The various indicators for pollution do not work in Taiwan. For example.. during the 1st and 15th of every month, tens of millions of people will burn copious amounts of religious paper for hours on end, but not ONLY on those days. The current fires indicators do not reflect this AT ALL. This isn't the only issue I've found in Taiwan with this app though. During the religious festivals the fire and smoke are not reflected whatsoever in the air quality index, and what is shown is greatly inaccurate all over Taiwan.
