PurpleAir Companion

★★★★★ Discovered Purple Air and then this app. Works great for me. I find the sensor info refreshes quickly, and I'm not looking at 2 hour old data like the last app I was using. Easy to quickly reference a series of saved sensors showing current and past values and a tap on map icon takes me to the website where I can get an expanded view.

★★★★★ I'm still getting to know this app, but so far, it seems easy-to-use. I like being able to check air quality in a variety of communities where I might go to visit family, or plan a trip for the day. The "Real Time" reports seem to update fairly quickly, plus I can force a refresh. I can also chart trends by viewing past data. One nice touch is that the explanation of AQI Levels has color-coded highlights that correspond to the demarcations of healthy to unhealthy air.

★★☆☆☆ Super buggy and froze constantly. Can't even complete setup and pick sensors. Galaxy Note 10. Uninstalled, worthless. Just use website.

★★☆☆☆ No sensors are shown but plenty are present on the purple air website

★★☆☆☆ Not sure why this app exists and is so hard to set up. It requires that you request a pair of api keys to use, but then does so over email. Almost 24 hours after install and request I still haven't received more than an automated response and haven't been able to use the app. Instead, I made a shortcut to the purple air website map on my home screen. Done. This app is more trouble than it's worth.
