Height and Pressure

Height and Pressure is an application that helps you to determine in two ways the mountain altitude or the height of a building.
You have to measure the temperature and the pressure with the incorporated Smartphone sensors in two places: at the base and at the top.
You can calculate the height or the altitude using the gradient of temperature in the troposphere or the barometric formula.
If you don’t know the starting altitude at the base you can ignore it and calculate only the relative height.
