FAQ
Why show both scales at the same time?
If you grew up with one scale and live with the other, you spend a small bit of mental energy converting every time you check the weather. Dual Degree removes that step entirely.
Is the app free?
Yes. Free to download, no subscription, no ads.
Where does the data come from?
Open-Meteo drives temperature, conditions, and forecasts, with Apple WeatherKit as the backup source and the provider of severe weather alerts and minute-by-minute precipitation. Lightning detections come from NOAA's GOES Geostationary Lightning Mapper.
When does the Lightning card show up?
When at least one strike has landed within 50 km of the selected city in the last 30 minutes. The card shows the closest strike and the count for the window. Tap the corner bolt for a full-screen map of every recent strike, with coordinates, address, and a one-tap handoff to Google Maps or Apple Maps. Coverage today is the Americas and adjacent oceans, sourced from NOAA's GOES satellite lightning data.
Does it work outside the United States?
Yes. Forecasts are global. Coverage uses whichever provider is strongest for your region.
What languages does the app support?
Ten: English, Spanish, German, French, Italian, Portuguese, Japanese, Korean, Simplified Chinese, and Greek. The app follows your iOS language by default; you can override it inside the app.
My current location is wrong or the weather isn't updating.
First, pull-to-refresh on the main screen. If that doesn't help, check that Location Services is enabled for Dual Degree in iOS Settings → Privacy & Security → Location Services. For widgets, removing and re-adding the widget often unsticks a stale timeline.
Is there an Android version?
Not yet. iOS first.
