EPA's AIRNow Apk v2.1.0  

The AIRNow Android application will provide an increasingly mobile public with real-time air quality information that people can use to protect their health when planning their daily activities

The app will allow users to get location-specific reports on current air quality and air quality forecasts for both ozone and fine particle pollution (PM2.5). Air quality maps from the AIRNow website provide visual depictions of current and forecast air quality nationwide, and a page on air quality-related health effects explains what actions people can take to protect their health at different AQI levels, such as “code orange.”
