Very inaccurate! According to the app, the measuring device is only a couple of streets from where I live, so walking distance away. Yet the temperature it shows is about 15 degrees higher than it really is. That's a huge difference and doesn't make me trust the allergens measurements, which was the reason I installed the app. Today it put the allergy reading in green and said that the quality was good, even though I've had lots of trouble breathing. Useless app, uninstalling.

Hi Helena, thanks for your feedback. The temperature information is not from the monitoring station but a weather information data source. If you doubt the accuracy of the pollutant data, please let us know the station name, we will check the data.

Pretty good app, really like that it does the air quality up in the status bar of my phone. It's often close to Purple Air, (the best data on air quality, not it's in app form.) Wish there were a sensor closer to our house, though, and I don't have the $$ to shell out for one myself. It could use some work changing between locations so you can check Quality where you're going, not just where you are, and it's really hard figuring out how to add locations. Also, the forecasts are inaccurate.

I'm glad I found this great app to track the smoke concentrations from our horrible wildfires. Seems very accurate so far. Helps me know when I should be wearing an N95 mask outside because the odor isn't reliable after you've been in it for awhile. One thing I would like though is to be able to eliminate extra foreign cities in the notification widget when you have that set to "on". Don't need Paris, Seoul or Bejing displayed at top.
