📝 About this app
This app offers a cheap and easy to use method to help detect fake bullion coins, by examining their resonance frequencies.
The resonance frequencies of an object are determined by the objects shape and material. If the shape and weight of a silver coin is correct, but the material is not actually silver, then a resonance test could detect this.
This is also known as a "ring test" or "ping test".
Unlike the manual "ring test", this app does not require that the user knows exactly how each coin should sound. The app will also detect resonance frequencies above the range of human hearing.… View full description on the official store →
