A weather app for iPhone and iPad
Both scales,
side by side.
Twofold Weather shows the actual and feels-like temperature in Celsius and Fahrenheit together, so there is nothing to convert. Old or forecast-based readings are flagged, and the Weather data and sources page names each provider and reading time.
iPhone and iPad / iOS 18 or later
