Barometer Altimeter Widget

A simple yet useful barometric altimeter that actually works. Meant only for devices that have a built in barometer or pressure sensor. Computes your altitude from barometric pressure using the standard atmosphere model. Can be easily calibrated with a known altitude. Calibrate as the weather and your location changes for best results. Displays altitude above sea level in feet or meters. Displays pressure in millibar, kPA, psi, mm of Hg, or inches of Hg. Includes a Widget for your home screen or lock screen. Uses barometer only, does not use GPS or other location services. Optimized for outdoor use.
