MyAirQuality

Air quality conditions vary significantly by location, season, and daily conditions. To reduce the very large health impact of poor air quality, hundreds of communities measure and forecast air quality. This allows people to take protective measures when air quality is or is expected to be poor.
MyAirQuality is a free iPhone/iPod Touch/iPad application that displays air quality observations, forecasts, and health messages for locations you select in the U.S.. The application displays air quality conditions (obtained from AIRNow) using the same criteria and formats as Federal, tribal, state, and local governments use.
MyAirQuality includes documentation to help you understand the air quality information it reports and provides links to more detailed information. View the documentation by touching “?” in the application. The application contains no advertisements.
