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

Overview of features:
- PA/DA calculation for current position using GPS and QNH input
- 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
- 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

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