*Escape pollution and dodge the smog!*
The Flow companion app from Plume Labs collects and analyses the data taken from your Flow’s PM2.5, PM10, NO2 and VOC sensors and gives you beautiful, easy-to-read reports, maps, and graphs.
*Ever feel trapped by air pollution?*
Air quality, AQI index, smog levels: with Flow, you can find the best clean air commute, hunt down fresh air playgrounds, eliminate chemical hotspots in your home, and that’s just the beginning.
*Did you know?*
Wind and weather, humidity and heat, atmospheric pressure, and many other factors create clean air pockets in urban environments. In fact, air pollution levels change up to 8X from street to street in the city, and even more from room to room indoors! Flow gives you the information you need to stay healthy at home or on the go.
*Stop guessing and start sensing!*
A new study from top researchers at King’s College in London shows that, with good data, you can reduce your exposure to air pollution by as much as 50% by making small changes to your routine.
***Key Features***
Track your personal pollution exposure with live data and daily reports: Flow measures real-time concentrations of PM2.5, PM10, NO2 and VOCs, as well as the AQI air quality level to give you everything you need to understand your exposure and build healthy routines.
Avoid the most polluted places: Flow tracks air pollution variations around you in real time, so you can find clean air.
Flow fits seamlessly into your daily life: Whether you're cycling, running, out in the park with the kids, or relaxing at home.

Version 1.5.4
Escape pollution hotspots! Starting today, you can get live alerts when your Flow detects dangerous pollution levels.
Ratings and Reviews
Nice idea
Nice idea but unfortunately these devices are not very accurate in my experience. I have two and they both have quite different readings at any point in time. I think the PM sensor is perhaps too small to be reliable and my research suggests NO2 is not really possible to monitor effectively with a small sensor (it only gives relative measures, ie going up or down). For anyone wanting better quality PM data I can recommend a Raspberry Pi with the enviro+ hat and PMS5003 sensor, though its NO2 sensor still has the same limitations as the Flow.
A promising start!
I love the Flow and the App feels pretty good, but the data views are currently a bit limited.
I really like the spot and move concepts and I really like that the relationship between the map and the graph which shows overall AQI over time, although it would be nice to see the actual time of each reading.
As well as the AQI (with its useful breakdown of each type of pollution) it would be nice to be able to view a graph for each of the PM2.5, PM10, NO2 and VOC separately.
Although I currently only have 24 hours if data it would be great to easily see data trends over months and even years based on various locations at certain times of day or times of year, possibly incorporating temperature or weather conditions like wind speed into this (data from the Met Office perhaps?).
I think it will be fascinating to see all of this change as the ULEZ is phased into central london
Overall I think this looks very promising and I am excited to see how this app develops.
Not sure it’s accurate
There’s a lot I like about the Flow. It’s well made and seems great, but fundamentally I am not sure if it’s accurate. If I test in my apartment it goes from green to red with NO2 at super high levels within minutes, but there is no NO2 source in my flat that could cause such fluctuations. My Dyson purifier that also detects pollutants doesn’t show such readings. I am just not sure which is right. Will keep trying it and will update my review if I can figure it out, but accuracy is my only concern, which of course is a fundamental one for a product like this.
