Description

- shows publicly available air quality data for your locality (chosen automatically based on IP address, or manually by you)
- gives 1 hour weather forecast (including air quality data & pollen prediction, where available globally)
- lists potential pollution source data, such as electrical generation, aircraft overhead & road traffic (availability of data varies globally)
- menu bar icon changes colour to match current AQI PM₂.₅ conditions (and can show AQI numerically too)
- each data source is clickable to launch further information to see trends & forecasts
- notifies if the AQI quality worsens beyond a threshold you set, or separately if it improves below a threshold you set (ideal to help decide if you want to go for a run or not!)
- updates its metrics every 20 minutes
- simple graphics help make sense of the numbers given
- free open source software

Data is sourced from PurpleAir (only publicly available sensors for now), WAQI/AQICN.org, SmartCitizen, CO2Signal, OpenSky, Telraam & ClimaCell.

I am actively developing this app, and am happy to receive comments, feedback & suggestions!

What’s New

Version 1.22

- added running averages for PurpleAir users (either numeric or chart, depending on whether AQI numeric is shown in Menu Icon) - fair dues to Drew again for the suggestion!

Great app, responsive developer!

With air quality in the bay area currently touch and go it's great to be able to get a quick sense of whether it's safe to go outside or open the windows, and Miasma provides just that ability. I am able to pin the menubar widget to my PurpleAir sensor and know in a glance what's going on or a quick check of the popdown menu and I immediately get other weather vitals from the same sensor. This is basically exactly what I wanted and I'm 100% satisfied.

I'll add that I started to have a crash-at-startup bug with a recent update and reached out to the developer. Within minutes I had a response and after a quick exchange they'd isolated the problem and provided a new build that addressed the issue (even though it's well into the evening in their time zone)! Outstanding service and responsiveness in addition to a useful app. Thank you.

Great App, one suggestion

I'm installing this on my Mac to have an ambient monitor of my PurpleAir sensor, and it seems great for that. PurpleAir has several different correction formulas that can be used, and I'd like the option to use the EPA's Woodsmoke correction. This is fairly often different from the basic AQI value and more relevant during California Wildfire season. Thanks!

Developer Response ,

Many thanks for your review & suggestion (and hope you're keeping safe with wildfires).
I'm reading up on the conversion formulae - I'll give incorporating it a go ( from https://cfpub.epa.gov/si/si_public_file_download.cfm?p_download_id=540979&Lab=CEMM)

Ohyaaaaaaaaaaa ,

Works as expected

Love the Purple integration. Works just as I expected. The only thing I wish was different was being able to remove the "M" in the menubar. It doesn't make sense and would look a lot cleaner without it.
