App Description

Apple Watch owners can access localized air pollution data directly on their wrist, while details can also be checked on the big screen of the Apple TV.

Air Quality Index covers more data than any competing app including readings for ozone, CO, SO2, NO2 and of course PM10 / PM25.

▶▶ Air Quality Index has been featured on iTunes for 389 times all around the world!


Air Quality Index Top Features:

Air Quality Index is tracking air quality data of measuring stations from all around the world, and unlike competitors these data are detailed and include a forecast.
- When there’s a station online, we display its data.
- When any new data are published, they are updated on your device – no matter if it is an iPhone, iPad, Apple TV or Apple Watch.

Depending on the availability of nearby located measuring stations following air pollution data are displayed:
• PM2.5
• PM10
• O3 (ozone)
• NO2 (nitrogen dioxide)
• SO2 (sulfur dioxide)
• CO (carbon monoxide)

Weather data are available on the same screen as well and include temperature, pressure, wind, humidity and more.

• A forecast for all weather and pollution data is available, color coding for air pollution data reveals possible health risks immediately.

A simple list with statistics is one thing, Air Quality Index provides you with more than that! A map of the world allows you to pin point exactly where specific air quality data have been taken. This is especially helpful on the big screen of the Apple TV.

Of course, if you are interested in data from a specific location, you can type the name in the search box or browse through the list.

▶ No other app collects a comparable amount of air quality data from as many different locations throughout the world like Air Quality Index does!

Air pollution is a real threat. Being up to date is the first step to protect yourself!
Air Quality Index is the tool of choice for this purpose!


▸ Air Quality Index is collecting, sorting and displaying data from places from all over the world. It is possible that certain measurement stations are temporarily out of order or delayed with transmission of relevant data.
