About this app

Gold Scanner & Purity Check is a practical utility suite designed for geology hobbyists, gold prospectors, and rock collectors. This application combines native device hardware sensor integration with classic physics mathematics to provide reliable field tools. CORE FEATURES • Magnetic Metal Scanner: Utilizes your device's built-in magnetometer sensor to detect nearby metallic anomalies and track magnetic field variations on a live graphical chart. • Gold Purity & Density Tester: Uses Archimedes' principle (water displacement) to check gold purity. Simply enter the dry weight and weight in water, and it calculates the exact density to help you spot potential fakes. • Rock & Mineral Identifier: Offers a visual reference guide to look up and classify rocks, gemstones, crystals, and minerals via photo input. •Please Note: The magnetic scanning utility requires a device equipped with an internal magnetometer sensor. Performance depends on device hardware and environmental surroundings.* AUTO-RENEWABLE SUBSCRIPTIONS Gold Scanner & Purity Check provides access to premium tools through three auto-renewable subscription plans: - Weekly Subscription - Monthly Subscription - Yearly Subscription Subscription Details & Terms: • No account registration or login is required to access or subscribe. • No free trial is offered; billing begins immediately upon confirmation of purchase. • Payment will be charged to your Apple ID account at confirmation of purchase. • Subscriptions automatically renew unless auto-renew is turned off at least 24 hours before the end of the current period. • Your account will be charged for renewal within 24 hours prior to the end of the current period. • You can manage or cancel your subscription at any time in your App Store Account Settings after purchase.
