Location-based social network

The map is the feed.

Atlas connects you to friends through where you are — not what you post. See who's nearby, drop notes that surface when friends arrive, and share your route live.

How it works

Atlas layers presence, notes, and routes onto a single live map — so everything your friends do shows up where it happened.

What Atlas does

Built around where you are

Live presence

◉

See your friends, right now

A real-time map shows who's online, where they are, and how far away — updated as people move. No check-ins. No stale data.

How it works

WebSocket presence sync keeps markers fresh under 30 seconds. Each pin shows distance, heading, and last-active time, continuously.

Proximity notes

◈

Notes that wake up when you arrive

Leave a note at any location. It surfaces automatically when a friend walks in — a message that knows where to deliver itself.

How it works

Notes trigger silently on geofence entry — text, photos, and tags included. No push-notification spam, just context when it matters.

Live routes

◎

Share your path as you move

Start a route and let friends follow your trace in real time. Great for meetups, commutes, or letting people know you're almost there.

How it works

Routes stream via WebSocket and render as animated beam traces on the map. Friends see your position update live along the path.

Place messages

◫

Conversations anchored to spots

Start a conversation tied to a specific place. Messages live at coordinates — context travels with location, not just a thread.

How it works

Direct messages and group threads can be pinned to a place. Past conversations resurface automatically when you return to the same spot.

Friend clusters

⬡

Know when your circle converges

Atlas detects when multiple friends are in the same area and surfaces a cluster card — so spontaneous meetups actually happen.

How it works

Cluster detection runs server-side with a configurable radius. You get one ambient notification per cluster, not one per person.

Spatial memory

◱

Your history, organized by place

Every note, route, and message is indexed to where it happened. Browse your past by map — not a reverse-chron timeline.

How it works

Past activity clusters by location heatmap. Tap any zone to replay notes, routes, and messages from that time and place.
