Paku for PurpleAir

Paku is the best app for checking air quality, on the go or at home!

Best-in-Class Air Quality Monitoring:
Paku uses PurpleAir to show you hyperlocal, real-time air quality, temperature and humidity. View any public sensor, indoor or out doors, on an interactive map, and enable AirNow stations for additional information.

Versatile Widgets:
Customize your Home Screen and Lock Screen with a wide range of widgets. Configure widgets to show the AQI from the nearest outdoor sensor, any specific sensor, or your own private sensor, or see real-time temperature or humidity.

Real-time Air Quality Alerts (Pro):
Configure alerts for specific sensors, and get real-time push notifications when the air quality index exceeds yours specified threshold. Whether you live somewhere with frequent wildfires or strong inversions, these notifications can be invaluable.

Private Sensors (Pro):
Add your private sensors to Paku, and view them on the map, in widgets, or configure alerts.

Cross Platform Access:
Paku is available on iPhone, Apple Watch, iPad, and Mac for seamless monitoring across devices.

Privacy First Design:
Your location never leaves the app, and Paku collects no personal information. Feel secure knowing we’ll never sell your data.
