About this app

Air Quality Tracker shows you what you are actually breathing — right now, where you are, and for the week ahead.

REAL-TIME AIR QUALITY INDEX
Open the app and see your local air quality index on one colour-coded dial, with a plain verdict: good, moderate or unhealthy. AQI readings come from Google's air quality service and from the World Air Quality Index project, which aggregates thousands of monitoring stations worldwide.

POLLUTION BREAKDOWN: PM2.5, PM10, OZONE, NO2
See the pollutants behind the number. Fine particulate matter (PM2.5), coarse particulate matter (PM10), ozone (O3) and nitrogen dioxide (NO2) each get a concentration, a unit and a position on the EPA scale — so smog, haze and dust days are not just a colour.

INTERACTIVE AIR POLLUTION MAP
Pan and zoom a live pollution heat map of your region. Switch between the US AQI layer and a PM2.5 layer to see how air quality changes street by street and district by district.

7-DAY AIR QUALITY FORECAST
Check the days ahead before you plan a run, a commute or an afternoon outside. A 24-hour chart shows how the index rises and falls through the day so you can pick your moment. Where a station publishes no multi-day forecast, the app says so and labels its estimate instead of passing it off as official data.

MAJOR CITIES AT A GLANCE
Compare air pollution in 29 major cities worldwide and across Europe, ranked worst air first — useful before a trip, or to keep an eye on where family lives.

HEALTH GUIDANCE
Every reading comes with a recommendation for the general population, taken from the air quality service rather than written by us.

DAILY AIR QUALITY ALERTS ON YOUR TERMS
Set your own thresholds on a 0-100 air health scale and get at most one "poor air" and one "good air" notification per day. No spam, no push server, nothing sent to a third party — alerts are generated on your device.

HOME SCREEN WIDGET
Add the widget and see the current AQI for your area without opening the app.
