CLZ Is Awesome
I would like to personally thank Alwin Hoogerdijk for his support. I’m recently new to CLZ and Alwin has been in direct contact with me on an issue that’s being worked. He’s followed along with an app update and ensured the update and functionality of the app. This kind of customer service goes above and beyond my expectations.
Thank you Alwin for your personal commitment to CLZs success. — Jeremy (USA)

Great tool for managing my library and eliminating multiple buying of the same book
This system has been a very strong tool in eliminating my purchasing multiple copies of the same book while simultaneously providing me with a listing of books I have read. This provides a synopsis of the book to refresh my memory on the book and in some cases reminds me of the pleasure the book provided or why I rated it so poorly.
I enjoyed the application so much I have the application for movies and my son has the application for comic books. Very reasonable price and delivers everything it promises. — ColBob (USA)

Amazing set of apps!
I have been using the CLZ apps for years to catalog my music, my books and my movies. The apps are easy to use, both in adding new titles and in viewing my collections. It is great to have all this information at my fingertips when I’m out at a record store or looking for a new movie to buy to make sure I don’t already have what I’m looking at. Highly recommended! — Kenrus60 (USA)

Latest Collectorz.com news

CLZ Comics (Android)

v7.9 Filter your Series list by Completed status

July 1st, 2022

Another nice update for your CLZ Comics app, with 2 new features that were requested by you all:

  • Filter your Series list by “Completed” status
  • New Setting for Series Images: Earliest Issue or Latest Issue

Filter your Series list by “Completed” status

This has been a recurring request since we introduced the ability to mark series as “Completed”. So we made it happen.
Just tap the checklist icon at the top and choose “Show completed” to only show all series that have been marked as Completed.

Note that the Series Completed flag is a manual flag. You decide if a series is completed or not. You can either set that flag in the Edit Series screen (e.g. from Manage Pick Lists) or just select multiple series in the series list, then choose “Mark as Completed” from the Action button menu.

New Setting for Series Images: Earliest Issue or Latest Issue

In your series list, the app has always shown the cover image of the latest issue for that series that you own. But some users indicated that they would prefer it to use the first or earliest issue of the series, because in most cases that is a more recognizable issue.

So we made it into a setting!

Other changes:

Next to the features above, we also added 2 other things, 1 requested (or demanded) by Apple, and 1 requested by the CLZ support guys and gal 🙂

  • Edit Series screen: modify the CLZ Series ID:
    This is sometimes necessary when your series entry is linked to the wrong Core Series. In general: only do this when instructed by CLZ support staff.

  • New “Delete my CLZ Account” option under Settings (iOS only):
    A new requirement by Apple, a way to to delete your account from the app itself. If you value your app, subscription and your cloud data, do NOT press this button!!! 🙂

Fixed for iOS:

  • New in the Settings screen, as required by Apple: a “Delete my CLZ Account” button.
  • Pull List: My Series now only works on your currently selected collection, instead of all collections
  • Small fixes to the most valuable comics statistic

Fixed for Android:

  • After tapping on a quick search series result, the keyboard wouldn’t automatically hide
  • Small fixes to the most valuable comics statistic

However, after running the “Update IMDb Ratings/Votes” and getting the “254 movies updated” message, have you ever wondered

“WHICH movies have been updated and WHAT was the change?”.

Well, not anymore, because with today’s update we are answering that question!

This month, more updates for the mobile apps (as always) and 5 big maintenance builds for the Windows software. I know it has been a bit quiet on the Connect end, but that is caused by the big translation project we are doing there. We will be swinging back to big feature updates for Connect soon!

The releases for May 2022:
