The verdict

Paku shows the air quality outside your door on a live map built from PurpleAir and AirGradient sensors and official AirNow stations. Smart Select picks a reliable sensor near you, and widgets put the number on your Home Screen, Lock Screen, Watch and Mac. Alerts when the air turns bad, Live Activities and private sensors need Pro, which has a lifetime option.
