  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. [R8] Key Collector Comics App 5/5 · US Great app: Easy to use and a huge help in knowing what’s hot in comics
  4. [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
  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. [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.
  8. [R4] Key Collector Comics App 1/5 · US Be better: Work on your price updates
  9. [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.
  10. [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
  11. [R31] Key Collector Comics App 1/5 · US Double the price now?: You’re only gonna lose customers, especially when the app freezes on the scanning screen.
  12. [R40] Key Collector Comics App 1/5 · US Needs work: Trying to use the sold option to make sure I know what comic issue I sold. I can’t event get anything at all. Seriously you guys charge a monthly subscription for this??? Slow and glitchy too don’t even bother
  13. [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
  14. [R37] Key Collector Comics App 1/5 · US Reason: It makes you pay for features you should get with the app
  15. [R57] Key Collector Comics App 3/5 · GB Pay walls!: Below is my review from 2018. Since then most of the stuff I used in the app has disappeared behind pay walls, so I very rarely even use the app now. 2018 Review: 5/5 Excellent App! I use this on a regular…well worth a download.
  16. [R76] 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. [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.
  18. [R43] Key Collector Comics App 2/5 · US Nice app but very inaccurate pricing!: Pricing is very inaccurate for variants and independent comics. I don’t recommend using this app as a price guide.
  19. [R36] Key Collector Comics App 3/5 · US Initial review: I haven’t found a way to export my collection and do a CSV file or someway to get into a spreadsheet would be nice.
  20. [R46] Key Collector Comics App 1/5 · US No Export: I would advise looking for an app that would allow you to export your collection and data. I would’ve given this app five stars, but there’s no way to export your own issues or wishlist to a CSV file. When going to cons or sending a list of what you want to buy or sell this app is of no use. Especially since I’m paying month you would think I would be able to at least get a list of all
  21. [R75] 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
