Reviews from customers

I have vinyl, cassettes, and DVD's. This app does very well in organizing these different audio formats witih easily searchable parameters. Over the years, the capability of this software has greatly improved, and expanded it's database sorting ability. Their "Core" database greatly eases the entry of information.

After many years of looking, I finally found a database tool that had all I was looking for and more! I have used Collectorz for more than 15 years. Their support has always been great, too. It’s a fantastic database tool for nerds like me. The app is a great complement so that I can keep track on the go.

Great technology and service. Truly for a vinyl collector.

Would be lost without it. A safety net to avoid duplication when browsing for LPs. Also useful record of cleaning vinyl. Responsive ‘help’ team too.

After many, many years I bought a turntable and am rebuilding my physical music collection (mostly the recent awesomely good remastered pressings on high quality vinyl). CLZ Music (like their Books app) is a high quality, full-featured app. But the most important thing is that it is actively maintained by a dedicated group of developers who really care about the products. Nothing is more important than frequent releases as a marker of the vitality of an app. Highly recommended. (I am a career software developer, so I can tell!)

Could I say that if rock saved my life, the CLZ Music App saved me from going crazy? I’d definitely say so! Because ever since I discovered it and downloaded it to try it out, I’ve avoided spending reckless amounts on duplicate, triple (and even more, considering the reissues and various re-releases, which are often unnecessary) vinyls and CDs. It’s true, it has a cost, but believe me, it’s more than justified by the constant and continuous improvements being made, making the CLZ Music App an indispensable tool for navigating my personal collection of over 15,000 records, with the ability to add any kind of note related to the album in question—from catalog number to condition, musicians, recording studios, and packaging. In short, it’s the ultimate solution for any enthusiast, whether a collector or not. There are also apps for books and videos. In short, an inexhaustible resource for anyone looking for an app that serves as a convenient reference and aid. Highly recommended for everyone.

I needed to start a proper but straightforward Vinyl LP listing. CLZ is intuitive and logical, pleasant to the eye and it’s simple to learn as you go without any instructions. I like how it saves to cloud and can sync between ipad and iphone in the one app. I am keen to slowly put all my collection on!

Great tool for not buying dups in the great hunt for classic vinyl or cassette tapes. Been using this software for several years, just a great product.

After many years of neglect I decided to gather up and catalog my CD and vinyl collection. I thought it would take me a couple of months to do it so I researched it and settled on the CLZ app and I installed and paid the $19.99 yearly subscription. Well, what I thought would take me months actually took a couple of days, for 366 vinyl lps and 275 cds. I am totally satisfied and the app and service have far exceeded my expectations.

Have used for many years. Serious people behind.

In a world of streaming it's very helpful to have a catalogue of both owned music and one's favourite albums.

I love my CD’s & this app is the quickest, easiest app to catalogue them all. Awesome idea for insurance cataloguing for collectors.

So pleased I downloaded the CLZ app as it was just what I needed to catalog my vinyl collection. So easy to use!

Per la mia collezione di cd dopo diversi anni di utilizzo è diventata ormai indispensabile.

Really useful app, works well. Good database to search from, and any way you can think of to sort or filter your collection.

I have used this app for years. I have over 2000 albums and close to 800 45's. I have them listed in alphabetical order plus location.

Easy to handle perfect for a bigger collection.

CLZ Music is erg volledig en snel naar je hand te zetten. Ook snelle response bij vragen. Top!

I’ve been using the app for a number of years. When I first started using it, I found it met all my needs, and as time goes by and more updates are released, it gets even better. The best thing is that the developers really listen to customers and genuinely respond to suggestions. The platform is stable and secure, and the mobile version has prevented me from doubling up on purchases on many occasions. I have no hesitation in recommending this product.

I began using the CLZ music catalog App/web years ago to track my Vinyl/CD collection. It would have been amazing to have this app back when I started collecting. (Really amazing since I started my collection in 1968!) Kudos to the Team at CLZ for their always fantastic product!

