ProvCheck vs Sterling

The ProvCheck app allows you to verify the authenticity of your bullion by taking a photograph of its surface. You will also be able to view the origin and carbon footprint of the gold in your bullion.

Sterling is a precious-metals stack tracker built for silverbugs and goldbugs who hold physical bullion for the long haul. Log every pickup - coins, bars and rounds - and Sterling does the math that matters to a stacker: - Melt value of each holding at the latest available spot - Premium you paid over spot, and how much of it you are still carrying - Where the whole stack sits right now, up or underwater, in your chosen currency - Break-even spot per item, with the dealer spread baked in, so you know where spot needs to sit to sell back whole WHY STACKERS LIKE IT - It speaks your language: stack, pickup, melt, premium, AGW and ASW. - Every figure traces back to what you actually paid, down to the fees. - Record a sale, set the dealer spread, and see your realized P&L. - Track in USD, CAD, GBP, AUD and more; switch the display currency any time without touching your records. PRIVATE BY DESIGN - Fully offline. No account, no sign-in, no backend. - No ads and no trackers. The only network activity is an optional spot-price refresh. - Your stack lives on your device and, if you choose, syncs only through your own private iCloud.
