Air Lookout aims to simplify air quality.

Air Lookout currently supports the U.S. Environmental Protection Agency’s air quality stations in North America.

Unlike weather, air quality can be harder to understand. That’s why Air Lookout presents actionable information in easy to understand language.

Air Lookout works on macOS 11 and supports macOS Widgets so that everyone can access air quality information in a variety of ways and formats.

New for 2.0: Air Lookout Pro! While all the data to make daily decisions regarding air quality will always be free, Air Lookout Pro offers more features and more data for people who take air quality seriously. Once subscribed to Air Lookout Pro you will get: morning and evening summaries, saving favorites and the ability to browse historical data for all locations.

Home Site
• Select a home site to always show in your station list.
• Use a Home Site instead of sharing your location with Air Lookout.

• Quickly see how air quality has been changing throughout the week.
• Know if you can exercise outside, open windows or should take caution if you’re in a sensitive group.

Detailed Data
• View all reporting data from any E.P.A. air quality station.
• See every pollutant’s measured concentration and AQI.

• Browse all E.P.A. air quality stations by location.
• See every station’s reporting AQI.

macOS 11 Widgets
• Monitor any E.P.A. air quality station right from your home screen.
• Supports all sizes: small, medium and large.

Purple Air Widget for macOS 11!
• Find the nearest outdoor sensor.

Awesome and Clean Design

I love this app and check it often. I love the layout, it's both easy to use and very clean looking.

As someone with a breathing disability who’s job is mainly outdoors, I’ve been searching for an app to replace the American lung associations app that no longer works with IOS upgrades. My search is now over! This app not only shows the current air quality of my location, but nearby areas that I have to work in. THANK YOU! Simple to use. Easy to understand. Figured it out in less than five minutes. I use it every morning.
