Latest update · v10.8.4

Fixed: * Further tweaks to the down-syncing from CLZ Cloud * Add, Edit and Action buttons could sometimes not be used if images were still downloading in the background

Recurring themes

Subscription & Pricing negative
Many recent reviews express frustration over the app's pricing model, including being charged despite having a subscription, unexpected charges, and the perception that the app is not truly 'free' due to paywalls for core features like unlimited cataloging and syncing. Some also find the separate subscription for CovrPrice and its limitations for export to be a 'money grab'. This contradicts the developer's minor bug fixes, as the core issue is the subscription system itself.R6R25R41R51
Cataloging & Database positive
Users consistently praise the app's ability to easily catalog comics using barcode and cover scanning, its comprehensive database, and its utility for organizing large collections. However, some note limitations with indie or older Golden Age comics requiring manual entry.R1R2R15R23
Performance & Stability negative
A significant number of recent reviews report issues with the app crashing frequently, being slow to add comics, and experiencing problems with the barcode scanner. This directly contradicts the developer's notes about 'further tweaks to down-syncing' and fixing issues with buttons not being usable if images were downloading, as users still report instability and slowness.R325R424R452R530
Customer Support positive
Many users highlight the excellent and responsive customer support team, praising their quick solutions and helpfulness. However, one review mentions a negative interaction where support was dismissive.R2R14R34R40
Value Tracking mixed
The integration with CovrPrice for tracking comic values is seen as a valuable feature by many. However, the necessity of a separate subscription for CovrPrice, the difficulty in linking it, and limitations on exporting data are significant drawbacks for others.R9R10R14R23

Who it's for

This app is for serious comic collectors with large collections who need a robust tool for cataloging, organizing, and tracking their comics, especially those who appreciate detailed databases and responsive customer support R2R26R27R34. It is particularly useful for preventing duplicate purchases and identifying missing issues R11R24. It is not for casual users looking for a free solution or those unwilling to pay for multiple subscriptions for full functionality R51R176R313. It may also be challenging for users with low vision due to small font sizes R8.

Evidence note: The recent review sample skews negative, with a significant portion of 1-star ratings focusing on subscription issues and app performance. This contrasts with the very high lifetime rating, suggesting a recent decline in user satisfaction related to these specific themes. The positive points are well-supported by numerous 5-star reviews, indicating that when the app works as intended, it is highly valued.

