What it does
Live spot price + heartbeat

Copper ETFs & futures
Live prices for CPER, COPX, COPP and other top copper ETFs, plus futures contracts. Daily changes and full price history alongside spot.
Dr Copper signal
A live read on copper's relationship to the S&P 500 — the classic "Dr. Copper" indicator that has predicted recessions and recoveries. Plotted so you can see when copper is leading or trailing the market.
Scrap calculator
Value copper by weight and purity instantly. Built-in grades from OFHC lab grade (100%) down to #2 copper scrap (95%), with labels for every commercial level.
Portfolio with realized P&L
Holdings in oz, g, kg, lb, or tonne. Live P&L per position, gifts flagged separately, and realized profit logged across every closed position when you record a sale.
Prediction markets
Live Polymarket bets on the forces driving copper — China manufacturing, data-center buildout, industrial production, recession risk — pulled into a section of the Charts tab.
Smarter sentiment
A Bullish / Bearish / Neutral badge that blends short-term momentum, 50-day trend health, and news-headline tone into one signal.

Frequently asked questions
What is Copper Watcher?
Copper Watcher is the iPhone app for copper investors, scrap dealers, electricians, and metal traders. It tracks the live copper spot price, top copper ETFs (CPER, COPX, COPP) and futures, prediction markets, a smarter sentiment badge, the Dr Copper signal vs the S&P 500, a scrap calculator, and a portfolio with realized profit tracking.
How is the copper spot price tracked?
Spot copper updates throughout the trading day with a live heartbeat indicator. Historical charts cover 1D, 1W, 1M, 3M, 1Y, 5Y, and ALL. Switch between line and dot chart styles, or rotate your iPhone for immersive fullscreen charts.
What is the Dr Copper signal?
"Dr. Copper" is the old market nickname for copper's ability to predict the broader economy — when copper turns, the S&P 500 often follows. Copper Watcher gives you a live read of that relationship, plotted so you can see when copper is leading or trailing the market.
How does the realized profit work when I sell?
When you sell a position, record the sale price and date — Copper Watcher logs the realized gain and rolls it into a running cumulative profit across all of your closed positions. Gifts can be marked separately so they don't inflate the profit number.
What are Prediction Markets?
A live read of Polymarket bets on the forces driving copper — China manufacturing, data-center buildout, industrial production, recession risk — pulled into a section of the Charts tab.
What does the Smarter Sentiment badge do?
A Bullish / Bearish / Neutral indicator that blends short-term price momentum, the health of the 50-day trend, and the tone of recent news headlines into one signal.
How does the scrap calculator work?
Enter the weight and pick the copper grade — from OFHC lab grade (100%) down to #2 copper scrap (95%) — and Copper Watcher gives you the value at the current spot price. Built-in labels for every commercial purity level so you can quote a customer instantly.
Can I track my own copper holdings?
Yes. The portfolio tracker manages holdings in oz, g, kg, lb, or tonne. Track purchase price, live P&L per position, and the running realized profit on closed positions. Mark gifts separately so they don't inflate the profit number.
What currencies are supported?
Ten: CAD, USD, EUR, GBP, INR, AUD, CHF, JPY, CNY, and HKD. Pick one and the entire app switches.
What does Premium cost?
Free to download. The Portfolio, What-If, and Calculator tabs are unlocked with a Copper Watcher subscription at $1.99 per month or $4.99 per year. The yearly plan comes with a 7-day free trial.
