Sporty's E6B Flight Computer vs WhatTheFreq

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.

WhatTheFreq is a fast flight scratchpad for pilots who want airport frequencies, weather, runway wind context, and quick notes in one place. Enter a route and load the airports you care about in seconds. WhatTheFreq organizes key airport frequencies into clean, easy-to-scan cards so you can quickly reference ATIS, clearance, ground, tower, CTAF, UNICOM, approach, departure, and ASOS/AWOS data without bouncing between tabs or apps. The app also pulls METAR data and turns it into practical at-a-glance guidance. See flight category, wind, visibility, ceiling, and best-runway context with estimated headwind and crosswind components for available runway headings. WhatTheFreq is built for real cockpit workflow: • Load multiple airports in a route • View FAA airport frequency data in a simple card layout • Check live METAR conditions • See VFR, MVFR, IFR, and LIFR status at a glance • Compare runway wind components • Add your own temporary frequencies • Keep scratch notes for remarks, taxi routes, and clearances WhatTheFreq is designed as a lightweight pilot companion for quick reference and situational awareness. Not for primary navigation. Always verify frequencies, weather, and operational information with official sources and current procedures.
