Precious Coin Tester

It catches even 0.5 mm difference. I thought it is poor app when I got one star. Actually, I mistook actual diameter.

I bought to test U.S. 90% gold and silver coins. There are only 2 coins that be tested for free. A one silver dollar and a one ounce twenty dollar. No other denominations available without a subscription. Also, you can’t use the special parameters section without a description. After paying $30 for the device, I expected more options.

Econ 101: Price up = demand down Subscriptions are generally reviled, so, perhaps you could increase your revenue by figuring a way to segment your prospective customer base. Maybe a one-time fee for just the *custom* tester (i.e., no access to the coin library). Or maybe: One-time fee—say, $9.99—for access to the current database but some additional fee for the annual update (heck, and even a $1.99 annual “maintenance fee” for a “Basic” plan). For example, I don’t buy rounds; I buy old silver. I’d pay 10 bucks for the current library, but I have no need for annual updates. Let those who need them have the option to buy them. More money is made via a “Volume, volume, volume!” strategy than by exclusionary pricing. How many new “casual users” could you entice with a lower-priced “Basic” plan?

The app used to be great, everything was free to test. Now you need to pay 3$ a month. Ridiculous

Paid for a subscription and server always down. A refund would be nice!

Gave me a 3/3 rating for a glass jar while testing for ASEs. Just another data point, don’t bet the house on just this app.

Very helpfull if you have hearing loss or tone loss

Didn't fail any of my coins even when I pinged the wrong ones on purpose. Passed an ASE as a gold double eagle a couple times in a row 3/3.

This subscription model is tired lame and needs to be put out of it’s misery. I’m not paying $36 a year for an app I might use 2 times a month. My dealer has a tester that I can use for free. If you want my money then either charge $.50 a month or 4.99 for a years worth of updates. Until the I’ll find another to check ALL of my coins for free.

This app is a joke for real. First of all, misleading to have access the manual feature so you are force to subscribe. After subscription, only then tells you that the manual is not 3/3 accurate. Also, the results are varies with the same coins. 2023 Britannia silver 1 oz is not even in the coin list. It so hard pick the region as it’s very sensitive when you’re rolling the region choices. Don’t waste your money to subscribe, its a useless tool.
