Air Pressure - New App for iPhone, iPad and Android

Air Pressure shows the current local air pressure (in hPa/psi, Torr, atm, altitude above sea level and percent of average pressure at a reference altitude), measured by the internal pressure sensor (if available) or a nearby weather station for which it uses your current location. The background color changes with the pressure value.

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, atm, altitude above sea level and percent of average pressure at a reference altitude
• compare with reference pressure at a reference altitude
• the location is automatically updated when you move
• metric and imperial units
