GoFly is a flight computer for iOS built for the person learning it. Watch the wind triangle come alive as you type, then unfold any result into the step-by-step math behind it.
Free to try, 5 flights on us. No account, no ads.
Features
Eight tools, each designed to make the invisible visible instead of handing you a number from a black box.
A cockpit-style instrument that redraws heading, track, and wind vectors as you type. See the crab angle, not just its value.
Every result unfolds into the formula, the plugged-in values, and each step. Learn it once, then collapse it away.
True airspeed and density altitude, time-speed-distance, fuel and endurance, crosswind components, and unit conversions.
Fetch any airport's live report from the NOAA Aviation Weather Center and read it in plain language, line by line.
Load your aircraft and watch gross weight and CG plotted against the envelope. Save your airplanes as reusable presets.
A purpose-built keypad with explicit units on every field, so knots never quietly mix with mph.
Every calculation runs on the device, no signal needed. Fetching a live METAR is the only tool that requires a connection.
No accounts, no analytics, no ads, no data collection. Your numbers stay on your device.
Made for student pilots in ground school and for CFIs who want a clean way to demonstrate the concepts.
