This application shows the current local air pressure, measured by the internal pressure sensor (if available) or a nearby weather station for which it uses your current location. Features: - the background color changes with the pressure value - the pressure is automatically updated - set a reference altitude: current altitude, sea level or custom altitude - pressure units: hPa/psi, Torr/in, atm, altitude above sea level and percent of average pressure at a reference altitude - compare with
