A recent 2024 report from the “State of the Air ” depicts that roughly 39% of the U.S. population lives in cities (and states) with degrading air quality despite ongoing efforts to clean up air pollution.

This, in turn, has contributed to a rise in respiratory diseases and other health complications. So, it isn’t surprising that residents are now curious about the air quality in their areas in real time. What if we told you your iPhone can be a tool for that?

Both iPhones and Apple Watches are programmed to enable users to monitor the air quality index in the local area. If you are wondering how, this detailed guide will walk you through all the details.

AQI, or Air Quality Index, is the “scale” that provides a clear understanding of the quality of the air in the regional and local areas.

In the United States, the AQI is often referenced under EPA with a scale ranging from 0 to 500. It comprises five different pollutants, including:

  • Ground-level ozone
  • Particle pollution
  • Carbon monoxide
  • Sulfur dioxide
  • Nitrogen dioxide

All of these individual elements are combined to provide a comprehensive AQI reading for your area.

Here’s a breakdown of the AQI and the level of health concern it imposes in the U.S:

Orange101 to 150Unhealthy for sensitive groups, meaning people that have chronic ailments.
Red151 to 200Unhealthy
Purple201 to 300Very unhealthy
Maroon301 to 500Hazardous

Note: AQI readings are country-specific, meaning that the indexing or scale the U.S follows might differ from what’s observed in the U.K., India, Germany, etc.

With the consistent growth and evolution of technology, we now have readings of the AQI directly on our iPhones, meaning that you won’t have to go out of your way to watch the news or such to keep up.

Following are a few different ways you can check the AQI on your iPhone:

1. Using the Weather Application

If you use an iPhone religiously, you already have a weather application installed. So, follow these steps to check the AQI:

  • Unlock your iPhone and then open the Weather app.
  • Scroll down and select the region you are in.

Doing so will reveal the air quality index in your area, allowing you to gauge whether you are breathing in healthy air.

If you aren’t satisfied with the readings from the standard Weather app on your iPhone, the popular Air Quality Reader app is available on the App Store. It provides more in-depth information regarding the air quality and other associated insights you might be interested in.

The best thing about installing this app is that it converts into a widget, which you can install on your home screen. So, anytime you are curious about the AQI in your area, you can unlock your iPhone, and the data will be available on the home screen.

The app also has a map and dedicated search option, allowing you to look up specific cities and areas with the AQI you wish to check. In addition to this app, several similar applications can be checked and installed from the App Store.

3. Check in Google Maps

Another popular application that provides details about the air quality in your area is Google Maps. You’d have to download and install the app on your iPhone.

Once done, open the app and go to the top right corner of the screen to tap on the map button. Under that, you will find “the Air Quality” option; click on that. You will find specific areas that you can look up to see the AQI in that area.
