All I can say is WOW.
A friend of mine has two or three of your apps. I saw him updating his movie collection and first learned about them. I can't believe the scale and scope of the kind of data that can be customized and stored. I signed up for the trial but I'll keep subscribing for sure.
Really amazing and clean apps. Reminds me of the old days. Keep up the great work.
Latest CLZ news

It’s another exciting week for new comic releases, with a few standout issues that are definitely worth adding to your pull list! Let’s take a closer look at what’s hitting the shelves this week:
First up is The Amazing Spider-Man, Vol. 7 #35, a particularly notable issue as it marks the final issue before the series reaches the massive milestone of issue #1000! With such a major landmark on the horizon, this is a great time to catch up with Spidey before the next chapter begins.
Our second highlight is X-Men, Vol. 6 #36. This issue looks set to kick off a new chapter for Marvel’s mutant heroes, with DNX beginning here. If you’re following the latest developments in the X-Men line, this is one issue you’ll want to keep an eye on.
Last, we take a look at Hammerfist #1 (Image). A brand-new series from Image Comics, written by Rick Remender and illustrated by Steve Epting. The series follows a washed-up hitman who is forced to become an unlikely hero.
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!
Today, a nice server-side update that will improve the “sorting by title” for your books.
A bit of background:
Our CLZ Books mobile app and the CLZ Books Web software have always include a Sort Title field, right under the Title field in the Edit Book screen. You can use it to control the sorting of your books when the app is set to sort by Author/Title.
For example, a book titled “The Client” will sort under the “T’s” by default. But if you change the Sort Title to just “Client” (removing “The”), it will sort nicely in the C section where it belongs.
However, you needed to do that manually for all books where is was applicable.
But not anymore!
