An easier way to check local air quality sensors

Paku is much easier to read and use than the Purple Air website. You can localize it wherever you are. You can create favorites and save them. With the purple Air website, every time you use it, you have to change the setting for a conversion to US AQI. With Paku. As a default is US AQI. You can also view the temperature reading from any sensor on the same screen as the AQI. All this is with the free version.

Health App

Live data is a major resource to knowing when to put on an N95 mask to stay healthy. Wish there were sensors and live displays showing air quality in every park so this information was available to everyone. Until that happens this app is the next best thing!
