About this app

* Seamlessly integrates OpenWeatherMap, MET Meteorologisk institute, Amazon weather data, GPS and phone's onboard sensors to quickly and accurately calculate your air density, density altitude and rest very useful for tuners and aviators data

* Works great without cellular connection or barometer

* Сan work without access to your current location (we care about your privacy), you can manually select any place in the world on google map and get data for this place

This app provides:
- Air Density
- Density Altitude
- Relative Air Density (RAD)
- Dew Point
- SAE - Dyno Correction Factor
- SAE - Relative Horsepower
- Station Pressure
- Saturation Vapor Pressure
- Virtual Temperature
- Actual Vapor Pressure
- Cumulus Cloud Base Height
- Dry Air
- Dry Air Pressure
- Volumetric Content of Oxygen
- Oxygen Pressure

This app can obtain automatically the position and altitude to get the temperature, pressure and humidity from the nearest weather station thought internet. If more accuracy is needed, a portable weather station can also be used. Application can run without GPS, WiFi and internet. If you're in internet range, you don't need to supply any data. If you're out of internet range, all you need to supply is the outside air temperature.

Great tool for pilots, drag racers, engine tuners, or anyone who needs to conveniently find their Air Density, Density Altitude, Dyno Correction Factor and rest of calculated data.

No ads or in-app purchases.

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

• Results: In this tab are shown:
- Air Density
- Density Altitude
- Relative Air Density (RAD)
- Dew Point
- SAE - Dyno Correction Factor
- SAE - Relative Horsepower
- Station Pressure
- Saturation Vapor Pressure
- Virtual Temperature
- Actual Vapor Pressure
- Cumulus Cloud Base Height
- Dry Air
- Dry Air Pressure
- Volumetric Content of Oxygen
- Oxygen Pressure

In addition, the parameters used for the calculations are showed (time, temperature, humidity, pressure and altitude).

• History: This tab contains the history of all calculating data. If you change the weather, the new data will be saved in history.

• Weather: In this tab, you can set the values for current temperature, pressure, altitude and humidity.
Also this tab allows to use the GPS to get the current position and altitude, and connect to an external service (you can choose one weather data source from several possible) 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 for pressures.

ERRORS AND SUGGESTIONS:
If you have any doubt about using this App, please, contact us. We answer every question, and we take care of all comments from our users to try to improve our software. We are also users of this application.

PERMISSIONS:
The application may needs the next permissions:
- Your location: it lets the application get the position and the altitude using the GPS to know which is the nearest weather station.
- Storage: it's used for storing the config preferences.
- Network communication: to invoke the external service which provides the current weather conditions

New features

• New feature: Weather for custom location. You can manually select any place in the world and all data will be calculated for it (for altitude and current weather conditions in this place)
• Improved functionality for the feature 'Weather for custom location'. We added a search bar where you can enter the location name. Search places easier and faster now
• We reworked the altitude determination algorithm for the 'weather for custom location' feature
