As a former pilot with over 1,600 flying hours, I love this app, but it needs two fixes: 1) it always starts up with altitude in meters and there should be an app setting that allows for the user to select feet or meters; and 2) it needs a "tens of thousands" pointer because Im currently at Breckenridge CO (altitude 10,049) and elevations over 10,000 feet could be misread in the ANALOG display (in this instance, it displays as 49).
