View air quality index (AQI), as well as PM2.5 for most cities in China.
Unlike most other China air quality apps in the App Store, the AQI value in this app is calculated according to the most recent standards used in America, which is more strict from the standards currently used in China.
The app is completely adfree. All data is from aqicn.org.
Latest reviews of 极空气 - 中国空气质量指数 app for iPhone and iPad
Great idea
Really appreciate that this app uses the stricter US standards. At this moment the China index rates the air in Shenzhen as "Excellent" whereas the US index applied to the same data says "Moderate". It would be even better if the app allowed you to see the whole world, not just China, as it really helps add some perspective.

Shanghai expat!
Love this app. I find it accurate and reliable especially for where I am currently living. I check it very often as this AQI changes in a blink of an eye!

Was working great until
It stopped updating yesterday. I tried restarting the app/changing connections - nothing. Please fix.

Doesnt work
Often crashes right after startup, and when it doesnt, there is no data. It might work while actually located in china, but I want to check from the US so I can see what the pollution levels are for my coworkers in china, or before I travel there.

Simple and clear
Good app, could it adds "show AQI number on icon badge" some day?
