Never receive any push notifications

And the developer didn’t answer mail questions, then what’s the point of this paid version other than the free one.

Ok but could be better

I don't find the faces indicating the current AQI level to be very helpful. Please just put the AQI number for the nearest station on the watch complication, and don't crash that app, and keep it up to date hourly.

Watch and widget rarely update

Paid for this to get a watch complication and today widget. They rarely show a readout, and when they do it doesn’t match the readout from this app or other apps (doesn’t seem to be a units issue or station selection issue).
