Nu Stack vs GoldFolio: Which Precious Metals App Is Right for You?

If you're searching for a precious metals app, you've probably come across GoldFolio and Nu Stack. Both deal with gold and silver. Both have free tiers. Both look like they might solve the same problem. But once you dig into what each one actually does, they serve very different types of users.

This isn't a takedown of either app. Both are well-built products with active development. The question is which one fits the way you interact with precious metals — and the answer depends on whether you're a holder or a buyer.

What GoldFolio Does

GoldFolio (goldfolio.app) is a portfolio tracker for physical precious metals. It's available as a native app on iOS and Android, and it's designed to help you track the value of what you own.

You add your holdings — gold, silver, platinum, palladium, copper — and GoldFolio shows you the total portfolio value based on live market prices. You can see allocation breakdowns, track performance over time, and monitor how your holdings move with the market.

GoldFolio also runs an active blog covering gold price history, silver trends, and investment guides. Their app store listings are well-optimized and they've built a solid presence in the portfolio tracking space.

Where GoldFolio focuses: tracking what you already have. If you're a passive holder who buys occasionally and wants to see your total value and allocation, GoldFolio does that job cleanly.

What Nu Stack Does

Nu Stack (nustack.app) is built for people who are actively buying, evaluating, and selling precious metals — not just holding them. It started as a scrap gold calculator and expanded into a full workflow tool for buyers, stackers, pawn shop owners, and dealers.

The core is the Calculator — multi-karat gold (8K through 24K) and multi-grade silver (.800 through .999), with XRF custom purity override, buy rate controls, margin calculation, refinery payout estimation, and a Deal Gauge that visually scores every deal. Live spot prices refresh every 60 seconds.

Around the calculator, Nu Stack layers inventory tracking, a profit dashboard with breakdowns by source and metal, a seller CRM, decision logging, and receipt generation with PDF output, signature capture, and photo documentation. All of that is free.

Paid tiers add coin portfolio tracking, technical analysis (SMA, RSI, MACD with buy/sell signals), price alerts, sell and ship management, a refinery tracker, a Chrome Extension that scans five online marketplaces for deals, a dealer map, AI coin identification, and bulk import from CSV or Excel.

Nu Stack is a Progressive Web App — it runs in your browser on any device. No app store download. Your data syncs across your phone, tablet, and laptop in real time through Firebase.

The Key Difference

GoldFolio answers: "What is my collection worth right now?"

Nu Stack answers: "Should I buy this? What's my margin? How does this deal compare to my last ten? Where's my profit coming from?"

They look like competitors on the surface, but they're solving different problems for different users.

Side-by-Side Comparison

Where GoldFolio Wins

Native app experience. GoldFolio is in the App Store and Play Store. If you strongly prefer installing from an app store, that's a point in their favor. Some users simply prefer the native app install flow.

Broader metal coverage. GoldFolio tracks platinum, palladium, and copper in addition to gold and silver. If you hold those metals and want them all in one portfolio view, GoldFolio covers more ground.

Established content. GoldFolio has a larger blog library and longer track record of publishing educational content. Their SEO presence is more established.

Where Nu Stack Wins

Active buying workflow. If you're evaluating scrap deals in the field, Nu Stack's calculator with buy rate, margin, deal gauge, and receipt generation is built for that. GoldFolio doesn't have a scrap calculator at all — it's not what it's designed to do.

Marketplace deal scanning. The Treasure Hunter Chrome Extension scans Facebook Marketplace, Facebook Groups, eBay, Craigslist, and Whatnot for precious metals listings and overlays deal quality badges. No other precious metals app does this.

Business tools. Seller CRM, decision logging, profit dashboard with source-level breakdowns, refinery tracking, batch management — these are tools for someone running a buying operation, not just tracking holdings.

Cross-device flexibility. Nu Stack works identically on every device through the browser. One account, same interface everywhere, real-time sync. No feature gaps between platforms.

Technical analysis. SMA, RSI, and MACD indicators for gold and silver give active traders and strategic buyers data on price trends and timing — with the standard caveat that these are tools, not financial advice.

Which Should You Choose?

Choose GoldFolio if you're a buy-and-hold investor who acquires gold and silver occasionally and wants a clean, simple way to see what your collection is worth. You're not doing weekly scrap buys or running margins — you want a portfolio view.

Choose Nu Stack if you're actively buying and selling — scrap gold, coins, bullion, or a mix. You need to calculate deals fast, track your inventory and profit, and want everything in one tool instead of juggling a calculator, a spreadsheet, and a notes app. Especially if you're buying from multiple sources like pawn shops, Facebook Marketplace, and estate sales.

Use both if you want GoldFolio's portfolio tracking for your platinum and palladium holdings alongside Nu Stack's buying workflow for gold and silver.

The Bottom Line

GoldFolio and Nu Stack aren't really direct competitors — they serve different segments of the precious metals community. GoldFolio is a portfolio tracker for holders. Nu Stack is a buying platform for active participants. The right choice is the one that matches how you actually interact with precious metals.

Try both — they're both free to start. You'll know within five minutes which one fits your workflow.
