Google Maps can now tell you about air quality in your area, just in time for summer.
Air quality ratings range from zero to "400+," with lower numbers being better. To view ratings in the Google Maps app, tap the layers icon near the top right corner, then select Air Quality under Map details. The data comes from government agencies like the EPA, Google says, plus hyper-local air quality data provider PurpleAir.
This feature and one that adds a Maps layer showing live weather data were initially intended to launch "in the coming months"
