Great app
Great app I had a few issues to start with but contacted the help line and explained the issue and they resolved the issue. When it comes to finding a movie to watch from my ever increasing unwatched collection I select unwatched movies and shake my phone and it gives me a random movie to watch , which can be an interesting title I haven’t seen yet.

Best comic app + brilliant customer service!
I love this app, it completely changed how I manage my collection. I especially want to highlight the support team: it’s amazing how fast and helpful they are with every request. Dedicated customer service like this is rare nowadays. Hats off to the developers!

Incredibly helpful
I have found all of these apps to be incredibly helpful, user friendly and just what I need really. I use 4 of your apps now and check them regularly.
My film and tv library is close to 1000 and my books nearly 300. I visit charity shops regularly and without the help of these 4 apps I would be buying multiples all the time.

Your customer service is right on point
As always, your customer service is right on point and I thank you for that. Good customer service is getting to be somewhat of a rarity these days, so when I find it I'd like to spread it far and wide!

v11.0: Create your own Custom Fields!

Jul 21, 2026

This is it, the big v11.0 update for your CLZ Movies app. Version 11 is a huge step forward in the customizability of the app. And I am not talking about tweaking the look and feel here, like layout, colors, fonts, etc… No… this time we are giving you the ability to actually customize the database itself, with your own “Custom Fields“!

The Custom Fields feature will let you create your own data fields, to catalog any information for which the app does not have a built-in field. You can create text fields, number fields, date fields, Yes/No toggles, pick list fields and much more.

All fields you create can be edited on a special Custom Fields tab of the Edit Movie screen. The entered data will nicely appear in a special section on the movie details page. And of course, you will be able to use the fields like any built-in fields, that is, sort on them, use pick list, date and toggle fields as folders, search your text fields, etc..
