And manual username/password entry, not thumbprint or FaceID. So, very tedious and slower than a browser. It’s not a native app either but a web app. All around clunky. I want to like it as I check for grades and submission status often. ### 2/5 — Keeps Closing, glitches need fixed *2026-03-07, version 1.8.4* Every time I try to verify a coin or up something app closes ### 2/5 — Keeps Crashing *2026-02-27, version 1.8.4* Trying to scan bar code, app keeps crashing. Need to improve. ### 2/5 — Not Great *2026-01-05, version 1.8.4* The app crashes every time I try to look up a coin by its certification number. For such a prestigious company, their app is woefully inadequate. ### 1/5 — Garbage App *2025-10-11, version 1.8.4* This app is a disaster. Someone at NGC should see what PCGS is doing and copy it. Hard to believe that a company like NGC can have an app this bad. ### 1/5 — useless *2025-10-07, version 1.8.4* unsure what app is used for; still ISO of coin app to catalog my collection & learn more about my coins ### 2/5 — Will not open *2025-09-16, version 1.8.4* Looking for information about a coin. The one offered for sale when I used the numbers came up as good when I looked for pop data it listed one as details and did not show the one I was interested in. A seller is most likely going to lose the sale . I updated the app and it does not seem to want to open correctly ### 2/5 — Hard to navigate *2025-09-11, version 1.8.4* NGC needs to update this app. Remember guys people are trusting you to grade their coins and if they can’t even navigate your site, it doesn’t look good. ### 1/5 — Genuinely the Worst I’ve Seen *2025-08-31, version 1.8.4* Had some NGC coins added to the collection recently and wanted to add them to my digital collection like I do with my PCGS coins. THE APP IS TERRIBLE. None of it actually does anything, it just sends you to the website to do things. Along with this, the app signs you out once you close it making you log back in. This feels like a high schooler built an app for a class project and submitted it for like a letter grade of C-. Genuinely so terrible and the reason I’m going to be sticking with PCGS. ### 1/5 — 鑑定写真 *2025-08-26, version 1.8.4* 検索しても写真が掲載されてない ### 1/5 — Lost the 2 best functions *2025-07-31, version 1.8.3* You can no longer scan a coin and see if its a Toppop or how many coins graded higher also you can no longer view Total Graded by NGC Census Not Available?? I hate useing the website for Census its just a link really we are in 2025 ‼️‼️ ### 1/5 — horrible app *2025-07-30, version 1.8.3* It’s a shame that every time I try to scan an NGC barcode the app crashes. I wanted it to operate more like the PCGS app does, but I wasn’t impressed. NGC, you’ve got high standards for your grading criteria, apply that to your app development. ### 1/5 — Scan does not work *2025-07-25, version 1.8.3* When you put the number in or scan it just kicks you out ### 1/5 — App Crashing *2025-07-19, version 1.8.3* Keeps crashing every time I try to scan or look up coins ### 1/5 — Poor *2025-07-16, version 1.8.3* Not user friendly! ### 1/5 — Most illogical app ever *2025-07-05, version 1.8.3* Just trying to add a coin to my collection. Such an ordeal just to log on. Cant find coins entered. Just so illogical. Ho benchmark pcgs. Hire some cheap summer interns to update app. ### 1/5 — App is broken *2025-07-03, version 1.8.3* When you go to scan the coin it quits I use to use this app all the time why all the sudden does it not work? ### 1/5 — App constantly crashes *2025-06-07, version 1.8.3* The app worked fine in my iPhone 15 for a couple days. Then the app crashed and closed on its own when trying to scan barcodes on slabs to authenticate. Poor functionality performance from my experience. PCGS app works perfectly. Maybe it’s my phone but my phone is updated, PCGS app is updated, and no issues with my phone. If this is a reported issue please fix. Is this feature only available for paid fee? ### 1/5 — Worst app ever *2025-05-10, version 1.8.3* This is easily the worst app I’ve ever used from a company of this size. It’s not user friendly at all. ## Most critical reviews (10 lowest-rated) ### 1/5 — Undermines NGC’s credibility *2026-07-13, version 1.8.6* Constantly acts like it’s been hacked into. It continually asked for you to sign in… like right after you’ve signed in and also when going from one tab to another. For example, to check submission status, it takes three logins. And then, after you’ve successfully logged in during the same session multiple times, it tells you that you need to change your password. This is behavior that security experts say indicate a site has been compromised. Oh yea, just who I want to trust my valuables with. ### 1/5 — Free No