Excellent App
I have been using CLZ since I got it on disc ages ago. The transition to an app and all the continuous improvements they do make this best app for tracking your collection.

Expedient support
Many thanks for the expedient support and it's worked a treat as I've used the forgot password feature to update and successfully log in to the mobile app with the new details.
You provide an awesome suite of tools and services so I think it's nice to highlight and celebrate the global impact of what comes from hard work and passion from people like yourself and to reflect back an echo of how these products become part of our routine and how they feed into the storytelling we have with others as that's the real joy of a lived collection.
Your help has been very much appreciated and hopefully there's a lovely weekend ahead!

Excellent apps
I have just started with the books app but been using your Music and Movies apps for years now and both are quite excellent as I have thousands of each of those.
Now on to books, LOL.

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.

Adding albums by scanning barcodes is one of the most popular features of the CLZ Music app. Just scan barcodes, bleep, bleep, bleep, and the scanned albums are added to a “queue”. Then use the Add button at the bottom to add all queued albums to your database in one go. Quick and efficient.

However, we always like to keep improving the app, or at least give users multiple options. So today we have added a new “One-by-One” mode to the Add by Barcode screen, that is, without a queue.
