Customer Reviews

Terrible after the redesign

After the redesign/rebrand to Air Matters from Air Quality, the Today widgets and Apple Watch complication are always out of sync, and it takes ages to load the latest data when opening the app. The glanceable information that had worked so perfectly before is now useless as every time I want to check the AQI I have to open the app, pull to refresh, and wait for the latest readings to load. Would pay to get the previous version of the app back.

Bad Update

I NEVER write reviews, but for this App I feel it's necessary. Last update is horrible. UI is MUCH worse than previous version, and the developer decided it was a good idea to charge 0.99/year to remove ads. Previously it was just a one time charge. I'm deleting this App from my phone, with the hope that there's something like the old China Air Quality App out there.

Apple watch app stop working

This app used to work great before the update. I used it on my Apple watch a lot but after recent update the app doesn't run on watch at all (attempts to start and just times out and closes) and the app's watch face complication doesn't return any data. I rely on this a lot being in China. Please fix.