More! *2026-07-03, version 1.8.6* I used this app regularly to verify NGC slabs by using the scanner feature. Not anymore! With the new update comes the mandatory membership. Not cool and certainly doesn't make me wanna run out and become a member. FYI. PCGS scanner app is still free.... guess they care more about keeping their fakes out of the field more than making a quick buck. ### 1/5 — Still sucks as of 17-June-26 *2026-06-17, version 1.8.5* I read all the negative reviews, then I saw the app was updated a month ago, so gave it the benefit of the doubt. That was dumb. Overall functionality is generally limited, the Ux is shaky and isn’t well mapped. What made me delete the app immediately, though, is the exact function I was looking for; some place “official” to track my coins (like the PSA app…). This app advertises that function, but to get to it, after you have logged into the app, you click the button, which opens a browser window, where you are prompted to… log into again…(?) Annnd when you do, you get an error. Just get a notebook and a pen. It’ll be less frustrating and save you time. ### 1/5 — What happened? *2026-05-09, version 1.8.4* I’m running iOS 26.4.2. Anytime I run a scan on a container, the app just crashes. Can you fix it, please? ### 1/5 — Garbage *2026-05-03, version 1.8.4* This app is complete garbage. It doesn’t work at all. It will not scan barcodes and when you enter a barcode, it just says. Valid barcode don’t waste your time! ### 1/5 — Cannot verify barcodes *2026-04-02, version 1.8.4* This app is bad to say the least. It crashes every time you scan or enter a cert number. Going to stick with PCGS because their cert lookup system is incredibly smooth and easy. ### 1/5 — Really not that great *2026-02-23, version 1.8.4* The most useful function of this app has been the ability to look up coins based on their serial numbers. Well a recent update has caused that function to crash the app, which then closes. Been waiting for several weeks for a fix and nothing. ### 1/5 — The. Price guide *2026-02-09, version 1.8.4* Doesn’t work ### 1/5 — Missing the Mark *2025-11-25, version 1.8.4* I am a huge fan of NGC in the coin grading and encapsulation space, but I have been routinely let down by its website and mobile app— I could list dozens upon dozens of examples. I would go so far as to say NGC’s IT department is incompetent and is doing the company a disservice, especially when compared to the likes of its number one competitor, PCGS. Something needs to change. Soon I hope. ### 1/5 — Useless *2025-10-15, version 1.8.4* Doesn’t give anymore information than the label on the coin. No mintage or value information. Before what they call an upgrade that information was on the app. This is by far the dumbest so called upgrade ever. ## Most praised reviews (10 highest-rated) ### 5/5 — Great *2026-02-08, version 1.8.4* Love it ### 5/5 — Russ *2025-01-12, version 1.8.0* I love the program BUT needs update !!! I’m sure your working on an update, can’t wait for the fix and changes. ### 5/5 — Not compatible with ISO11 *2018-03-02, version 1.0.3* This is a great app. But unfortunately it does not work in ISO11 ### 5/5 — Happy for this App *2017-03-03, version 1.0.2* While I am happy that you all finally have this as an official app instead of just the separate mobile site, can you please incorporate the price guides into it as well? That information will be much more helpful then just the census alone. Otherwise great app so far! ### 4/5 — Vous avez un numéro *2024-12-21, version 1.8.0* C’est moon is my dream andlmq’´´´est ### 4/5 — Recommend though I would like to be able to browse some coins and old coins although good app *2021-11-03, version 1.7.1* Good ### 4/5 — NGC APP. *2019-10-08, version 1.6.2* There had been a problem with the price guide not working within the app. but it now seems to be working correctly.The app. is a very handy and useful informational tool to both verify a coin’s authenticity as well as research information regarding mintage,the number of coins certified by NGC etc. ### 4/5 — Nice app but could have more *2017-04-19, version 1.0.3* Its a nice clean app to navigate the coin census especially. I would love access to my coin submissions though. ### 3/5 — Used To Be Much Better *2023-10-07, version 1.8.0* Not sure what happened, but the last few versions are much worse (i.e. barcode scanner does not always work, adding coins works sometimes, verifying multiple coins does not always work, etc.). I hope NGC raises the bar and at least creates a stable application for iOS. ### 3/5 — Total value *2023-01-13, version 1.7.1* Why can’t there be a simple total value of collection? We have to click on coins to add them up? Please add total value of collection. PCGS has it.
