  1. [R2] Key Collector Comics App 5/5 · US Best comic collecting app and pricing database I've found so far!: I've recently been tasked with organizing and cataloguing a massive collection of gold & silver age comics, and had been looking for a solution for building a master list of all the books, and this one has been by far the clear frontrunner for apps like this. I've tried several others, and Key Collector has the most thorough data o
  2. [R5] Key Collector Comics App 5/5 · US Love the My Collection Features!: I’ve been using this app since day one, it’s always been great to find the information on key comics, best out there. I took a hiatus from collecting for a few years and am slowly getting back in it and when I started using the app again I found the my collection feature. You can now store you collection on the app and track its value! Even better, the scanning
  3. [R10] Key Collector Comics App 1/5 · US Doesn't Have A Ton of Titles: I really like the interface, but it basically doesn't have any of the 300 comics I own. I'm not interested in earning points to do their job of cataloging and uploading them either. What's the incentive? Sorry, but I really need something that's convenient and not making me do extra work during my free time. :c
  4. [R12] Key Collector Comics App 3/5 · US Kinda confused but I like it: Good app just wish it wasn’t so confusing and behind a pay wall for stuff also can’t find a lot of comics I have
  5. [R6] Key Collector Comics App 3/5 · US Frozen: Nice app when it works but my iPhone freezes up randomly when using the scan function
  6. [R7] Key Collector Comics App 1/5 · US Seldom Work as Designed: The older basic version was better. Now with the scan to search feature the app freezes after 3 scans. You have to close the app to scan more. When the scan works and shows the details for the scanned book, let's say I want to click on the series and see more issues. You can't because this feature seldomly works when arrived from the scan feature. You have back out to the
  7. [R8] Key Collector Comics App 5/5 · US Great app: Easy to use and a huge help in knowing what’s hot in comics
  8. [R1] Key Collector Comics App 1/5 · US Price Gouging: With no reason of any kind since the app is pretty archaic, they DOUBLED the cost to “certain” individuals while leaving it cheap for others. Scam and a ripoff. No one from the app responds. Cash grab.
  9. [R16] 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
  10. [R23] Key Collector Comics App 5/5 · US The best comic app out there: The best comic app out there hands down have tried at least five different ones and this one is the best I’ve come across and for the price for a year is unbeatable
  11. [R4] Key Collector Comics App 1/5 · US Be better: Work on your price updates
  12. [R13] Key Collector Comics App 1/5 · US Artificial hype and market manipulation: With the recent popularity super obscure and independent comic books, a lot of the titles have been featured on this app on their “keys of the week” “hot 10” and “trending 20” tabs causing the over hype of under ordered books and independent titles also causing market manipulation in some areas.
  13. [R79] Marvel Unlimited 1/5 · US Doesn’t work offline: Kind of defeats the purpose if I can’t read the comics on the subway or a plane or when I otherwise don’t have internet even if I DOWNLOAD THE CONTENT ON MY DEVICE!!! Why is there a download option if I can’t access the file without internet? You’re competing with video games Tik tok you need to REMOVE friction!
  14. [R91] Marvel Unlimited 1/5 · US Great unless you want to read comics offline: No matter what I do now this once great app will only let you read comics while on Wi-Fi which is great unless you download a bunch of comics for say, a flight and none of them are available. And if you contact support they say there is nothing hey can do. How about give me my money back?
  15. [R99] Marvel Unlimited 3/5 · GB Marvel unlimited app: Good app, lots of comics. Unfortunately you cannot access your downloaded comics without an Internet connection (which kinda defeats the point) !!!!
  16. [R108] Marvel Unlimited 3/5 · GB Great but downloads are broken: Been an unlimited subscriber for years and I freaking love it. Enjoying the app redesign, despite the occasional bugs. I’m only putting 3 stars because currently Downloads are broken: every time I try to open my downloads tab, the app crashes. Very inconvenient to read comics while travelling.. will gladly change this to 5 stars once that’s fixed!
  17. [R15] Key Collector Comics App 3/5 · US Good but could be better.: Prices sometimes are not current to sold listings. It’s great to have the information about what issues are of note, but when seeing the prices on the app and going to eBay to see sold listings…it’s different.
  18. [R21] Key Collector Comics App 3/5 · US Jwtone: Great app for cataloging. The pricing is so far off very disappointing. But other than that I really enjoy keeping track of what I have. The 3 star review is based on pricing and it can’t find a lot of comics.
  19. [R28] Key Collector Comics App 1/5 · US Great app, too expensive: Was my go-to app for ease of adding books. Then they decided to double their rates. No reason given, seems wholly unnecessary. Not worth the increase when I have to search eBay sold for a more reflective view of actual prices anyway.
  20. [R9] Key Collector Comics App 3/5 · US Sources? Market values? What happened?: I’ve been using this app since its inception and I have seen it grow into what it is today. The best feature it has is the camera scanning ability. That has to be my most favorite feature to use! It can be improved, though. There are a few bugs. It crashes now and then and you need to close and reopen. After you’ve scanned a book and its details come up, i
  21. [R19] Key Collector Comics App 2/5 · US Scanner no longer works: I paid for a 1 year subscription. Scanned maybe a dozen comics and the scanner stopped working. That was the main reason for me paying for this app. It is also very difficult to look up comic prices. Not happy. Would like a refund as I’ve only had it an hour or two.
  22. [R64] Marvel Unlimited 2/5 · US Honestly it’s frustrating: I used the free trial and it keeps telling me I still could use it even but when I click it i have to pay its misleading fees
  23. [R81] Marvel Unlimited 3/5 · US Made me pay for a trial?: The app is fine, i love comics as much as the next person and this app is good for reading them. But I decided I don’t like this app during the FREE trial, then a week or two later I open my app store and I can’t download anything because of a pending fee for something I shouldn’t have to pay. Good app, money hungry devs.
  24. [R94] Marvel Unlimited 1/5 · US BEWARE it’s Scam: If you’re reading this don’t buy this scammy app, 2 times has this app has scammed me, which I’m reluctant to admit. They advertise for a free trial, then they take your money bc there’s no free trial, then when you complain nothing happens. Now this happened about 4 or 5 years and I forgot(UNFORTUNATELY)then the other day I came across the app again, I thought it’s free, I’ll tr
  25. [R115] Marvel Unlimited 1/5 · GB Steals money: I canceled my subscription around 3 months ago and they have still charged me every time when you try to click customer support or manage subscription nothing happens and sometimes it takes you to a site that’s untrusted by apple because it’s a financial risk
