What it does
Home screen widget
NewAdd a small or medium widget for the live gold spot price, today's change, and a 7-day chart — right on your home screen, in your selected currency. It refreshes through the day without opening the app.
Live spot + Today's Pulse
Spot gold updated through the trading day with a heartbeat indicator. Today's Pulse gives you a one-sentence read on what's actually moving — new highs, big moves, streaks, moving-average crosses — generated from live data. Charts from 1D through 10Y and MAX, line or dot styles, rotate for fullscreen.
ETFs, futures & miners
Live prices and history for GLD, IAU, SGOL and other top gold ETFs. Gold futures contracts. Top gold mining stocks with live quotes — a different angle on gold exposure beyond the metal itself.
Karat-aware portfolio
Holdings in oz, g, kg, dwt, tola, tael, or grain. 14K and 18K pieces priced correctly against pure gold. Live P&L per position, gifts flagged separately, and realized profit logged across every closed position.
Karat calculator
Value gold instantly by weight and karat. Every karat from 24K pure (.999 fine) down to 9K, with fineness labels at every level — built for jewelers.
Signals
Live financial news from Reuters, Bloomberg, Kitco, MarketWatch and more — each with the publisher's logo. Plus live Polymarket prediction-market odds on the macro forces moving gold: Fed rate cuts, inflation, recession risk, central-bank reserves.
Key ratios
Gold/silver ratio with adaptive timeframe (1Y, 5Y, 10Y, MAX) and dated x-axis. BTC/gold ratio for hard-money sentiment. Real Interest Rate indicator (treasury rate minus inflation expectations) — the single best macro signal for gold.
Smarter sentiment
A Bullish / Bearish / Neutral badge that blends short-term momentum, 50-day trend health, and news-headline tone into one signal — not just today's price change.
What-If calculator
See what your gold would be worth today if you'd bought at any past date. Compare returns against the S&P 500 and any gold ETF with overlay charts. Toggle between lump-sum and dollar-cost-averaging with detailed DCA breakdowns.

Frequently asked questions
What is Gold Watcher?
Gold Watcher is the iPhone app for gold investors, jewelers, and precious-metals enthusiasts. It tracks the live gold spot price, top gold ETFs (GLD, IAU, SGOL) and futures, the gold/silver ratio, prediction markets, a smarter sentiment badge, seasonal patterns, a karat calculator, and a karat-aware portfolio with realized profit tracking.
How is the gold spot price tracked?
Gold Watcher pulls the live gold spot price during trading hours 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 an immersive landscape view.
What is "karat-aware" portfolio tracking?
When you log a 14K or 18K piece, Gold Watcher prices it correctly against pure gold instead of treating it like 24K. So your gold-coin holding and your 14K bracelet sit in the same portfolio with both showing the real live value.
How does the realized profit work when I sell?
When you sell a position, record the sale price and date — Gold 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 macro forces that move gold — Fed rate cuts, inflation, recession risk, central-bank reserves — pulled into a section of the Charts tab. A market view, not a chart view.
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 — instead of just reflecting today's price change.
How does the karat calculator work?
Enter weight and karat — every karat from 24K pure (.999 fine) down to 9K, with fineness labels at each level — and Gold Watcher gives you the value at the current spot price. Useful for jewelers quoting a customer or anyone selling scrap gold.
What is the gold/silver ratio and why does it matter?
The gold/silver ratio is how many ounces of silver one ounce of gold buys. It tells precious-metals investors when one metal is historically expensive or cheap relative to the other. Gold Watcher tracks the live ratio with the historical average for context.
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 Gold Watcher subscription at $2.99 per month or $12.99 per year. Both plans come with a 3-day free trial.
Also from Artificial Igknorance: Silver Watcher for stackers and sterling, · Copper Watcher for industrial-metals investors, · Lithium Watcher for the EV market.
