Nu Stack vs Precious Metals Manager

Two apps, two different starting points. Precious Metals Manager is a private, detailed stack tracker for Apple devices. Nu Stack started as a scrap gold calculator and grew into a web app for buying, tracking and valuing gold and silver on any device.

Both are good at what they're built for. Here's how to tell which one is built for you.

We read Precious Metals Manager's App Store listing and website on October 19, 2026; its features are as its developer describes them, and we didn't test its paid tier. Nu Stack is our app.

Side by Side

Where Precious Metals Manager Wins

Privacy by design. No account, no ads, no tracking, and your data stays in your own iCloud. If that's your top priority, it's hard to beat.

Stack analytics. Average premium paid, dollar-cost averaging, rebalancing and an annual tax report are built in. Nu Stack tracks cost basis and profit, but doesn't offer those dedicated reports.

More metals. Platinum, palladium and copper are tracked alongside gold and silver.

Native Apple apps, including a Mac version.

Where Nu Stack Wins

Any device. It runs in a browser, so Android phones and Windows or Chromebook computers work the same as an iPhone.

The buying side. If you buy scrap, estate lots or coins from the public, the calculator, deal gauge and signed receipts cover the part of the job a tracker doesn't. See how to calculate scrap gold value.

Coin values and ID. Look up a coin's metal content, see its melt value at live spot, or identify it from a photo.

Listing scoring. The Chrome extension scores marketplace listings by melt value as you browse (Pro).

A business tier. Pawn shops and gold buyers can add seller ID records, hold periods and QuickBooks export on the Business plan.

Which One Should You Use?

Choose Precious Metals Manager if you're all-Apple, you mostly buy bullion from dealers, and you want detailed analytics and tax reports with no account.

Choose Nu Stack if you use Android or a computer, you buy from the public or online listings, or you want one tool for the calculator, receipts and your stack.

Use both if you want Precious Metals Manager's analytics on a long-term stack and Nu Stack's calculator and receipts for day-to-day buying.
