Features

Precision Performance Data

Engineered for pilots, tuners, and professionals who demand mission-critical accuracy when every foot of runway and every horsepower counts.

True Offline Independence

Leverage your device's internal barometer and GPS to get instant atmospheric data in remote backcountry strips or rural racetracks without cellular service.

Humidity-Corrected Accuracy

Go beyond standard dry-bulb approximations with high-fidelity calculations that account for humidity, providing the most precise Density Altitude and RAD possible.

Description

Instant and location accurate Density Altitude calculator/instrument app for iPhone and iPad that also finds relative air density (RAD), altimeter setting, relative humidity, specific humidity (grains/lb) and more. Super useful for pilots, especially in the backcountry. Many other uses for engine tuning, racing, sports, etc. * Seamlessly integrates weather data, GPS and your phone's onboard barometer to quickly and accurately calculate your density altitude, altimeter setting, relative air density, and more. * Takes humidity into account in all calculations, making it more accurate than the typical dry bulb approximation formula used by AWOS/ASOS, etc. * Works anywhere. Great without cellular connection as well, which makes it all the more useful in the backcountry and far away from ASOS/AWOS stations. * Location Search: Find atmospheric data (Density Altitude, etc.) at any point on Earth, from anywhere! Data Sensed and Calculated (all calculated with humidity): * Density Altitude * GPS Altitude * Temperature * Altimeter Setting * Absolute Pressure * Dew Point * Relative Humidity * Specific Humidity (grains/pound) * Air Density * Relative Air Density (RAD) * Dyno Correction 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, golfers, or anyone who needs to conveniently find their Density Altitude, Altimeter Setting, Relative Aid Density (RAD), Specific Humidity or Absolute Pressure. No ads or in-app purchases. We love feedback!
