Sources we trust
Forecasts powered by Apple WeatherKit and Open-Meteo.
WeatherKit drives temperature, conditions, and forecasts. Open-Meteo handles air quality and steps in where WeatherKit data is sparse.
Questions, briefly.
Why both scales at the same time?
If you grew up with one and live with the other, you spend a small amount of mental energy converting every time you check the weather. Dual Degree removes that step entirely.
Is the app free?
Free to download. Premium features like home screen and lock screen widgets are an in-app purchase.
Where does the data come from?
Apple WeatherKit drives temperature, conditions, and forecasts. Open-Meteo handles air quality and steps in for regions where WeatherKit is sparse.
Does it work outside the United States?
Yes. Forecasts are global. Coverage matches whichever provider is strongest for your region.
What is the conversion formula again?
Fahrenheit equals Celsius times nine fifths plus thirty-two. The app does the math automatically and shows both.
Is there an Android version?
Not yet. iOS first.
