I use this most days, especially prior to outdoor activities/exercise. I'm unsure of the actual science and hourly accuracy. If it's accurate through hourly monitoring and not just an estimate I would have to give 5 stars. Either way I do enjoy it's speed to be able to check, Although sometimes if the ozone or particulates are high, I don't ride my bike and get a little lazy. I know, do something else inside instead! Thanks ADEQ

This application is great for Phoenix and other Southern Arizona locations. I now live in Prescott and would like to know what is happening in northern Arizona. The fires have been particularly problematic. Thanks for creating such a great application.