Absolutely worth the annual fee.

The app makes "vinyl nights" great. I pass my phone to my guests & let them choose the next record to spin. A LOT easier than going through the bins of albums I have :)
Thank you for your excellent customer service. It is rare, & I appreciate your attention.

For a long time, I was looking for a way to catalog my music collection. CLZ has put an end to my search. The software leaves nothing to be desired. It’s easy to use and has a clear structure. I highly recommend it. Thank you, CLZ team.

This is an amazing piece of software. You don’t often find this level of attention to detail in 2026. It is so much more than just a music database for your CDs/ Vinyl. They recently added custom fields which is a game changer to an already fine program.
Don’t hesitate. Get it now!

I searched far and wide to find something that would serve my needs and this is it. I may not have a large collection compared to some but, It was aggravating to try and find what I was looking for before this app. That is NO LONGER the case. Many customizable areas too. Thank you Alwin Hoogerdijk!

As a collector of hundreds of music recordings in various forms, CLZ helps me quickly identify gaps in my library. As a result, it saves me money from buying duplicates, and also gives me an insight on the collection's overall value. The CLZ Team is doing great work.

Like other CLZ apps, the Music CD / Vinyl app is a great tool for any collector. Lots of fields to short and manage your collection by. My family uses it for vinyl and we can see everyone’s collection in one place. Makes shopping easier and avoids any accidental duplications.

Man findet fast alles (99%), auch gleich nach Veröffentlichung. Prima Sache für die Hosentasche, hat mir schon sehr oft unterwegs geholfen. Würde ich mir immer wieder holen, gerade für große Sammlungen ideal, volle Sterne !!!!

I’ve been using this app to track my CD collection for several years, and it’s not only brilliant but continues to evolve and improve with regular updates and enhancements. The creators have demonstrated that they really care about their product. Highest recommendation.

Si tienes música en distintos formatos, esta aplicación es ideal para tener a mano todos los detalles de los discos, artistas, pistas , etc. Si eres coleccionista te va encantar su diseño, facilidad de uso y la sincronización con la nube. Una joya para los frikis de la música.

This is a magnificent software suite which I have huge faith in, to allow me to keep tabs on my various music collection (classical, pop, humour). It is so slick and versatile and widely adaptable. The Team are so on the ball and forever refining the software. I am most appreciative of their skills.

With approximately 1500 cd’s I’ve tried several cataloging programs. This one is the easiest for both entering information and searching.

I use this app strictly for my personal vinyl inventory. I don't use it for valuations. It's so easy to use, has great custimation options and the dev team is always trying to improve and expand capabilities. I've been a user for four years, and I've tried other apps. I think I'll stay here.

This is the premier software for CD collectors, at least that I've come across in many years. Backed up by a very active and responsive support/development team.

Have been using Clz Music for years and have been extremely pleased throughout. Have enjoyed lots of upgrades over the years and it just becomes better and better. Very easy to use, even for beginners. I can heartily recommend Clz Music.

Excelente aplicación para catalogar tu colección de música.

This app alows me to be much more organized with record collection, which already includes a considerable number of itens. Without it, it would be completely impossible to do that.

I hesitated for a long time before trying this, or any app, to log all of my music, as I have close to 6,000 CDs and around 1,000 vinyl albums, mostly classical, jazz and “world”music.
And it’s classical music that produces a particular issue, which is how do you want to file/look up a CD with multiple artists, playing multiple composers? The CLZ app makes this all entirely possible by the use of tags and editable look up labels for artist, composer, label, amd many many more.
So I can now look up Jean Efflam Bavouzet and Manchester Camerata playing Mozart’s Piano Concertos at Stoller Hall, on the Chandos label, which is a recommended recording by Gramophone Magazine in any way I choose, and know it’s filed under Mozart Piano Concertos.
I invested a while uploading all of my collection, but it has now come to bear fruit in searching and cross referencing.
I’m also happy with the cloud back ups, which for me real confidence. They are also very very responsive to questions and feedback, and development ideas.
I was initially hesitant, but it’s truly exceeded all of my expectations.
Highly recommended!

