Air Pressure App

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 reference pressure at a reference altitude

- the location is automatically updated when you move

- metric and imperial units

- supports the iPad multitasking (split view,...)
