Real-time air quality monitoring for cyclists. Know what you're breathing, find cleaner routes, and join a community making urban air visible.
Stationary air quality sensors measure in limited locations to provide city-wide estimates, meaning pollution is not actually measured on most streets. To understand what cyclists breathe, we collect data where they ride.
See what you're breathing in real time. Our bike-light sensor measures particulate matter on every ride; the app tracks exposure and will suggest lower-pollution routes.
