One thing that I'm noticing with the app is something I experienced from my days of DVD programming. It is not clear which mode is currently active with the toggle buttons. It is not obvious if the flag is showing you the current mode or if the button needs to be pressed to get the indicated mode. To toggle the weather, do you click the clouds to show cloudy mode or to view clear view or vice versa. It almost feels inverted to me.
I'm also having the same issue on a current project. There's a set of +/- buttons that control the size of a time range window. Clicking the +/- buttons increase/decrease the size of the window, but for the start time + makes the time seconds value smaller, and - makes the seconds value larger. For the end value, it is exactly the opposite. But for the window size, both sets of buttons do what one expects. So it's a matter of perspective that needs to be clear to the user.
