Amazing App
I have used this app to catalog my movies since I started collecting. Many features to make it easy to add to the collection, to sort by, and even the joy of a random movies to watch. I have now downloaded the gaming app version and know it will be the same.
Support was awesome when I emailed about possible bundle deals for both apps and they directed me right to the exact spot to bundle the two and others if wanted. I would suggest this app for anyone looking for a good catalog app.

Best comic app
I absolutely love this app. I’ve had it over two years and it’s amazing. I can keep track of my massive collection and sort through it in numerous ways. The best part is how responsive their team is for support issues. Whether you contact them on Facebook, or through their forum support, they’re just so quick to respond. The savings alone on not buying duplicates makes it absolutely worth the annual fee.

Latest CLZ news


Another week, another NCBD. It’s no surprise here, that Absolute Batman #19 is the biggest book this week (as can be seen in our Most Wanted on Monday). No less than 54 different covers for this issue! Absolute craziness? Our content managers might even have to be send to Arkham Asylum after adding this many into Core. Don’t think we’re done yet. Image releasing their new series: Fireborn. A bit of a smaller week for Marvel… Here are a few books that were handpicked by our content managers:

Radiant Black #41 Are you caught up with this series? I sure am! Horizon is Chicago’s hero. Radiant Black needs Shift’s help to sneak into a lab that’s withholding secrets. Will they succeed?

Absolute Batman #19. This issue brings us the introduction of Slade Wilson, Scarecrow and the Robins within the Absolute universe. This should definitely be a solid after we know what were getting next issue.

Cheers, mate! After a bit of waiting, we’re back with a new issue of Redcoat #17. This should be a nice set up for what’s to come. I’m especially fond the Kyle Hotz cover!

All comics releasing this week can be found in the NCBD tab in your add comics screen. All new releases have been carefully cleaned up, with lots of info added! Be sure to check them out in the app. Either when you hit your comic shop or, when back home adding your stack you’ve just come home with!

Happy reading!

v10.8.2: Bugfixes

Apr 13, 2026

Fixed:

  • Keyboard would sometimes disappear after typing one letter in the search box above the series folders
  • A crash when tapping a comic in the [NONE] folder
  • The “downloading images” bar would sometimes show even if no images were downloading
  • Comic details could sometimes fall under the bottom bar

Fixed:

  • Converting/Optimizing Database process was slow/crashing for some users. We have now fixed this and made the database conversion much faster
  • Sync with CLZ Cloud: The progress bar for images didn’t count the images that had to be downloaded correctly

A little bit of fun news today: We were thrilled to hear CLZ Movies mentioned by actor and playwright Tracy Letts on the latest episode of Blank Check with Griffin & David called The Year of Living Dangerously with Tracy Letts.

Tracy talks about owning movies on disc, so it’s especially nice to hear that he uses CLZ Movies to keep his collection neatly organized!

Tip: You can listen to The Year of Living Dangerously with Tracy Letts right here.

Or check out Blank Check with Griffin & David on your favorite Podcast player app!


New comics! Invincible, The Boys, Daredevil and Darth Maul Shadow Lord and NCBD. We sure are eating good these days. Here are a few books that were hand picked by our content managers:

Final issue…Power Rangers Prime #16. Rangers vs the Legion Ravager. Going to be the last PR we get for a little bit, they’ll be back in May though!

Cover Girl, Jinx, and Dawn are running out of time to complete a deadly mission. Let’s see what the Blue Ninja’s have in store for them in: G.I. Joe: A Real American Hero #327C. I’ll definitely be picking up the Steve Beach variant.

DC’s. newest Next Level title has arrived: The Fury of Firestorm #1. Firestorm has turned buildings to sand and people to glass with no remorse and no warning. But what exactly provoked Ronnie Raymond to commit this heinous act, and can anyone contain the fury that is Firestorm?
