I just realized this week that the iPhone barometer cannot differentiate steps walked up a certain number of floors vs taking an elevator. The health app always displays 'floors climbed' to reflect the numbers of floors I ascend in an elevator. This is obviously misleading, since one is not actually walking up a flight of stairs, rather taking a ride in an elevator. Does anyone know of any apps that can help differentiate steps taken vs floors ascended on an elevator? For example, if I work on the top floor of the John Hancock building in Chicago and take the elevator, I don't want my Health App to say I 'climbed' 100 floors!
