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.
• Search and select any Purple Air sensor.
• Select and enable corrections such as the E.P.A.’s wood smoke correction and University of Utah’s AQandU correction.

Air Lookout Pro
• Morning and evening notifications will tell you current conditions and the forecast for your area.
• Favorite and track any station
• Detailed hourly graphs that show years of historical data for all E.P.A. monitoring sites.

Monitors PM2.5, PM10, Ozone, Nitrates, Sulfides, Carbon Monoxide and more (12 pollutants can be monitored from supporting air quality stations).

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.

Uses too much data

I was on a trip for a week and iOS said this app used 1GB of cellular data! Even in my home area it used almost 900MB for the previous month. Way too much data usage for an app like this.

Developer Response ,

I'm sorry that you are having this issue. Could you contact with more details that could help me look into this?

Some information that could be helpful to diagnose this problem: Are you using the Apple Watch app? App Watch complications? Widgets? Thank you.

Edit: Could you update to the new 2.1.2 version of Air Lookout and let me know if you still encounter this issue? Thanks.
