Air Quality & AQI

Breathe easier. Air Quality & AQI shows what is in the air around you — right now, hour by hour, and for the days ahead — using readings from official monitoring stations near you. Open the app to one clear number and what it means for you. Scroll for the rest: every major pollutant, a forecast you can plan around, and the cleanest window to head outside. KEY FEATURES • Live AQI from the nearest monitoring station, with the station and its distance always shown — real measurements, not estimates • All six major pollutants — PM2.5, PM10, ozone (O₃), nitrogen dioxide (NO₂), sulfur dioxide (SO₂), carbon monoxide (CO) — each explained in plain language • Hourly and multi-day air quality forecast • Outdoor window: the cleanest stretch of the day to run, bike, or air out your home • Pollen levels for species currently in season, where available • Weather essentials right next to the air data • Personal guidance tuned to your health profile — what today's air means for you, and what to do about it • Alerts when air quality changes at your places, plus an optional morning briefing with the day's peak • Home Screen and Lock Screen widgets — each widget can follow a different saved place • A map of monitoring stations around you • Track several places and reorder them your way; your current location stays pinned on top • No account, no sign-up The source of every reading is shown in the app, so you always know where a number comes from. Some features are part of Air Quality Pro, an optional auto-renewing subscription. Questions or ideas?
