What is Paku?

Paku is an air quality app built to help you monitor real-time air quality anywhere the PurpleAir network covers. PurpleAir is a company that sells affordable air quality sensors that anyone can set up, and has a huge network of crowd-sourced air quality data - but they don’t have their own app.

As a native app, Paku is much faster than accessing PurpleAir on the web. It also offers features that the web app cannot, such as widgets and push notifications.
