About this app

When you get a silver or gold coin with correct weight and size, how can you know it is not a fake coin made of other cheap materials? Traditional ping tests can distinguish true gold or silver coins from counterfeit ones in cheap metal. But you need good ears!

Precious coin tester helps you listen to the sound generated by the ping test and will tell you whether the coin is a cheap metal fake*. So no more worry about the fake gold or silver coin!

You can choose your coin from a catalog including more than 30,000 coins**, where more than 100 of them are free. Nothing found in the catalog? Defining coin's parameters by your own is also another option**!

- How to ping the coin?
Hold the coin on the tip of one finger near the mic of your phone/tablet, and knock the coin briefly with another hard object. Hold still the coin while it rings. When the sound of coin has diminished, knock it again.

Searching for coins is not easy. By country look up would be easier. No "save" feature for desired coins. Subscription based, which is just a scam to keep money rolling in. Latest version "locked" most coins. Most use this app spontaneously so unless you want to ALWAYS pay "unlocked" coins are extremely limited, so rendering app almost pointless. Was about to recommend this app along with the pocket pinger, but this app is now just a curiosity, which will also make it a harder sell. Unfortunate.

Used it every once in a while with my coin ping tester, like maybe once every couple of months. Now they want us to pay a subscription fee for something I very rarely use. I would buy it if the app had a flat fee. Pretty ridiculous to charge monthly.

Hello, we are sorry for the impact. It is possible to subscribe for one month and unsubscribe immediately to stop the auto-renewing (whereas the subscription is still valid for the whole month). This operation is repeatable. We are also studying other methods for very occasional users. Please follow us and keep informed. Thanks for your supporting!

Most coins locked behind a subscription, not cool. App is touted as a main reason to buy the tester in the first place.

Hello, we are sorry for your unsatisfaction. If you mean "Pocket Pinger": we are completely two different entities. You can download and use our app (which provides 100+ coins free to test) despite you've bought a pocket pinger or not. Since we run on our own, we need to charge some fees to make the project sustainable. Hope you can understand.
