Flow 2


  • Make commuting a breeze.

    We are keenly aware of which transportation options emit more CO2 but it’s harder to know which one is best for your lungs. Car, bus, train, subway, hyperloop or rocketship: Flow helps you compare the data between your commutes and pick what’s safest.

  • Take it for a spin.

    Flow is a cyclist’s best friend. It will help you choose the smartest itinerary to drastically reduce your exposure to pollution. Pedaling in the smog is a thing of the past, you shouldn’t have to fear peak hour!

  • Give your lungs a chance.

    Flow will also be a valuable partner for the sensitive urbanite. While it won’t replace your asthma or allergy treatment, by warning you of pollution peaks and giving you timely guidance it will help lift a weigh off your shoulder.