I needed something to stop me repeatedly buying the same CD when browsing in charity shops, downloaded this and within 40 minutes I had a collection all safely registered. Now to tackle the remaining collections.

I’ve owned clz app in its evolution from music collector to clz for many many years and I’ve found nothing better. It is well laid out, easy to add or edit and continues to evolve. I normally never buy an app that is subscription based but the mobile version of clz is acceptably priced so have been happy to continue with my subscription. For context, I own about 800 vinyl and a 1000 cds and occasionally I’ll add to this. I like the recently added connect to eBay which gives me an idea of vinyl value.

I have been using CLZ since its early days, it’s easy to use and makes life a lot easier. My favourite element is being able to check your collection, when considering a new purchase.

Easy to use / really helpful / love it.

Great app, easy to use and, especially, it helps me avoid buying double stuff since I have my record collection List in my hand. Thank you!!!

La migliore app per la catalogazione degli album musicali in ogni formato, cd, vinile, Dvd ecc. con un database completo di titoli pubblicati a livello mondiale. La preferisco a Discogs anche per la possibilità di personalizzare i campi a proprio piacimento.

Fantastic, could not live without this app!

Your database can be slplit into various collections so that you can store vinyl, cds etc in their own collection. Entries are added either manually, from the CLZ core or by scanning in the product bar code. The app is multi platform so if you have the web/PC/android versions they are always in synch

Delivers exactly what it says. Great for managing music collections (cds, vinyls). It has what’s needed without hassle. Stable, intuitive, easy to use.

I have been using this excellent music database since 2017 and can highly recommend it. There has been many updates since then and everyone has enhanced the users use of this great system.

I have used the app for years and been very happy with it. I also use Comic & Movie app from same provider. Support and functionality is very good!

I have been using this database for years and am completely satisfied. I have tried many different databases, but always come back to this one. The database is virtually complete. It offers the possibility to store a lot of information and is easy to search. The team behind the programme is constantly working to improve the application. If you have a question, they respond quickly and make every effort to resolve your query or problem. In short... for me, it is the best music database to date.

Durante muito tempo procurei por um catalogador que fosse prático e fácil. Já estou a muitos anos usando esse aplicativo. o suporte técnico é maravilhoso e eles estão sempre atualizando. Tenho também o CLZ Movie que gosto muito. O aplicativo é prático, fácil, um designer bonito e tem uma base de dados gigante.

Being old fashioned I like physical discs either vinyl or cd. I have a habit of wandering through charity shop music shelves. Having my collection on my phone is just perfect - no more duplicated discs.

This application is excellent with a dedicated team and frequent updates with additional functionalities. They also do a great job of communicating their changes.

I have collected vinyl for more than 55 years and built my own database to record and search my collection but everytime technology overtook my efforts until i found CLZ a few years ago. It does everythingi had ever dreamt of. Smoothly, efficiently and with gorgeous presentation and simple use.
I can not recommend this product highly enough. CLZ care and understand what collectors want!

I’m loving this app. Collecting music for over 40 years, my collection is extensive and I have trouble remembering everything I own. The depth of the database is impressive and the developers are very helpful.

Using the apps for a long time it answers perfectly my needs in term of listing, classifying and categorising my vinyls and CD (about one thousand).

Just eveything you need to take care of your collection.

The app is backed by a robust database making it easier to enter discs. Using my iPhone, I added my 100+ disc collection of Christmas/Holiday music in about 1 hour. The vast majority by barcode, some by title/artist, 12 by manual entry. Highly recommended.

2021 Super Kombi zum Desktop PC, damit sind alle CDs immer dabei im Handy. Kein Doppelkaufen mehr ?. Und ein super Support!
2026: noch immer Kunde und Nutzer der App. Die Kombination macht es perfekt aus Desktop und App. Weiter so.

The best CD and media Android cataloguer I know!
