Based on Sporty’s popular handheld E6B Electronic Flight Computer, the E6B app has been designed from the ground up to make the most of iOS on the iPhone, iPad and Apple Watch, and MacOS on Apple Computers. The software is based on the tried and true formulas and algorithms developed over the years by Sporty’s team of over 50 pilots. Its pilot-friendly design makes quick work of any navigational, conversion or fuel problem and it also performs conventional arithmetic calculations. The advanced timer/clock feature simultaneously tracks Zulu, Local and Home time zones. The timer counts either up or down, and will display an alert when reaching zero. 27 AVIATION FUNCTIONS -Pressure & Density Altitude -Planned True Airspeed -Heading and Groundspeed -Compass Heading -Leg Time -Fuel Required -Crosswind, Headwind and Tailwind -Cloud Base and Freezing Level -Actual True Airspeed -Actual True Altitude -Wind Speed and Direction -Groundspeed -Planned Mach Number -Required True Airspeed -Required Calibrated Airspeed -Distance Flown -Endurance -Fuel per Hour -Actual Mach Number -Percent Mean Aerodynamic Chord (MAC) -Hydroplane Speed -Required Rate of Climb -Specific Range -Pivotal Altitude -Top of Descent -Required Rate of Descent -Glide Distance 22 AVIATION CONVERSIONS -Celsius :: Fahrenheit -Nautical Miles :: Statute Miles -Nautical Miles :: Kilometers -Feet :: Meters -Pounds :: Kilograms -Avgas Gallons :: Pounds -Jet A Gallons :: Pounds -Gallons :: Liters -Hours/Minutes/Seconds :: Hours -Climb FT/NM :: Climb Percent -Climb FT/NM :: Climb Degrees CALCULATOR -Perform basic math without having to exit the application CLOCK/TIMER -Simultaneous tracking of Zulu, Home and Local time zones -Advanced timer counts up or down and operates independently so you can perform other calculations while the timer is running -Upon reaching zero in the countdown mode, a message will display no matter what app is active – a useful feature for missed approaches, switching fuel tanks, etc.

Read full 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.

Verdict

The call

Sporty's E6B Flight Computer and Density Altitude + both sit at 4.9 stars, but that hides the real split: 88% of Density Altitude +'s written reviews are positive against 59% of Sporty's E6B Flight Computer's. Density Altitude + also leads on price ($3.99 vs $9.99). Sporty's E6B Flight Computer's advantage is update cadence (every 4 weeks vs every 4 months) and chart position (#6 vs #139). On rating, ads, in-app purchases and iOS requirement there is nothing between them.
