Paku is the best app for checking PurpleAir. View sensors on a map, filter by indoor or outdoor sensors, and choose from AQAndU or US EPA conversions.
Paku also shows the average AQI over the last few minutes, hours, day and week, and lets you see these data points on the map as well.
Keep an eye on the AQI right in your Today View, with widgets that support showing AQI near you or a specific Purple Air sensor.
- Allows you to specify a separate conversion for inside and outside sensors. Inside sensors will default to no conversion.
- Removes the restriction from viewing averaging periods with the EPA conversion. While the averages aren't fully accurate, this matches PurpleAir.
- Fixed an issue parsing HTML characters in sensor names (thanks you Eric for reporting!)
- Improved the appearance of inside sensors in dark mode.
Ratings and Reviews
This is a great app for viewing air quality and I like being able to easily see my home purple air sensor readings on the widget! I do wish the messages varied between indoor and outdoor sensors because the messages can be misleading (for example, a couple of days ago the my indoor sensor was reading a pm2.5 of ~ 15 while all the nearby sensors outside were showing pm 2.5 of over 300 due to wildfire smoke, and the message for my sensor said “it’s a great day to be outside!”). However, this is a pretty minor complaint since you can easily see all the sensors on the map, and overall the app works really well.
Finally an app to view PurpleAir data!
I love how Paku lets me avoid the clunky PurpleAir website. The app is wonderfully simple and looks good.
However, the app is a little too simple. For example, the app never refreshes data. If I leave the app open and want to see the current air quality, I have to quit and relaunch the app. Ideally the app would refresh data automatically every 5-10 minutes. However, a manual refresh option is an absolute requirement for an app like this. Having to quit and relaunch the app just to refresh the data available is super obtuse and cumbersome.
Another issue is that PurpleAir sensors grab lots more data than only the AQI. I find PurpleAir sensors even more useful for their temperature readings than their AQI readings. The sensor saturation is so high in the San Francisco Bay Area that they make it really easy to see what all the microclimates are like around the bay. I can then use this to plan my outdoor activities. It would be fantastic if Paku allowed us to view temperature data from PurpleAir sensors.
All said, it's fantastic that Paku exists at all. I'd gladly pay $10 for this app as it exists today. Add auto-refresh and temperature data and I'd more than willingly pay $20. This app has huge value potential for my daily life. I hope to see it reach that potential one day.
Good start, hoping for more
Areas I’d like to see improvement:
- Ability to choose a sensor and stay with that sensor. I own a PA sensor and only want to see data from that sensor. I don’t want to see data from other sensors as I move locations.
- Get rid of the AQandU filter. I don’t like that filter nor trust the data it produces. If this app is going to force the use of a filter, it should be the EPA filter, not the AQandU filter.
- Provide time-based averages. Seeing the current AQI is only a small part of the picture. Gaining an understanding of how the AQI value is trending is immensely valuable and often times more valuable than the current reading.
Developer Response ,
Thank you so much for your feedback! I’ve been heads down on getting map support out, but you can also turn off the AQAndU conversion in 1.1.0. All the other asks are on the roadmap too. Enjoy!
Update: with 1.2.0 you can now choose a specific sensor for the widgets!
