Gold Tester

Gold Tester helps you identify materials by density using simple electronic scales, with measurement accuracy considered. It guides you through a two-step process to determine whether an item is gold, silver, platinum, or palladium, and it supports non-destructive testing of jewelry, coins, and bullion. The app also lets you save and share measurements, and works offline.

The tool covers a wide range of metals, including common non-precious alloys, provides multiple precision levels, and explains the testing process on each screen. While density testing is a strong indicator, the app notes its limits and suggests complementary methods (like XRF or touchstone tests) for final conclusions.
