The AIRNow iPhone 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.”

Grossly inaccurate app

As this review is being written, the sun is bright red, the air is as dark as during the solar eclipse in western Washington. This area is being hit hard by wildfire smoke from every which direction. It reeks of smoke/creosote/cooked cheese weenies. EVERYTHING is coated in a fine and coarse extremely visible ash. The air/sky is a thick dark smokers' yellow color, and this app says only 'moderately' bad air quality for the area- and that tomorrow is suppose to be 'good'. To boot, it's suppose to be at 90 today- and probably will be. We aren't expecting some kind of rain or wind change for two more days. If you run your fans or a/c, your units will get clogged with ash. I have asthma- trust me- this app is absolutely not to be trusted. I'd rate zero stars if possible.

AirNow Air Quality App.

When I downloaded this, ~ 6-1-12, it worked great! Lived it! Told all my friends about it! Used it every day until about mid-Jan. 2013 when it completely quit working. Tried reinstalling the app. To no avail. I have lung disease that is made much worse by high levels of particulate matter in the air. It's a hassle to have to go to the web site, look up Tulsa, read through the data to find out what I could get in less than a minute on the iOS app. :-((((
Please fix what is wrong PLEASE!!!
I love the website! Use it for deeper info, research etc. I NEED THE APP TO WORK! Thanks.

Great App for Running

I use this app to check the air quality (in the United States) before I run outsider. I think this is a must have app for anyone who lives in a large city, where the air is sometimes hazing and potentially full of particulates. The interface is ugly, but the app does exactly what I want to do, giving me the information I want immediately without hassle. Thanks for this app!
