Aer: Air Quality

Live air quality and a 7-day AQI forecast for 35 cities across North Macedonia — with plain-language advice on when it's safe to be outside.

Aer makes the air in North Macedonia easy to understand and act on.

See the current European Air Quality Index (AQI) for 35 cities, a plain-language verdict — "great day to be outside" or "limit heavy outdoor activity" — and a 7-day AQI forecast so you can plan ahead: the school run, a training session, when to open the windows.

WHAT YOU GET • Live AQI and pollutant levels (PM2.5, PM10, NO₂, O₃) for 35 cities • A 7-day AQI forecast from the Copernicus (CAMS) atmospheric model • Your nearest city, selected automatically from your location (or pick one manually) • Health guidance tailored to your profile — general, respiratory-sensitive, or active • A colour-coded map, city comparison, saved cities, and AQI alerts • Home Screen and Lock Screen widgets, plus a Live Activity for pollution spikes • A clear "what to do now" layer: walk, ventilate, mask, or take it easy • Learn section explaining what AQI and each pollutant mean • Works offline — the last readings stay available, always clearly labelled • Available in English, Macedonian, and Albanian

HONEST BY DESIGN Aer's data comes from the Copernicus (CAMS) atmospheric model via Open-Meteo. Values are modelled estimates and forecasts, not readings from a physical sensor at your exact location, and the app labels them as such. Health guidance is general information, not medical advice — if you have a medical condition, follow your doctor's guidance.

Aer is free, with no ads and no tracking. Your location is used only to pick the nearest city and never leaves your device.
