AeroAltitude calculates pressure altitude (PA) and density altitude (DA) either from user data inputs or automatically by using built-in GPS, built-in barometer*, and METAR** of airports.

Overview of features:
– PA/DA/QNH calculation for current position using GPS and barometer *
– PA/DA calculation based on user inputs for altitude, QNH, and temperature
– PA/DA calculation of any airports from the built-in airport database. Including METAR display and chart of DA (on 4” screens and higher) **
– Includes watch app to display DA at current position and nearby airports ***
– User definable list of airports showing PA/DA calculation **
– List of nearby airports showing PA/DA calculation **
– User definable warning threshold factor
– Sharing data via mail, message, etc.
– All units are customizable
– Pre iOS 14 today widget with PA/DA for maximum five nearby airports **

AeroAltitude uses the freely available Aviation Digital Data Service from US NOAA to get METAR data.
