It doesn't work and we live in Shanghai,every time I try to read Shanghai,it just blocks me completely.

The app has been blocked, hacked, or something. After several days of Hazardous air, suddenly a day & time with Good air has been displayed. The air I'm looking at is clearly not Good!

It hasn't updated since December 2nd, 2013 and currently says it's zero ppm, (it's actually 280). This app is now completely useless.

Of particle concentration that they recently added to the app. Well, I don't Really love to see those numbers, but it informs whether I wear a mask or not that day!
