Air pollution can be a problem anywhere, not just in areas of high population or industry. That is why there are over 2,600 EPA air quality stations across North America. It is important for people everywhere to easily find and understand air pollution levels. Unfortunately, most people remain unaware of their local air quality because the data is not accessible or approachable. Air Lookout aims to change that.
Please Note: Air Lookout currently only supports the U.S. Environmental Protection Agency's air quality stations in North America.
• Hourly reports of air quality from the closest monitoring station.
• Know when it is safe to exercise outside.
• Provides a two day forecast (where supported).
• Explore all reporting air quality stations on a map.
• See a ranking of the best and worst cities in North America
• Monitors PM2.5, PM10, Ozone, Nitrates, Sulfides, Carbon Monoxide and more (12 pollutants can be monitored from supporting air quality stations).
• Shows the Air Quality Index in official EPA levels that are easy to understand.
• Provides simple and concise definitions of all pollutants and air quality terms.
• Uses the EPA color coding for the Air Quality Index.
Includes Apple Watch app, Glance and Today Widget.
Access to over 2,600 air quality stations
• 2,367 air quality stations in the United States
• 225 air quality stations in Canada
• 33 air quality stations in Mexico

Thought It Was Good
I love the layout and idea of this app, but I lost faith in it these last few days during the Woolsey fire. It's told me all these days that the air quality here in LA is good..as it's raining ash.
I am slowly getting use to the app. It is helping to understand outside conditions so I can better control my asthma.
I have never left a negative review in the App Store before. I feel if an app does not need my needs, I can delete it and not worry about it. However, this app is dangerous.
I live in an area that has been surrounded by wildfires for over a month. You’ve probably read about one of them – the Carr Fire – or heard about it in the national news. Because of the extensiveness of the fires to the south, north, east, and west of us, the air quality our community has generally been dangerous (an AQI of 150 or higher).
This app consistently has under reported the air-quality in our community, saying it is "good" with AQIs around 30. It has also significantly under reported the air quality in Redding, California, where the Carr Fire began and claimed three lives and destroyed almost 1200 buildings.
This malfunction is not on the same level as a malfunction of the game. People's lives depend upon the accuracy of air quality reports. And they are not getting it from this app. People in the high risk category jeopardize their health in bad air. And it’s not as simple as looking outside to see if it is smoky. Because of the nature of these fires, we have had days that appear relatively clear, but the air quality is very poor because of ozone as well as small particulates.
I emailed the developer of this app and explained the problem. I was hoping to get a response from him, but I’ve received none. So, for your safety, do not download this app. I’m going to contact Apple to see if it can be removed from the App Store.
Developer Response ,
Unfortunately I don't control the air quality stations or the values they report. My app reads (as transparently as possible) all of the information from the Environmental Protection Agency's air quality stations.
Not all of the air quality stations read particulate matter which is the primary air pollutant that a wildfire will create. Keep your eyes peeled for air quality stations that have a warning (the exclamation mark) and the warning message "Station is missing particulate (small) data. Air quality could be worse than reported." A similar warning will also show if the station does not report ozone values either.
It looks like (as of August 29, 2018) the station directly in Redding, CA is not measuring small particulate matter. The same is also true of the nearby Shasta Lake, CA air quality station. However, the Anderson, CA air quality station is reporting small particulate matter and ozone (it's currently reporting moderate air quality). Again, I am only reporting the values that the EPA air quality stations measure. If a station is not reporting a pollutant or it is incorrectly reporting values that is out of my control.
Depending on the station various air quality sensors can come online or offline over time as they require continuous maintenance and upkeep (all performed by the EPA).
This will be true of other air quality apps as they also get their data from the EPA.
I'm sorry that I did not get your email. Please email email@example.com or go to Air Lookout -> Settings -> Email to reach me and I'll be sure to respond.
