This is one of my (few) major issues with the Windy mobile apps. It's correct on the desktop site (with the toggle switch for "1h forecast"). On the mobile app it labels the opposite of what it's showing, whereas the other items on the bottom of the forecast show the current setting such as the forecast model.
I don't think the two toggle switches is a good alternative. The single toggle from the desktop is better than that. But just labeling it as what's currently shown would be perfectly acceptable.
Please, @MarkNagy?
