*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.
***Flow in the press***
“I hope many people living in polluted cities will end up using Flow.” —Techcrunch

Freezes iOS 11.3 devices.

Super slow to download data from device. On iPhone 5Se after you started it freezes the device which requires a hard reset. The device has a design problem in the docking station where the power connector is not connected and the device in the socket drain easily the battery. The app display stupid information for a just in house use. No major update in the data display, no option to have one single graph of the parameters with a longer history than the last 24 hours. I would say not recommended.

Hello Sensor - Goodbye Battery

Faulty readings. GPS will only work if you select locations services “Always” so your battery is dead after a short day working. I spray hand sanitizer after touching crosswalk buttons - and that throws the sensors off for 45 minutes. And waking up on the morning... forget about checking the air through the night - you have to export and email the data to yourself just to see what the air quality was at 11pm while you were asleep. I appreciate what they want to do - but they are trying to jump to the finish line instead of growing this product organically, working with users to slowly develop something good and stable. I am sorry I ever found this app and wasted money on the sensor (which has never lit up since the day I started using it). What is the home button? It does absolutely nothing. A start up that will flop if this keeps up and you are left then with useless plastic junk.

The constant use of GPS & BT is not good.

I’ve been using the Flow for a couple days now and with it using my gps, Bluetooth and running in the background on my phone I’ve lost 35% of my battery life on my iPhone X using this app. They really should have put a gps in the device itself and a low power Bluetooth connection to maintain connection until you need to preform a full sync. I love he idea of knowing what the air quality is around me but not at the cost of charging my phone way more frequently. I would also like to add that the app needs a day,week,month and year view for your data. Hard to make choices about the air your in if you can’t view a historical visual layout of how things get worse or better though out the year. Maybe my walk to my coffee shop is better on the weekends than the weekdays... I will be returning this air quality monitor due to these issues.
