What's New in Pingcoin

1.0.9

October 23, 2026

New coins, free to test: some coins now have frequencies predicted by our resonance model rather than recorded. They're marked FREE in the coin list, testing them never uses a ping, and your tests help us fine-tune them. Personal help: in the menu, "Feedback & support" lets you tell me what's going on, and I'll reply by email. Fixes: the coin list now loads even if one coin's data is incomplete.

The Most Essential IOS App for Beginner Gold & Silver Collectors

This is the best piece of IOS technology that I’ve encountered since I started collecting a little over a year ago. XRF Guns are expensive, I’m not smart enough for a Negative Gravity test and and driving to the Gold & Silver Exchange to authenticate every little coin in my collection becomes a cumbersome chore. I always feel like I’m annoying the dealer because I’m not there to buy or sell. This app is not a perfect tool with indisputable reliability but it is an extremely effective first line of investigation before getting an official XRF/Sigma Test analysis completed.
