Stack Tracker is a private, beautifully designed app for tracking your precious metals collection — gold, silver, platinum, palladium, copper, and rhodium. Whether you stack bullion coins, bars, rounds, hand-poured pieces, junk silver, or graded numismatics, Stack Tracker keeps your whole stack organized and valued in one place.

PRIVATE BY DESIGN
No accounts. No analytics. No tracking. No ads. Everything you enter lives only on your device. Optional live spot prices are off by default and, when enabled, send nothing about you or your collection.
