I’m British, my wife’s American. We live in the US. For years, almost every day, we have the same dance around the weather... “Yes, but that’s in °C”... “ok, so what is that in °F?”… So I made a little weather app. That always shows °C and °F together. No switching settings. No mental maths. Clean, minimal design with no ads. Felsius gives you instant clarity at glance.
