Best Comic Collection App
I have tried so many apps and even tried using a self-made spreadsheet and had little to no success. This app does it all. It scans the barcodes perfectly and when it doesn’t know which issue you have you can select your cover from the drop down menu and bam, your issue is added to your collection.
Additionally, I’ve upgraded to the subscription which provides your comic values!

High level of customer service
I wanted to thank you very much for the credit you have issued to me and the clarification of what I should be purchasing in the future. If all companies had the same high level of customer service as Collectorz we would be a lot better off.

I am a fan
I’ve long been a fan of your company’s software and end-user services. Now I’m a fan of the customer-support team, too.

The best software support
I had been using “Music Collector” (PC version) for about 2 years and recently was having some issues when I added new albums to my inventory (I have about 1,500 albums either on CD of Vinyl LP.) I contacted Collectorz.com user support and then heard back from Anthan-John (AJ) for assistance. We must have exchanged emails about 5x (note I am on the East Coast of the USA and Collectorz.com is located in Amsterdam, the Netherlands) and of course there is a 6 hour difference as they are ahead of me. I did not expect to hear from them until the next day. The next day I received a response and each day after I sent additional info to AJ I heard back the next day. AJ suggested I might want to try the internet version of their software “Music Connect.” I gave it a try and then switched to it because it is a lot easier to add an album and they have my inventory on their server. I can also back-up for inventory on my PC, an external drive or export it to a CV file if needed.

I also use their Android version on my Galaxy S20FE 5G so I can check my inventory as I am shopping for an album, so I don’t purchase one I already own.

I also must say that AJ & Alwin Hoogerdijk, owner and founder of Collectorz.com, provide one of the best software support I have had in years. (I have been using computers since 1986). So if you are concerned about support don’t worry they will always have your back and the annual subscription is extremely reasonably priced.

It’s a beautiful, misty day over here as we are nearing the end of October. This week for New Comic Book Day we prepared 222 new issues with 528 releases overall.

DC Comics has reinvented Wonder Woman in the brand new series Absolute Wonder Woman. Be sure to check out issue 1 and prepare for a much darker story.

Image Comics tricks and treats us with several new series, such as Nullhunter, Hack/Slash: Body Bags and The Feeding to name a few, but the one series you might not want to miss is Voices In My Head. A collection of scary tales, written by Eisner Award winner Joe Pruett. This might just be thé perfect comic to read for Halloween!

Finally… lets not forget everyone’s favorite superhero. Tony Stark is back, once again, ready to fight the evil forces of Roxxon and AIM in issue 1 of the new series Iron Man, Vol. 7.

Enjoy!

Starting from the year 2000, our name has been “Collectorz.com” with our website at “www.collectorz.com”. Makes sense, right?

But since the release of our mobile apps, titled CLZ Comics, CLZ Movies, etc.. many users started to refer to us as “CLZ”. So we figured, let’s go with the flow and officially rename the company to just “CLZ”!

So last week we made the big switch. Our company is now called “CLZ” and our website has moved to clz.com. (We have owned the cool CLZ.com 3-letter domain for many years and now we can finally make full use of it!)

But that’s not all. We took this opportunity to make several other big changes:

  • A new company logo and styling for the CLZ brand
  • A complete redesign of the CLZ website, with a fresh and modern styling
  • All CLZ mobile apps have new icons, to fit the CLZ brand and styling
  • Our web-based software, previously called Comic Connect, Movie Connect, etc… , is now simply CLZ Comics Web, CLZ Movies Web
  • Where necessary to make the distinction, we will refer to the mobile apps as “CLZ Books Mobile”, “CLZ Music Mobile” etc…
  • The CLZ Shop has moved from shop.collectorz.com to shop.clz.com.

Holy Wednesday Abbreviations Day, Batman! It’s NCBD again! This week we prepared 244 new issues with 541 releases overall.

Let’s kick off with one of the most obvious new series released this week, Batman and Robin: Year One. In this first issue Bruce and Dick face a mysterious new crime boss called the General. Generally speaking, he should no competition for The Dynamic Duo.
Wanna know who’s also back with a brand-new series? Our favourite shape-shifting superhero: Marvel’s most mysterious mutant Mystique, m’kay. Be sure to check out Mystique, Vol. 2!

And last but not least, Image Comics offers us #25 of the freaky and scary series The Department of Truth. Apparently this issue will answer a few boiling hot questions!

Enjoy!

It “has come to our attention”… that many users did not like the new app icon we introduced in version 9.10, as it resulted in Advice, Apathy, Annoyance, Anger and even Aggression 🙁

And after reading all user comments, we must agree, we indeed messed up there. Sorry !!!
