Sadly, it looks like that although the app is available outside of the USA, the data isn't. So pretty much a waste of time unless you live in North America. Pity it isn't mentioned in the description.
Perfect accurate and informative
I like it. It would be nice if there were an option for a more compact viewing of the data - even just smaller numbers, or a sortable list, something like that.
I love it makes it easier than having to visit aqmd or airnow. Love it recommend to people that have allergies or health conditions.
