* Seamlessly integrates Forecast.io weather data, GPS and your phone's onboard barometer to quickly and accurately calculate your density altitude.
* Works great without cellular connection or barometer as well.
The quickest way to get your Density Altitude! On the iPhone 6/6+ and newer iPads, it will use the built-in barometer and GPS. If you're in cell range, you don't need to supply any data. If you're out of cell range, all you need to supply is the outside air temperature. Designed not to need an internet connection, so it will work anytime and anywhere you need it.
Great tool for pilots, drag racers, engine tuners, or anyone who needs to conveniently find their Density Altitude, Altimeter Setting or Absolute Pressure.
No ads or in-app purchases.
Note: In order to not require an internet connection, Density Altitude+ uses the dry air approximation formula, which is the same formula used by ASOS/AWOS-3 automated weather stations at US Airports. Please be aware that this formula may underestimate the Density Altitude in more humid environments.
