Relative Wind Compass vs Window Air

THE WIND, RELATIVE TO YOU. Most weather apps tell you the wind is from 270°. Relative Wind Compass shows you an arrow pointing where the wind is coming from, relative to where you're facing right now. Turn, and the arrow moves. Cross-reference with your runway, your treestand, your firebreak, your launch site, no mental math. Built by a student pilot for anyone who needs the wind on the ground. NINE MODES, ONE ARROW • BASIC — Just the wind. Direction, speed, the relative arrow. Nothing else. • FLIGHT — Headwind and crosswind components for any runway. METAR plus winds aloft, density altitude, Zulu time, heading bug. • HUNTING — Scent-direction compass, sunrise countdown, moon phase, still-air indicator, wind-shift alerts. • BURNING — Fire-spread direction, gust delta, relative humidity and temperature, a tap-to-copy dispatch radio call, and a red banner when conditions move out of prescription. • SAILING — Apparent wind when you're moving, Beaufort force, point of sail, veer/back detector. • DRONE — Go / Caution / No-Go from your aircraft's wind and gust limits. DJI, Skydio, and Autel presets built in. • FREE FLIGHT — Flyable / Marginal / No-Fly status, optional launch-direction alignment for paragliders and hang gliders. • HOT AIR BALLOON — Winds-aloft layers (3k, 6k, 9k, 12k ft) shown directly. Steering hints when the layers diverge. • MARINE — Beaufort plus sea state, small-craft, gale, and storm advisories. APPLE WATCH The full relative-wind dial on your wrist. A complication for the watch face so you can glance at the wind without unlocking your phone. The watch and phone keep each other in sync. IPHONE DUO Unfold it and the arrow gets half the screen, with speed, gusts and your mode's details on the other half. Half-fold it like a laptop and the arrow stands up top. Closed, the cover screen shows the compass you know. WEATHER YOU CAN TRUST Live surface conditions come from Apple's WeatherKit. Airport METARs and winds-aloft forecasts come from the FAA's aviationweather.gov. Barometric pressure reads from your iPhone's built-in altimeter. Everything is true-referenced, not magnetic. ALERTS, FORECAST, FEELS-LIKE Active National Weather Service alerts, Red Flag warnings for burn crews, Small Craft Advisories for sailors, severe-weather alerts for everyone — surface at the top of every screen. A one-hour wind forecast lives next to the live reading. Wind chill and heat index update with the data. YOUR UNITS, YOUR CALL Knots, mph, or m/s. Feet or meters. Zulu or local time. Cardinal points or true degrees. Set it once. PRIVACY No account. No tracking. No analytics. Your location stays on your device, it is used only to fetch weather for where you are. For pilots, hunters, prescribed-burn crews, sailors, drone operators, paraglider and hang glider pilots, balloon crews, and anyone on the water. For anyone who needs to know where the wind is coming from, relative to where they're standing, without doing the geometry in their head.

Should you open your windows right now? Window Air turns live outdoor air quality into one clear answer - OPEN, VENT, or KEEP CLOSED - based on your local conditions and your sensitivities. You crack a window for fresh air and let in pollen. You keep it shut on a beautiful day when the air outside was actually clean. The data exists - AQI, PM2.5, pollen, wildfire smoke, humidity - but reading five dashboards every morning is nobody's routine. HOW IT WORKS 1. Set your sensitivities: pollen, smoke, dust, or general air quality. 2. Window Air pulls live outdoor air data for your location. 3. You get a single verdict - OPEN, VENT, or KEEP CLOSED - with the reason and the best time window today. It takes 20 seconds to set up. No account required. CORE FEATURES Today's Verdict A single answer plus the why - current AQI, dominant pollutant, pollen level, and humidity, read at a glance instead of buried in charts. Best Window Today See when outdoor air is cleanest so you can air out your home at the right hour. Air Quality Breakdown PM2.5, PM10, ozone, pollen, and humidity in one simple view, with plain-language levels instead of raw numbers. PRO FEATURES Upgrade to Pro for deeper insights: - Multi-room profiles with different sensitivities - Hourly air quality forecast and verdict timeline - Wildfire smoke and pollen surge alerts - 7-day history and trend tracking - Custom threshold levels per pollutant - Push notifications when it's safe to open or time to close PRIVACY FIRST - No account, no login - All data stored locally on your device - Location is used only to fetch outdoor air quality data, never stored on any server - No tracking, no ads, no third-party analytics Window Air provides general air quality guidance based on public environmental data.
