Most weather apps say the wind is from 270°. Relative Wind Compass shows you an arrow pointing where the wind is coming from, relative to where you’re standing or heading. Turn, and the arrow moves. No mental math. Built for iPhone with a paired Apple Watch app and complication.

Please include your iOS version, device model, and the activity mode you were in when the issue happened. If you can grab a screenshot of the app showing the wrong data, that helps a lot.
The arrow points where the wind is coming from, relative to where your phone is facing. Try rotating your phone — the arrow should rotate the opposite direction (it stays pointing at the actual wind source). All directions in the app are true, not magnetic, to match what pilots and the FAA use.
The app refreshes weather every five minutes, plus whenever you move more than two kilometers. Pull-to-refresh forces an immediate update. If it’s still stale, check that you’ve granted Location permission (Settings → Privacy & Security → Location Services → Relative Wind Compass → While Using).
Apple’s WeatherKit for current conditions, hourly forecast, and NWS alerts. The FAA’s aviationweather.gov for airport METARs and winds-aloft forecasts. Your iPhone’s built-in altimeter for barometric pressure (used in pressure-altitude and density-altitude math).
Winds aloft come from the FAA’s six-hourly FD forecast and are linearly interpolated between forecast layers (3,000 / 6,000 / 9,000 / 12,000 ft). Treat them as a planning tool, not a real-time measurement — they’re a forecast, not a live observation.
The watch app needs your iPhone within Bluetooth range to receive weather updates. If the watch is showing stale data, open the iPhone app once to force a sync. The complication on the watch face updates whenever the watch app receives new data.
No — weather has to be fetched live. The app will keep displaying the last reading it received, but won’t update until you’re back online.
No. There are no accounts, no analytics, no advertising SDKs, no third-party trackers. Your location is used only to fetch weather for where you are, and it doesn’t leave your device except as part of the standard WeatherKit / aviationweather.gov request. See the Privacy Policy for full details.
Short version: no account, no analytics, no third-party trackers. Location and barometer data stay on your device and are used only to fetch weather. Full policy: Privacy Policy.
