GoldWatch

The application provides real‑time updates of gold, silver, platinum and palladium prices based on the New York market close, displayed in US dollars and a range of local currencies. Users can view price charts for each metal, with options for hourly data over the past 24 hours and daily data for longer periods, and switch between weight units of grams, ounces or kilograms for conversion.

A built‑in calculator uses the current mid‑price to compute the value of a specified amount of metal, updating instantly when the metal, currency or unit is changed. The site also offers a simple portfolio tracker where users can record holdings, see profit or loss, and set price alerts, all refreshed automatically at configurable intervals.

Additional features include a world‑price overview that lists metal prices by country and currency, and the ability to add the web app to a mobile home screen for quick access. The service is experimental and focused on providing up‑to‑date market data and basic wealth‑monitoring tools.
