Says what it does and does what it says. Really a very well built application for monitoring air quality worldwide. With the number of stations available for analysis to this application, I find it informative, intensely detailed, and trustworthy. I love this app! IQAir does a good thing and is worth supporting.

was very helpful, but lately (10/24/2026), any widgets I create for other locations other than my own stop working (says no data available). the length of time until they stop working is a few days. in the past (before latest update), that was never a problem even with having 7 widgets. also, those widgets for additional locations aren't updating properly (10/24/2026).

Widgets frequently freeze and stop updating. Requires fully deleting the widget and recreating it to get it to work again. Basically makes the widgets pointless since they aren't reliable. App works fine for controlling air purifier which is it's most important feature, so at least there's that.
