Great idea but how reliable I have been using this app for a couple of weeks now and it does provide AQI as expected. However on closer inspection the number shown for a particular city is not really representative. Often the number shown in the widget does bit match that shown in the graph and without warning the graph numbers, change? I had thought it was bring smart and showing me the nearest measurement station but I don't think it is. Great work by those involved will increase star rating when scales are correct in app.

I live in Suzhou and the app tells me my nearest city is Nanjing. The city search function doesn't work either.

Looks well. But the graph and map are shown in a browser not in app.

Good app, bad data Great widget, but the data does not match the sources it's supposed to be drawing on, at least in Taiwan. The data in the app doesn't match the data on the Taiwan EPA website, please clarify.
