Ratings and Reviews

Not configurable enough


I do not want the phone to detect my current location. I only want to choose which locations' air quality is displayed. But the first location listed seems to be automatically generated. It is NOT exactly my current location, and also the air quality info for that location is wrong. Please allow users to delete any location, including current location.

It's insists I'm 200 miles away


For some reason when I look at the default "near me" reading, it's showing a city 200 miles away. When I try to add my actual closest city, it cascade through its (very poorly designed) city checker and again insists that I choose the same city 200 miles away. I want local results, not ones on the other side of the state!

Cannot Delete Locations

New Haven Driver

I like seeing the AQI of cities in the U.S. However, why is there no way to delete locations? I added several of the Beijing districts and now I want to delete them. So, this app will be deleted until that is figured out.
