I found this product on Amazon that purports to use your iPhone to test for Gold and Platinum
GemOro AuRACLE AGT2 Electronic Mobile Gold/Platinum Tester Kit For Apple iOS iPhone/iPad/iTouch
https://www.amazon.com/gp/product/B008DID5Z8/
I can only guess it somehow work on electrical resistance, if it does in fact work.
