It works now!
My film and tv library is close to 1000 and my books nearly 300. I visit charity shops regularly and without the help of these 4 apps I would be buying multiples all the time.
I have many awesome things to say about your product!
Latest CLZ news

We’re slowly recovering from the SDCC craze! Luckily, we have a somewhat quieter week ahead, with around 395 new variants releasing. After last week’s record-breaking numbers, the content team can finally catch its breath.
Let’s take a look at some of the releases hitting shelves this week. First up is Queen in Black #1, written by Al Ewing with artwork by Iban Coello. This new Marvel event throws Hela and Knull into a cosmic clash, with Earth and its heroes caught right in the middle. We are already on the lookout for those blind bag variants!
Our second highlight is X-Men, Vol. 6 #34, written by Jed MacKay. This issue puts Cain Marko (Juggernaut) front and center. After a lifetime spent as a bully, criminal, and supervillain, Cain is now an X-Man. But can the Juggernaut stay a hero?
Last, we take a look at Alice Forever After #5, the final issue of Dan Panosian’s dark reimagining of Alice in Wonderland. This tale is finally coming to it’s ends, and we can’t wait to see how it happens!
All comics releasing this week can be found in the NCBD tab on your Add Comics screen. Every new release has been carefully cleaned up, with lots of extra information added, so be sure to check them out in the app—whether you’re at your local comic shop or back home adding the stack you just picked up!
Happy reading!

This is it, the big v11.0 update for your CLZ Comics app. About a week later than planned, because our friends at Apple sure took their time reviewing our update 🙂 Oh well, it’s here now!
Version 11 is a huge step forward in the customizability of the app. And I am not talking about tweaking the look and feel here, like layout, colors, fonts, etc… No… this time we are giving you the ability to actually customize the database itself, with your own “Custom Fields“!
The Custom Fields feature will let you create your own data fields, to catalog any information for which the app does not have a built-in field. You can create text fields, number fields, date fields, Yes/No toggles, pick list fields and much more.
All fields you create can be edited on a special Custom Fields tab of the Edit Comic screen. The entered data will nicely appear in a special section on the comic details page. And of course, you will be able to use the fields like any built-in fields, that is, sort on them, use pick list, date and toggle fields as folders, search your text fields, etc..

These top-10s are created by you all, the users of the CLZ app and software, as they’re based on how often these comics already appear on your wish lists in the CLZ Cloud, even before release!

Our biggest NCBD yet! This week sees the release of 1,235 new comics. It’s been a busy week over here for the content team!
This crazy number, of course, has everything to do with San Diego Comic-Con, which starts tomorrow. We are now up to 664 SDCC exclusives, and that number is still climbing. On top of that, there are 99 regular store exclusive variants releasing, bringing our total exclusive count to 763 exclusives.
Let’s not forget the regular releases hitting shelves this week. Out today is Gambit: Wanted #1, written by Chris Claremont, so you won’t want to miss it! Also releasing this week is Terminal #1, which looks to be Image Comics’ take on the X-Men. We can’t wait to see what it’s all about.
Last, we take a look at Teenage Mutant Ninja Turtles #20, which also marks the series’ legacy numbering issue #300! We had our hands full with this one, as there are 90 different variants releasing for this milestone issue.

Happy reading!
