Sadly, this app has become essential if you live in Beijing. Use it every day.

Very good for a quick look at the AQI in the major problem cities. I agree that a great feature would be an alert and/or notification when the AQI is greater than a user-determined threshold.

Been using both before and after China trips and am glad to have this info.
