Thank you for using Flight Calcs. Your attention to fuel, weather, loading and timing is good airmanship. Keep useful numbers close from preflight to the debrief, with aviation calculators, airport references and saved records on iPhone and iPad. FLIGHT PLANNING AND E6B - Solve heading, wind correction angle, groundspeed, time and distance. - Practice with the visual mechanical E6B simulator. - Check runway crosswind, headwind and tailwind components. - Estimate trip fuel, reserve fuel, endurance, climb and descent. - Calculate true airspeed, Mach, pressure altitude and density altitude. - Review cloud base estimates and holding pattern entry guidance. - Build NavLog legs with checkpoints, ETA, fuel and route notes. - Convert knots, nautical miles, gallons, liters, pounds and more. WEIGHT AND BALANCE - Choose from eleven searchable aircraft planning templates. - Enter occupants, baggage, equipment and usable fuel by station. - Compare zero-fuel, ramp, takeoff and landing weight and CG. - Include ground or taxi burn and trip fuel burn. - Switch between Load, Sheet and Envelope views. - Review basic empty weight, station arms and moments. - See which checks apply when a phase weight maximum is unknown. - Save loading snapshots alongside your other flight records. Templates are starting points. Verify the current aircraft's basic empty weight, station limits, fuel assumptions and CG envelope against its approved documents. AVIATION WEATHER AND AIRPORTS - Retrieve METAR and TAF reports from AviationWeather.gov. - Decode wind, visibility, clouds, altimeter and flight category. - Review TAF changes in a forecast timeline. - Decode pasted NOTAM and SNOWTAM reports. - Compare plain-language summaries with the original reports. - Find nearby airports and weather when you request location. - Search bundled airports by identifier, name, city or region. - Review available runways, elevation, frequencies and time zones. - Browse FAA reference material for preflight and study.

Verdict
The clearest difference is rating: Flight Calcs at 5.0 against 2Go's 4.0. Flight Calcs also leads on monetization model (free vs paid). 2Go's advantage is review sentiment (100% vs 85%) and update cadence (every 4 weeks vs every 2 months). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Flight Calcs sells 2 in-app purchases, starting at $1.99 per month and 2Go sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
Flight Calcs holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 1 and 4 respectively. Written reviews complicate that: 85% of Flight Calcs's written reviews are positive against 100% of 2Go's, so the app with the better star average is not the one people write more warmly about.
Flight Calcs ships an update every 2 months, 2Go every 4 weeks. The most recent releases landed on October 23, 2026 and October 19, 2026 respectively.
