User Reviews

From what I understand this is one of the most accurate AQI. There is zero guessing and no predictive modeling involved as it uses high-grade sensors. My only reason for giving 4 starts instead of 5 is I want widgets, for a quick easy glance at the AQI of my current location.

Partial load. Has to be closed and reopened. Plumes don’t show until midday which is annoying. Great resource for monitoring situations.. when it’s available.
