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.
Available for iPhone and iPad. Requires iOS 13.
App Watch App requires watchOS 7 or higher.
There are three simple views/modes to page through by swiping horizontally.
- GPS/Manual: let the GPS and barometer get current altitude and QNH, and just enter temperature to get PA/DA. This might be useful for en-route. Or alternatively enter all three parameters manually to calculate PA/DA for any position. This mode uses a simplified calculation without dew point. However, if you also enter a value in the dew point field, the more precise formula will be used instead.
- Single airport: select an airport from the built-in database and get its altitude calculations as well as METAR data.
- Airport list: add all your favorite airports into a list and get their current PA/DA calculations nicely listed.
A warning symbol is displayed when a DA is at higher than the user defined threshold (in app settings) of the airport’s altitude.
The app also comes with a widget that shows PA/DA of the closest 5 airports of your current position.
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 (min. 4” screen required)**
- Includes watch app to display DA at current position, user and, nearby airport list
- Page with user definable list of airports and list of nearby airports showing PA/DA**
- User definable warning indicator (threshold factor in settings)
- Today widget with PA/DA for five nearby airports**
- Sharing data via mail, message, etc.
- All units are customizable
- Dark Mode support
* Built-in barometer needs to be in device
** Internet connection required
AeroAltitude uses the free available Aviation Digital Data Service from US NOAA to get METAR data.

Apple Watch App
Current position and QNH are calculated directly on watch. Only the current outside air temperature (OAT) needs to be set on the watch by using the digital crown.
User list is the same as on iPhone and thus needs to be changed on the paired iPhone. The same applies to units.
