The Best!

The best AQI app hands-down. And if you have a PurpleAir sensor it’s even better!
Incredibly responsive developer… I wish I could pay double for it! 👍🏻👍🏻

Best air quality app

Best air quality app for iPhone, iPad, and Apple Watch. I love the UI, the reliability, the watch complications, and the alerts which tell me when the AQI is getting bad or has improved. Highly recommended!
