### 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.

### 2/5 — Just use a browser instead

*2026-06-10, version 1.8.5*

The app requires you to login TWICE to see your submissions/grades. 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.

### 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.

### 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.

### 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.
