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 (enter temperature manually)

- 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)

- List of user defined airports showing PA/DA calculation

- List of nearby airports showing PA/DA calculation

- Includes watch app to display DA at current position, user, and nearby airports

- 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 (not available in iOS 18 or later)
