EPA's AIRNow

US Environmental Protection Agency

About this app

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.”

Ratings and reviews

Pretty happy with it so far. I live in the Pacific NW with a lot of wildfires so keeping up is important. This app is super easy to use. No ads, free, clean layout. I have not noticed huge map/home discrepancies some people have pointed out. Recommend.

Doesn't give real time data? I don't know. The website data is always several hours delayed. This doesn't give a time stamp of when it was last updated. Also doesn't let me see nearest monitors, and I'm in between several. Useful for doing a quick check of different places I'm traveling to though. But the website is probably easier to use, although much slower loading. And then load again to get actual monitor location data... So slow.
