Air Quality Reader Hack 1.2 + Redeem Codes

I love having the widget and the new sensor popover is great, but I’m unclear about where the data is coming from and when it’s updated. For instance, when consulting the Purple Air web app map I often see very different readings for the same sensor. For instance, as I write this, the nearest sensor reads 76, updated at 8:33 (5 minutes ago) whereas the app reads 61 (updated 6 minutes ago according to app). Is the app pulling from a different API or is stale data? It might be helpful to have an actual date, time stamp as opposed to relative date. 6 minutes ago relative to when? That might help give some more confidence about readings in the app. The air quality in Colorado varies greatly with the wind throughout the day, so having current readings before a walk or run is very important. Overall, great effort and with some small tweaks this could be very useful.

Thanks Bret! Feature request: PM 0.3 seems to be more closely related to smoke levels than PM 2.5. PurpleAir has both options in the web page.

Thanks for this app! Love having PA data in an iOS widget. I own a PA indoors sensor and would love to have the option of seeing that data in addition to outside sensors.

If I were king for a day I’d love to see a widget option with just two data points and no map. Maybe field one a favorite sensor (ex. my indoors sensor) and then field two the closest outdoors sensor. The current implementation is still worlds better than having to navigate the PA site on an iPhone though, thanks!

It’s a simple, no strings attached, app that shows your location and nearby Purple Air sensors. Your choice of EPA AQI or Purple’s. It even has widgets for at a glance data. Really simple app and great implementation using Apple Maps and sensor data isn’t obscured by your location dot. Thank you for coding this!!! 💙

This is such a simple app that give you just enough air quality information. The widget is just a perfect size and provides all the AQI data you need before heading out the door. Works well on iOS 14 on an iPhone 6s!

This is an amazing app. It’s crazy that Purple Air didn’t make this first party. Thanks for this Bret.

Version 2.0 should let you sign in to your personal Purple Air monitor in a separate view. Right now it’s a just a cheap webpage. Should also include normal features like “remember me” etc.

Thanks Bret, this is the exact app that I needed to tie-in to my PurpleAir sensor and the PurpleAir map. No frills is fine - open the app or widget, and there are your location’s AQI readings in real time. Of course, your map interface allows pinching and zooming to other locations, as well.

Extremely easy/basic interface. You can’t tap on a location to see additional details, it’s just the AQI #s laid on a map.

I just have two wishes: 1) Pollen data for allergy sufferers 2) Notification options for when the quality drops below a specific level.

Love the app but not sure where the data comes from or how often it’s updated we my sensor shows up on the purple air map on the webpage but using this app it does not show up.

Thank you for creating this simple and effective app. It’s thoughtful, timely and helpful.

FYI to other reviewers:

It should be clear—data is drawn directly from hyper-local Purple Air sensors, based on location.

I’ve found these Purple Air readings to be far more consistently an accurate average of my local AQI than anything reported via Apple’s weather app—every single day.