  1. [R1] 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. [R2] 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.
  3. [R26] 5/5 · US Amazing App!: I love this application! I have nearly 7,000 books catalogued. The days of notebooks and word documents are gone forever.
  4. [R27] 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] 5/5 · US Used for years: Highly recommended for comic collectors. Upgrades and added features improve it regularly.
  6. [R15] 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
  7. [R33] 5/5 · US Full Collection: I’ve used this app for my collection for years now. Customized folders, scanning ability and now the ability to connect with current eBay sales is great!
  8. [R34] 5/5 · US Great App-A Must Have: A great app for the serious collector. The lists that they maintain are usually complete and up to date. But by far one of the bests parts of this app are the developers and support team. If you find something missing, incomplete, or even just have a question, emailing the support team results in an almost immediate response and update to the database. No waiting until t
  9. [R14] 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.
  10. [R40] 5/5 · US Great to catalogue: Have my entire comic collection on the database, able to track value and changes over time. Support is wonderful!
  11. [R9] 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
  12. [R10] 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
  13. [R23] 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!
  14. [R11] 5/5 · US Couldn’t go without it: If you are collecting - you need this. While it is helpful on many levels, one particularly useful benefit is to be able to check the app on my phone and make sure I haven’t already purchased a comic before. Before I had the app I would end up with multiple duplicates. This solves that and much more.
  15. [R24] 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!
  16. [R44] 5/5 · US Great for managing collection: I’ve been using CLZ for several year and I’ve found it’s an easy app to scan and log what books I have (so I don’t keep buying dupes on accident). This was especially helpful when I was trying to complete my full run of X-Men to know which books I was missing. On top of that, I had an issue with my account recently and got locked out and support responded back quic
  17. [R6] 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.
  18. [R41] 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
  19. [R151] 1/5 · US Subscription Services INOP: I’ll change review once fixed. Have used app in the past and it’s great. Went to subscribe and was charged twice. And I can’t use any services. It says I need to subscribe to use services but if I click it it then says I’m already subscribed. Yearly is 20$, paid 40$, obtained 0 services. Sent in about 3 emails waiting on response but I’ve lost my only free time I’ll h
  20. [R5] 2/5 · US Love the app but: Love this app but they ask me to do a review every day. So I’m giving a bad feedback for that reason.
  21. [R7] 1/5 · US OMG: Stop asking me every 10 seconds to review your app🤨
  22. [R19] 5/5 · US Review: Tired of it asking for reviews. Otherwise I enjoy the app!
  23. [R51] 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.
  24. [R176] 1/5 · US Not free: Should not be listed as a free app. It should be listed as a $20 a month subscription service! Developers are missing you before you even download the app. False advertising!
  25. [R193] 1/5 · US Cost: Before you download this you have to pay a 20 dollar bill just to us any part of the app
  26. [R313] 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
  27. [R325] 1/5 · GB Waste of time.: At more than £10 I expected an app that didn't crash every few minutes. I really, really want my money back.
  28. [R452] 2/5 · CA Was good: Was a great app until the last 'update'. Now I am not able to add to my collection because the app closes down as soon as I click on the search online option.
  29. [R567] 1/5 · CA Always problems: With every update there's always a problem. Either you can't sinc or now, the thing keeps on crashing. The PC program is a charm by this app is infuriating.
  30. [R576] 1/5 · AU Constantly crashes when uploading via barcode: Been like this for months now tbh. Get your act together
  31. [R25] 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.
  32. [R164] 1/5 · US App doesn't work with CovrPrice: It doesn't sync with CovrPrice beyond the very first use and customer service doesn't understand why this is a bad thing. Avoid at all costs.
  33. [R262] 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
  34. [R371] 3/5 · CA Nice but not upfront about what it takes to get pricing associated: I’ve heard this is the best app to inventory my comic book collection and I wanted to get to know the values of what I had. What I wasn’t aware of was that by subscribing to covr price I was only able to get to see the values but not export them unless I had a full year membership with CLZ I would’ve appreciated them being upfront
  35. [R8] 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
  36. [R106] 2/5 · US Horribly Complicated: In an age when your grandparents can vibe code an app, this product has failed to evolve. Every other vendor is so much easier to use. If only they just copied their competitors.
  37. [R330] 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
  38. [R84] 1/5 · US Sucks: Couldn’t unsubscribe before way before 7 day free trial is over . it charged my account and still won’t let me unsubscribe
  39. [R121] 1/5 · US I keep getting charged: I cannot seem to get these guys from charging me $1.99 every month. I have requested this twice.
  40. [R204] 1/5 · US Not in catalog: I have to manually enter about 80% of the golden age comics that I purchased.
  41. [R373] 3/5 · CA More comics: Great so far. Except the library for indie comics or specialty comics is really lacking. Hopefully this is something that is being worked on.
  42. [R586] 3/5 · AU Unsure...: This is a good app EXCEPT it seems to not have older comics that I have....please someone help me sort it out
  43. [R615] 1/5 · AU Disappointing: Was really looking forward to using this as all the features looked great, but the barcode scanning doesn't work with the iPad 2 and it didn't want to download details of the first series I tried entering ("The Secret Service" ) and i don't have time to type in every title and take photos of the covers. Too hard, glad I didn't pay for it or I'd be seriously annoyed.
  44. [R424] 1/5 · CA Ruin a Good Thing: The last update, which I’m sure was put together to make the app better, has basically ruined it. It’s annoying. It’s clunky. Things like renaming titles (because this app has ALWAYS been a disaster with proper titles and sorting) is impossible now and doesn’t actually do anything. Yeah. What a waste and a way to ruin a good thing. I wish someone would just develop an app that t
  45. [R530] 3/5 · CA Excellent, but pricey.: Really great app for organizing your personal collection. SINCE THE UPDATE to iOS7 scanning by barcode is kind of difficult. When the window listing scanned items is closed it can't be opened again without returning to the gallery menu. Currently when it displays the long list of your collection the issues are organized in alphabetical order and each issue is in descendi
