousa on CLZ Comics

Amazing app
This app has made collecting so much easier. By having my entire collection catalogued I no longer need to guess what I am missing or what cover I had for a given issue. The scanner makes adding new issues each week simple! — Getthis870 on CLZ Comics

Makes comic cataloging a breeze
People rating this app one star for the implementation of a subscription model have no idea what it costs in both time and money to maintain an application with a database such as this. If you dont like that they give you a bunch of cool features to make cataloging your collection easy, and for a fairly reasonable price I might add, then go back to spreadsheets. CLZ Comics makes comic cataloging a breeze. Especially with the barcode scanning tool. — Dillan Pruett on CLZ Comics

Great app, even better service!
I have over 1200 books on my collection and this app makes it easy for cataloging when out on pursuit for the next issue to complete a volume, series, and run! I made a critical error and almost wiped out my library and contacted support that gave me expert help and resolved my issue quick! This app is a must for anyone who collects! — xJMOx on CLZ Comics

An intuitive & comprehensive app
This is superb as a standalone app but sublime as part of an excellently well thought through ecosystem. Adding comics via barcode or series look up is intuitive. It provides endless possibilities in how to view what you have & what’s on your wish list, brilliant when browsing through back issues & needing a quick check of exactly which issue you’re missing.
It keeps getting better with each release, the most recent bringing the addition of Current Value which gets you thinking ‘Really, how much?’
One feature I particularly appreciate, having lost a previous db of my collection to a crashed computer, is the cloud back up so that can never happen again.
Their customer service is very friendly & responsive. Both for proving help & support when required to promptly investigating & fixing bugs. I also use the desktop program which is great if you want to make mass updates or need other more complex functionality. The app & the desktop work together seamlessly so that you can use each to their strengths. The subscription may be off-putting but I feel it offers great value for money.
If I had one caveat it’s that their Core db is a little light on UK titles, but they provide the functionality to fill gaps in their db.
In general it’s just an intuitive & comprehensive app for cataloging your comic collection with the convenience of always having it to hand for a quick double check. — Hatter42 on CLZ Comics

Great App!!
Found this today and I just have to say not manually cataloging my comic collection anymore is a huge relief. On of my favorite apps. — Cmihalko86 on CLZ Comics

Awesome app from very responsive developers!
This app is great for cataloging your collection. It’s super customizable with various sorting options, fields, etc. The developer is always adding improvements as well. Plus, when you ask a question or make a suggestion, they are always friendly and responsive to the customers opinions. I highly recommend this app, as well as the movies and books versions of CLZ! All are well worth the the investment! — UNSTBLmolecules on CLZ Comics

Great tool!
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! — Tigger CVN-69 on CLZ Comics

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
