Was not working for over a month (from late march to late april?) but glad that it is back. Thisis the best pollution monitoring app i have found so far. Love the 24hr and 30day graphs and ability to customise the readings
最近有个奇怪的现象，启动 AQI 后再返回，过段时间就会自动播放音乐，从最近程序中划掉 AQI 后，音乐就没了。 请问是什么状况？怎么解决？
It's working again! Great app for aqi in China!
Interesting, you can see the correlation between app and smog in Beijing
