Whenever I tap a match on the home screen the app hangs infinitely on an empty page with a loading gif. There's no way to dismiss this screen. The app has to be force unloaded and reopened. Then the user has to endure the long splash screen again. I don't know if any features work because I don't have time to force-unload the app and wait for through the splash screen in order to try them all.

Would be 5 stars if it had worldwide coverage. If you only care about locations in the US this is the best app I’ve tried. All air quality apps only update once per hour. This one tends to update about 15 minutes after the hour, but afaik based on this app and others, updates are sensor dependent.
