Pingcoin - Coin Ping Test análises de aplicativos para 31 de março

Worried your gold or silver coin might be fake? Counterfeit coins fool even experienced dealers — but they can't fake the sound. Pingcoin uses acoustic analysis to verify coins in seconds. Just tap your coin, record the ring, and get an instant verdict. ✓ Results in seconds — faster than any other test ✓ See exactly why a coin passes or fails ✓ 37 coins supported, more added regularly HOW THE PING TEST WORKS Genuine coins produce characteristic resonance frequencies based on their metal composition, size, density, and stiffness. Gold rings differently than tungsten. Silver rings differently than copper-nickel. Pingcoin analyzes these frequencies and compares them against verified reference values. If the frequencies match — your coin is almost certainly genuine. If they don't — you may have a fake. TRANSPARENT RESULTS Unlike other apps, Pingcoin shows you the resonance tolerance for each coin. You see your coin's measured frequencies, the expected range, and exactly how close the match is. No black box — just clear, visual verification you can trust. SUPPORTED COINS Gold (14): Krugerrand, American Eagle, Canadian Maple Leaf, Britannia, Kangaroo, Chinese Panda, Austrian Corona, and more Silver (23): American Eagle, Morgan Dollar, Peace Dollar, Maple Leaf, Britannia, Kookaburra, Philharmonic, Mexican Libertad, and more WHY TRUST THE PING TEST? The ping test has been used by coin dealers for over a century. Pingcoin brings scientific precision to this traditional method using FFT frequency analysis — the same technology used in music apps and audio engineering. Pro tip: Combine the ping test with weight and visual inspection for maximum confidence. Questions? Send feedback via the app — we read everything.
