E6B vs E6B Flight Computer Calc
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
E6B
This app provides a comprehensive suite of aviation calculations for pilots, including weather, preflight planning, in-flight adjustments, and weight and balance computations. It also offers a wide range of unit conversions for aviation-related metrics.
- Weather calculations (pressure/density altitude, crosswind)
- Preflight planning (airspeed, heading, fuel)
- In-flight calculations (true airspeed, altitude, groundspeed)
- Weight and balance with custom aircraft profiles
- Extensive unit conversions
- Time math (add/subtract times)

E6B is a modern flight computer for iPhone and iPad — built for student E6B is a modern flight computer for iPhone and iPad — built for student pilots, instrument candidates, and working aviators who need fast, accurate calculations without fumbling with a physical whiz wheel. WEATHER • Pressure & Density Altitude — from baro setting, OAT, and field elevation • Crosswind, Headwind & Tailwind — enter wind speed, direction, and runway heading • Cloud Base & Freezing Level — AGL and pressure altitude • Hydroplane Speed PREFLIGHT • Planned True Airspeed — from CAS, pressure altitude, and OAT • Required CAS / Required TAS — reverse-solve airspeed equations • Heading & Groundspeed — full wind triangle solution • Compass Heading — with magnetic variation and compass deviation • Leg Time — solve any one of time, speed, or distance • Fuel Required & Endurance • Planned Mach Number • Time Math — add and subtract times in HH:MM:SS IN-FLIGHT • Actual True Airspeed — from CAS, altitude, and OAT • Actual True Altitude — corrected for non-standard temperature • Groundspeed — from elapsed time and distance • Fuel Per Hour — from fuel used and elapsed time • Distance Flown WEIGHT & BALANCE Build custom aircraft profiles with stations, limits, and CG envelopes. Load passengers, fuel, and cargo — E6B calculates total weight, moment, and CG in real time. Save multiple profiles for different aircraft. CONVERSIONS Bidirectional converters for: NM ↔ SM ↔ km, feet ↔ meters, °C ↔ °F, inHg ↔ mb, lbs ↔ kg, US gallons ↔ liters, HH:MM:SS ↔ decimal hours, Avgas and Jet A weight (gallons or liters to pounds), and minimum climb gradient to percent or degrees.

Every E6B calculation. Free. Offline. This does what the metal wheel in your flight bag does, without the wheel — free and offline. A KEYPAD BUILT FOR A COCKPIT Most aviation calculators hand you the system keyboard: small keys, half the form covered, a minus sign that fights you. This one has its own — big keys you can hit in turbulence, and it never rearranges what you already typed. YOUR UNITS, EVERYWHERE Altimeter setting in hPa or inHg. Speed in kt, km/h or mph. Distance in nm, km or sm. Temperature in °C or °F. Fuel in litres, US or imperial gallons. Set them once: every screen, widget and saved calculation follows, input fields included. Outside the US the app starts in hPa and litres. A converter screen adds fuel volume to weight for avgas, Jet A and mogas. FLIGHT • True airspeed: IAS to CAS to TAS and Mach, using real compressible-flow relations • Pressure altitude, density altitude and temperature-corrected true altitude • Wind triangle: true heading, wind correction angle, ground speed • Crosswind and headwind for a runway, with gusts and your demonstrated limit • Time, speed and distance — fill in any two, get the third • Fuel: burn rate, endurance, required, reserve, point of no return, equal time point • Climb and descent: rate, gradient, angle, top of descent, obstacle clearance • Turn: rate, radius, bank for standard rate, load factor, stall speed in the turn • Cloud base, freezing level and glide range • Great circle distance and initial course, true to magnetic to compass • Holding entry: direct, parallel or teardrop, and the heading to fly WEIGHT AND BALANCE Build a profile from your own aircraft's weighing report — empty weight, arms, station limits, CG envelope. Load it, and see the point plotted inside the envelope, not just a number. Tanks are loaded in gallons or litres and weighed by fuel type. No aircraft library is bundled, because two airframes off the same line do not weigh the same. CLOCKS, TIMERS AND THE SUN Zulu, local and departure-field time side by side. Flight timer that runs on the Lock Screen. Countdown with holding-leg presets. Sunrise, sunset and civil twilight for any coordinate — and the three different moments night, position lights and night currency begin. ON EVERY DEVICE YOU FLY WITH iPhone, iPad, Apple Watch and Mac. The Watch app calculates on its own — crosswind and density altitude on your wrist. Saved calculations sync over iCloud. WIDGETS Crosswind on your home runway, a Zulu clock, and density altitude at your field, on the Home Screen and the Lock Screen. FOR STUDENT PILOTS The calculations the written test expects, with the inputs and the workings on the same screen so you can see where a number came from. Exam mode hides saved history and anything that reaches the network with one switch, and leaves every calculation in place. METAR AND TAF, DECODED Paste a raw observation or forecast and read it in plain language: wind, visibility, ceiling and the flight category. The same report then feeds the calculations — its altimeter and temperature give density altitude at your field, its wind gives the crosswind on your runway. Offline, no account. CHECKED, NOT ASSUMED Every formula is verified against published references — the ICAO standard atmosphere, the FAA density altitude chart, the AIM holding sectors — and re-checked automatically on every change. FREE, AND WHAT ISN'T Every calculation and conversion: free, unlimited, forever. The one-time unlock adds unlimited METAR/TAF decoding, the analog wheel, exam mode, unlimited aircraft, unlimited history and the widgets — each free to try first. One payment, never a subscription. No ads, ever: nobody should watch a rewarded video in a cockpit. Planning aid only. Not for primary navigation. Always cross-check against your POH, your charts and your own arithmetic.

Verdict
E6B and E6B Flight Computer Calc are too close to call on the numbers: across 5 compared parameters — price, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. E6B sells 2 in-app purchases, starting at $4.99 per month and E6B Flight Computer Calc sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
