Where can I fly today — or tomorrow? Pick a leave time. Flybound draws wind-shaped range rings around your home airport and scores every reachable field GO, CAUTION or NO-GO — from live weather, your aircraft's numbers, daylight, fuel and your own personal minimums. Then it does the part a raw briefing never does: it tells you what would change the answer. IT TELLS YOU WHY — AND WHAT WOULD FIX IT Every CAUTION and NO-GO carries the number: "GO if the ceiling lifts 400 ft." "GO if you leave by 2:15 PM." Trend arrows show whether the ceiling and visibility are lifting or dropping, and when they're heading your way you get a time: "on this trend, around 2:40 PM." YOUR MINIMUMS, NOT SOMEBODY ELSE'S Ceiling, visibility, surface wind, gusts, crosswind, density altitude, runway length, fuel on the field, your own night policy. PLAN TONIGHT FOR TOMORROW Tap Tomorrow 8 AM or 1 PM, or set any leave time, and every airport is scored on its forecast for when you'd arrive. Where the forecast doesn't reach yet, Flybound says so instead of guessing green. THE WHOLE DAY, NOT JUST THE DEPARTURE • Weather along the route at the time you will actually cross it, not only at the ends. • The forecast at your arrival, and again for the ride home. • Last light, and the be-home-by deadline that follows from it, with night-currency cues. • A fuel-stop planner that sizes the stop and lands it near the true midpoint. • Round-trip or one-way scoring, and an expected-ride estimate for the passenger who asks. ALTITUDE Trips are planned at the altitude you actually fly, legal for each direction, with the climb modelled. Pro adds a cruise-altitude card: the wind triangle solved at every legal level your aircraft can reach, out and back. WHEN YOU KNOW BETTER THAN THE DATA Set a field aside — a runway you won't use, a sensor you don't trust — and Flybound leaves it out of every decision: as a destination, as en-route weather on other routes, as a weather source for its neighbours, and as a fuel stop. With Pro, it can also leave out the ~135 airports where Vector Airport Solutions bills landing and ramp fees; put any one back with a tap. ON THE GROUND AND AFTER Runways with wind components, frequencies, airspace class, fuel, and things worth walking to. A Wheels Down log of everywhere you've been, scout alerts for the fields you care about, and a home-screen widget. IPHONE, IPAD AND MAC On iPad and Mac the map, the airport list and the brief sit side by side. One purchase covers every device on your Apple ID, and your aircraft, minimums and logbook follow you through iCloud.

It is not a navigation or in-flight app, it carries no terrain data, and it is not a substitute for an official preflight briefing. Verify weather, airspace, runways, frequencies, fuel and NOTAMs against current official sources before every flight.
