WOW, I'm totally impressed
This app and web based attachment it absolutely fantastic. The sync between the two is awesome and the scanning is fastest I've ever witnessed. Best buy I've made in a long time, will be switching my payments to yearly before end of the month.

Thank you CLZ Team!
I’ve been a fan and user of the CLZ Comics app for more than 12 years now, and there is no app on my phone more important to me. It is absolutely indispensable now, and there’s no way I could manage even a modest collection like mine without it. Thanks to you and the CLZ team for all the work and care you put into the Comics app. I appreciate it as I’m sure every user does or should.
Knowing how useable and comprehensive the Comics app is led me to subscribe to the Movies, Music, and Books apps this week. Especially as I prepare for a couple of moves in the next year or so, this was a great time to subscribe and keep all my other collections organized and noted where individual books and records are stored for easier retrieval.
I’m not a gamer per se, but I’ll probably join the Games app eventually even if only to keep track of tbe Atari 2600 games I own vs what I am still looking for.
Thanks again to you and the whole team.

I really admire you and your team
It was a sleepless night, early in the morning hours, and I attempted to complete the purchase on my Android. PayPal decided that was the perfect opportunity to mess with me, and it wouldn't allow me to log on, change the password, etc. This morning I used my laptop, which is a much more generous and forgiving device, and all is resolved!
Don't get me wrong, and just for the record, I am not disparaging my smartphone (all hail our wondrous robot overlords)! Appreciate your concern, rapid follow-up, and friendly offer. I really admire you and your team, even the non-robots.
Have a great week ahead!

NCBD!

Fantastic Four / Gargoyles #1 Danger strikes when the super villain Diablo learns stone gargoyles may hold the secret to eternal life… but the Gargoyles aren’t about to let him leech the blood of his own! Fortunately, they’ve got the help of expert Diablo-bashers — the Fantastic Four! Plus: Tony Stark and David Xanatos compare facial hair, Marvel’s own Gargoyle, Isaac Christians, bonds with his new kin, and more! You won’t want to miss this collision of beloved universes!

Save Now #1.Armed with the extraordinary ability to “save” any moment in his life and then go back and relive from that point forward again, world-famous superhero SAVER can rewrite his past, altering his actions time and time again until he gets things right. But with great power, also comes great pain. Cursed with only being able to travel backwards, never forwards, he is burdened by having to spend his relived life in agonizing real time. Travel back 6 days, and he must relive those days in full, aging all the while. After catching a glimpse at the impending apocalypse, Saver dedicates himself to averting global catastrophe, no matter the cost. But no matter how many times or how far back he goes, he can’t find a way to steer the world clear of armageddon. With no hope for the future, Saver retreats to live in the past, reliving the best year of his life in an endless self-indulgent loop. But when he learns he’s going to be a father, everything changes. He’s no longer trying to save the world. He’s fighting to save his daughter’s future.

Unbreakable X-Men #1X years later and the Uncanny X-Men have been shattered by loss and tragedy and scattered to different locations around the world. At Haven House, only three remain — wounded, grieving and guarding the portal to the terrifying PENUMBRA. Can they stop the thundering darkness that has lurked below the surface for centuries, screaming to break free? Or will they fail and watch a vengeful god bring an army of tormented souls to the surface, crying for mutant blood?

v10.0: Lots of new fields and features!

Oct 01, 2025

Most of the dev team (Pim, Bernard, Michiel and AJ) have been working on upcoming updates for CLZ Movies, both mobile and web.

And we can finally release both today.
Here’s what’s new for your CLZ Movies mobile app.

It started out as a relatively small update in which we would add some new fields (just like we did for the books and music apps recently). However, the update has grown into a huge major upgrade, with several big new features that have been on our “to do” list for many years.

  • Editable episode lists for TV Series
  • Watch history: track multiple watch dates for your movies
  • Add your own YouTube trailer links
  • Extra fields for Box Sets: Purchase Price/Date/Store and Notes
  • A new “Features” fields, to track available features for DVD/BR/4K
  • The HDR field now allows multiple values, e.g. HDR10 *and* Dolby Vision

Check out some screenshots below!
