Reviews from CLZ users
I was honestly surprised — and deeply impressed — by your decision to assist me through a version upgrade, especially considering that my original purchase was made more than 12 years ago.
In today’s software industry, it is rare to see such thoughtful and customer-focused support for a legacy product. Your response truly reflects the values and integrity of CLZ as a company, and I am sincerely grateful for your understanding and flexibility.
Thanks to your help, I can continue managing my music collection with peace of mind, and I truly appreciate the care you have shown in handling my case.
I do really like your app as it makes cataloguing my collection so much easier.
Wishing you a merry Christmas and a happy new year.
THX again for your help and professionalism!
Have a wonderful Christmas and a happy New Year.
Latest CLZ news
v10.5.1: (Android only) Smoother navigation between folders, book list and book details
A small update for the CLZ Books app, with two changes requested by our users and one optimization that we came up with ourselves:
Smoother navigation between folders, book list and book details
This one is for the Android users!
Our Android developer Pim was working on the app’s main screen and he saw some opportunities for improvement. Mainly to reduce slowness and stuttery behaviour when navigating back and forth between the folder list, the book list and book details page.
So instead of starting on the next new feature, we gave him a few days to refactor the code and improve existing functionality.
The result of Pim’s work is live now, in version 10.5.1 of the CLZ Books app.
We have been testing the new update quite a bit and we think it feels a lot snappier and smoother, especially noticeable on larger collections.
We hope you will notice the improvements too and that it will make you enjoy the app even more!
New: Disable the downloading of book values
In April 2025, in version 10.2, we introduced one of the biggest new features ever: the automatic downloading of book values. The feature has been requested by many users for years, so the introduction of this feature was a huge success: MOST users loved the new values!
However, a small group of users absolutely HATED the new feature. They found the values annoying, not necessary, too “commercial”, etc…
We did not see that coming…. our fault. Maybe with our years of experience as software developers, we could have expected this. Guess we were too excited about the feature ourselves 🙂
Looking back, we should have made the entire feature OPTIONAL from the start.
Of course, making it optional is still possible and that is exactly what we did for this update today. If you don’t want automatic values for your books, you can now disable downloading them via the new “Download Values” toggle in the Settings screen.
When you disable this setting, no book values will be downloaded anymore for any future books you add. On top of that it will also remove all automatic values you already have (any “My Values” you have will remain).
New: Search your database by ISBN13 or ISBN10
For all books in your database, the app normally stores the ISBN in ISBN13 notation, even for older books that original had an ISBN in ISBN10 format. However, this caused problems when searching your database using the ISBN10 notation, it would not find the book.
In today’s update, we fixed that, by including both the ISBN13 AND the ISBN10 notation in the app’s internal search index.
Searching your app by ISBN13 or ISBN10 will now find the book, no matter if you have ISBN10 or ISBN13 filled in for it.
Fixed:
- A couple of navigation issues
How to update your app to the new version:
- On your device, open the Play Store app.
- Search for “CLZ” and select the CLZ Music app.
- Tap “Update” to update the app.
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!
