WeatherDuo

Weather for people who think in two units.

WeatherDuo shows every temperature in both Fahrenheit and Celsius, at the same time, everywhere in the app. No toggling. No mental math. No wondering whether 25° means a sweater or a swim.

BUILT FOR • Immigrants and expats who grew up with one unit and live with the other • Travelers crossing borders • Families and friends spread across countries • Anyone who reads the news in one system and the weather in another

BOTH UNITS, EVERYWHERE • Current conditions with the unit you choose shown larger • Hourly forecast for the next 24 hours • 10-day forecast with temperature range bars • "Feels like", dew point, highs and lows, all in both units

MADE FOR LIFE ACROSS BORDERS • Local time for cities in other time zones • "4°F · 2°C warmer than your location" comparisons • Plain-language guidance like "Cool. Bring a jacket." • A built-in converter with familiar reference points

THE DETAILS • Next-hour precipitation chart where available • Severe weather alerts from local agencies where available • Humidity, wind, UV index, pressure, visibility, sunrise and sunset • Wind, pressure and visibility in your region's units

WIDGETS AND SIRI • Small, medium and large Home Screen widgets • Lock Screen widgets • Ask Siri: "What's the weather in WeatherDuo"

PRIVATE BY DESIGN No account. No ads. No tracking. Your location is used only to fetch your forecast.
