Paku is the best app for PurpleAir, allowing you quickly check air quality and more:

→ Best-in-Class Air Quality Monitoring
Paku is fast and lightweight. View hyperlocal, real-time air quality, temperature and humidity from PurpleAir sensors, and enable AirNow stations for additional information.

→ Gorgeous and Versatile Widgets
Configure widgets to show you the nearest sensor, any public sensor, or your own private sensor. Widgets are available for your Home Screen, Lock Screen, Apple Watch, and Mac Desktop.

→ Real-time Air Quality Alerts
Configure alerts for sensors and get real-time push notifications when the AQI exceeds your specified threshold - and when it improves. Whether you live somewhere with frequent wildfires or strong inversions, these notifications can be invaluable.

→ Private Sensors
Add your private sensors to Paku, and view them on the map, in widgets, or use them with alerts.

→ iCloud Sync
Paku is available on iPhone, Apple Watch, iPad, and Mac for seamless monitoring wherever you are. Your favorites and settings sync to all your devices.

→ Privacy First Design
Your location never leaves the app, and Paku collects no personal information.
