This app provides the air density, density altitude, relative air density, dew point and relative horsepower. The input data can be automatically obtained from the GPS and the nearest weather station or manually introduced.

The application is made up of three tabs that are described next:

- Results: In this tab, the calculated air density, density altitude, relative air density (RAD), dew point and relative horsepower are shown. In addition, the parameters used for the calculations are showed (time, temperature, humidity, real and normalized pressure and altitude).

- Weather: you can set the values for current temperature, pressure, altitude and humidity. The values of this screen can be manually set or can be loaded by the application reading the data from the nearest weather station (from the GPS tab).

- GPS: This tab allows to use the location service (using GPS or WiFi) to get the current position and altitude, and connect to an external service to get the weather conditions of the nearest weather station (temperature, pressure and humidity).

The app let you use different measure units: ºC y ºF for temperatures, meter and feet for altitude, and mb, hPa, mmHg, inHg y atm for pressures.
