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.

Outstanding Air Quality App


This is one of those Apps you See but don't see! I can't begin to tell you how outstanding this app is I truly thank the people who put this together and like the main gentleman who did this thanked his girlfriend for hanging in there for the amount of time it took him to have what I feel is an awesome Air Quality App I thank her also! Trust me down load this now you'll get the picture fast!

Good App, One Suggestion


App provides good air quality information in a simple, clean layout. One suggestion - on the Apple Watch complication, please give the user the ability to choose which air quality statistic to display. I live in an area where pollen is high, so I always see the pollen number rather than AQI on the complication. Would like to have the option to see AQI at all times.
