About the application:

This apk offers a cheap and simple to use way to assist 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 try should detect this. This is also known as a "ring try" or "ping test". Unlike the manual "ring try", this apk does not require that the player knows exactly how each coin could sound. The apk will also detect resonance frequencies above the range of human hearing. This youtube video shows how to use this app: http://www.youtube.com/watch?v=5pZnqp3bl3A This gratis ver supports three types of coins. Buy the full ver to receive help for a lot of more coins. How to use this app: 1. for best results you could perform this try in a reasonably silent room. Some electronic devices may produce high-pitch noises which should interfere with the test. 2. Choose the kind of bullion coin to try from the drop-down list. Currently only three types of coins are supported. 3. Press the microphone button to begin the test. 4. Blue lines indicate the expected resonance frequencies of the chosen coin. 5. Balance the coin on your finger, near the microphone of your phone. Tap the coin using your fingernail, or use some hard object. Do NOT use a second coin to tap the first one, since the sound from the second coin may affect the results. The sound level needed depends on the sensitivity of the microphone in your Android device device. For most devices is it sufficient to gently tap the coin with your fingernail. 6a. If the sound matches the expected resonance frequencies of the chosen coin, you will see a green check-mark. 6b. If there is too much noise, or if the sound does not match the expected frequencies, then you will se a red cross. 6c. Some Android device devices have microphones which are unable to record high frequencies above ~10kHz. If the apk detects two out of three expected frequencies, it will indicate this with the fraction "2/3", and report that device limitations might be the reason why the latest frequency was not detected. 7. Some practice may be required to produce a clean enough sound from the coin. The apk is sound-activated, you can tap the coin once more to do other test. Needed permissions: Record audio - To record the sound of the coin. Storage - Important to enable "sharing" of try results. Disclaimer: There are no guarantees whatsoever regarding the function and accuracy of this app. There are a lot of factors which should cause this apk to report false positive or false negative results. This apk could only be used to complement another testing ways, not replace them.
