Hormones & Cities
Share how you feel, anonymously from your phone. Get back health insights for your neighborhood — powered by what everyone around you shares too. The more people contribute, the smarter the picture gets.
Your city affects your health, but who measures it?
We track GDP and traffic, but nothing tells you if your neighborhood is actually healthy to live in. Air, noise, green space, stress — these shape how you feel every day, yet nobody connects the dots for the people who live there.
You share a little about how you feel. Everyone's data comes back as health insights for your neighborhood — the more people contribute, the clearer the picture gets.
From a London street to predicted brain activity
A small proof-of-concept from our Hormones & Cities work, Mapillary street imagery around Borough Market, run through Meta's open TRIBE v2 vision-only brain encoder, mapped onto the fsaverage5 cortical surface. Tap a marker, watch where a sidewalk lights up the visual cortex.

How it works
Your data stays on your phone. Anonymous summaries combine with street imagery and a brain-encoder pass, then land in open table formats so humans, planners, and AI agents can read the city the same way.
50+ living indices
From water quality to happiness — real insights about your surroundings, built from what people around you share.
Open because cities should be
All code on GitHub. A community in Dhaka gets the same insights as Dubai — no paywalls, no gatekeepers. The more open the data, the healthier cities can become.
While we build this
The data foundation is already live. Explore terrain, population, buildings, and weather on our interactive globe — the same datasets that will power Hormones & Cities.
