  1. [R2] CLZ Comics collection database 5/5 · US Fantastic!: Legit been looking for something for my collection for YEARS!! Hands down simplest, complete, and well built collection app ever!!!!
  2. [R17] CLZ Comics collection database 5/5 · US Great for Inventory: I started using the app about two years ago now in order to just inventory my books and it has been great for that purpose. However, I recently decided I might want to sell some of my collection and that is when I found out the app is also great for letting me know which books are going up or down in value as well as letting go to the cgc site so I can see how many copies of e
  3. [R36] CLZ Comics collection database 5/5 · US Great comics collectors app!: I have hundreds of comics and needed an easy way to organize them by set and log each issue for future reference. The photo scan option for logging is SUPER helpful! I also used the price integration with CoverPrice, which is even more helpful, since I can see the real-time market values, if I choose to sell any. Thank you for an amazing app!
  4. [R39] CLZ Comics collection database 5/5 · US The Ultimate Comic App: CLZ comics is a godsend! I’ve been collecting for almost 50 years and had tried all manner of databases since the mid 90s. CLZ is the most user friendly, convenient, and reliable way of cataloging your comics. The barcode scanner embedded in the app helps immensely. You can track multiple collections as well as non comic items. Well done!!!
  5. [R3] CLZ Comics collection database 3/5 · US Tough to use if you’re a low vision human.: I really wanted to like this app. I downloaded and signed up for the year and scanned my first comic book bin quickly and effortlessly. Then the problems started. The font is minute and very difficult see on my phone. I thought I could solve that by installing it on my iPad, but I couldn’t link my account. The app kept saying “Apple sign in failed”. And
  6. [R12] CLZ Comics collection database 3/5 · GB Very good, but still needs work: There's been an annoying problem with this app always using the core database's series group which if you use your own is a pain. Browsing through comics could be better. For example, you can list your titles by series group but that then just lists all of the issues. It would be nice if you could drill down properly from series group to series to issues. Adding
  7. [R23] CLZ Comics collection database 4/5 · US Awesome: Restarted collecting because of this app. Very easy to use.
  8. [R6] CLZ Comics collection database 3/5 · US Love the Cataloging / miss the values: LOVE the ease of cataloging & sorting! HATE that you have to subscribe through another service for values.
  9. [R9] CLZ Comics collection database 3/5 · GB Good for lists, not for price guide.: It is a good app. I just wish it was easier to price and value issues. Having to subscribe to a third party to get values is not good. It is cumbersome and difficult to link to cover price. Can we not just pay for a higher tier subscription that does it automatically? If you are particular about giving data away out of the apple eco system and want a price
  10. [R14] CLZ Comics collection database 5/5 · US Very surprised: It has a scan feature that does not miss. Very surprising and allows me to have my inventory on hand and how the market for each comic is. Loving it thus far
  11. [R4] CLZ Comics collection database 1/5 · US Payed for subscription. Says I need a subscription: I payed for a yr subscription and when I scan barcode it says I need to pay for a subscription. So I went to contact customer service and it wanted me sign up to another website. It says easy to use but it’s been nothing but a hassle.
  12. [R5] CLZ Comics collection database 5/5 · US Best Comic Collection App…PERIOD!: Have used this app for years. It has so many user-friendly features, is super responsive, and the CLZ support team is top notch. Any time I submit a question or suggestion for improving the app, the team has never failed to respond quickly with a solution or just to acknowledge having received it.
  13. [R8] CLZ Comics collection database 5/5 · US Used for years: Highly recommended for comic collectors. Upgrades and added features improve it regularly.
  14. [R10] CLZ Comics collection database 2/5 · US Can’t utilize search or scan.: I like the capabilities of the app and the long standing support of the hobby/business. I downloaded the app, subscribed to the monthly plan, and none of the features will work. It just states that I have to subscribe to do that. I have already subscribed. I don’t want a refund, I want to use the service. Let me pay you to use your application please. Update: I atte
  15. [R15] CLZ Comics collection database 3/5 · GB Limited for the price: For the price, the offering is extremely limited. The good points stem from the fact that there is an extremely large database of information to draw from, including all cover art etc. However, the ability to synch between iPad and iPhone/PC is chargeable. To me this seems like a money grab. So what you are left with, for the price you pay is a very basic catalogue and wish
  16. [R16] CLZ Comics collection database 1/5 · US Paywall: Was looking for something like TCG player. A place to scan my comics for free. No, stupid paywall. Greedy as all get out. Least be like TCG and take a percentage but at least let me scan. Enjoy the nothing you got from me.
  17. [R25] CLZ Comics collection database 5/5 · US Excellent all around collection management: I downloaded mobile for a free trial and had purchased mobile and web within hours after seeing what this app can do. I added on the covr price feature which is tremendously helpful in determining what to buy, sell, or grade. The customer service is unparalleled. Had a question that was resolved with a very informative back and forth.
  18. [R26] CLZ Comics collection database 1/5 · GB Don't download this!: Right, This app is a con, I assume that since you're wanting to catalogue your collection, you have over 100 comics?! Right? Well, If you have over 100 comics you will have to PAY £10.99 to add an unlimited amount to your "list". What a con, This app is pointless. No one downloading this is wanting to catalogue their "100 comics", I mean come on.... This app is just a bla
  19. [R49] CLZ Comics collection database 5/5 · US Simply Amazing: This is the only review I have ever wrote for an app. CLZ makes it extremely easy to catalog, sort, and view my collection. I really enjoy that my slabbed comics have a CGC border look in the app as well. I am more of a comic reader with a 10 percent collector vibe, and using “find missing comics” is such a great way to find issues and covers I don’t have. There is a charge of $1
  20. [R76] Key Collector Comics App 1/5 · US U have 2 pay real moneys: This app is so horrible it sucks u have 2 pay real moneys
  21. [R97] Key Collector Comics App 1/5 · US Reason: It makes you pay for features you should get with the app
  22. [R27] CLZ Comics collection database 5/5 · US My experience so far: The app has a really good cover scanner and as a collector, the app makes it really easy to find which comics you’re missing and a particular run
  23. [R37] CLZ Comics collection database 5/5 · US Super helpful: As a dollar bin diver, CLZ has saved me so much money! I just scan the cover right on my phone and know if I need that book or a different dollar gem!
