Update July 2026: Update 2I have upgraded to newest version. No change in ozone or PMs. Thank you for your art. Still my favoriateUpdate 1I didn’t receive a notice that you replied. Meantime, I rely upon this air quality app and boosted to 5 stars. Most reliable and informative about ozone and PMs. I came back to the App Store to read about the source and now see an upgrade is available as well (haven’t done so yet, a little chicken).I am correcting my rating even though so much time has passed.2021 RatingWhat happened? I liked it 4 stars worth but now 1 star. Past few days there have been no readings. “Not available”, although available on other apps.
I really wish Apple would give me notifications of reviews so I apologize for the delay in response. There were access issues with the data provider that took a few round-trips to resolve and there have been other changes as well. If you're still seeing issues, please email info@aqeye.com so I can see what's up. If you're no longer seeing issues, I hope you'll revisit your rating. Thank you!
