Understanding AQI Monitoring on Apple Watch

Monitoring the Air Quality Index (AQI) on your Apple Watch empowers you to make informed decisions about outdoor activities, ensuring your health and well-being.

What Is AQI?

The Air Quality Index (AQI) is a numerical scale ranging from 0 to 500 that measures the concentration of pollutants in the air, such as ozone, particulate matter (PM2.5 and PM10), carbon monoxide, sulfur dioxide, and nitrogen dioxide. A lower AQI indicates better air quality, while a higher AQI signifies poorer air quality. For instance, an AQI between 0 and 50 is considered "Good," with minimal or no risk from air pollution.

How to Monitor AQI on Apple Watch

Apple Watch offers built-in features to help you stay informed about air quality:

  1. Using the Weather App:
  • Open the Weather app on your Apple Watch.
  • Tap the display to cycle through various metrics, including air quality.
  • If air quality data isn't available, ensure that Location Services are enabled on both your Apple Watch and paired iPhone. (support.apple.com)
  1. Adding an AQI Complication:
  • Press and hold the watch face to enter customization mode.
  • Swipe to select a watch face that supports complications.
  • Tap "Customize," then navigate to the complication selection screen.
  • Choose a location for the AQI complication and select it from the list.
  • Press the Digital Crown to save your changes. (thetechedvocate.org)
