Bubble, a map-first social app with rules about proximity

Field notes

Bubble replaces the usual social feed with a map of place-bound media. Its access model uses a default 2 km Bubble Zone and server-side authorization before media delivery, while activity areas require contributions from at least two people. The site also separates camera-captured Live moments from gallery-uploaded Memories across the map, viewer, notifications, and analytics. The public extract documents the rules and policy surface, but does not show whether the app can be used yet.
