This product is by far one of the best coin scanner apps out there. It accurately located and confirmed errors on 15 coins I have. It's qr code feature is a game changer as well - you send the PDF that is auto generated for each coin in your collection to potential buyers, grading houses or friends etc. And they can read about it, scan the code and it takes them right to the listing to view it themselves. If your into coins or bills this is a MUST HAVE APP.
What needs improvement
Honestly, I can't think of a single improvement other than granting more scans per account level.
vs Alternatives
I have tried several others and they do not even come close to the grading and error identification accuracy. Amount the other apps I have tried were Coinin, Coin Snap, Coin Identifier, AI Coin Identifier and more.
