Earthly

Earthly is a touch-first collaborative mapping app for creating, discussing,
and sharing geographic datasets over Nostr.

Draw points, lines, and polygons; publish GeoJSON maps and map-backed Stories;
annotate maps with geographic comments; and work in MLS-encrypted Private groups.
AI chat can help edit multiple drafts using explicit editable and read-only
references. You choose what to publish.
Android Field sessions add explicit nearby-only collaboration over a shared
Wi-Fi network or hotspot, including chat, map editing, and one-time mirroring
of referenced map files for offline use.

Earthly includes its own local relay and Blossom service. Core nearby and
offline workflows do not require a separate companion relay app.
