Your city, but it plays.

Pin a song, an event, or a voice memory to a real spot on the map. Walk into it and it fades in. Walk out and it fades back to quiet. No app to open, no button to press — just the place, and what someone left there.

Three ways to leave something behind

Every circle is a small decision about what belongs somewhere.

Not a pin with a caption — an actual place that does something when you're standing in it.

Music

Drop a song on a bench, a corner, a whole block. It loops while you're inside the circle and fades — slowly, like a real room going quiet — the moment you leave.

Full fade · loop · resume

Event

Pin a happening, not a listing. Friends attend, flag themselves running late, and the host's notes — the buzzer code, the "BYOB" — arrive the moment they actually cross the line.

Attend · running late · arrival notes

Memory

Record your own voice, right there. It comes back with a little patina — old-tape warmth, a soft crackle underneath — like a found recording someone else might stumble on years from now.

Your voice · aged a little

No app to open

You don't tap play. The place plays itself — the second you cross into the circle, and only for as long as you're standing in it.

Leave, and it doesn't cut off. It fades, like a room going quiet behind you — not a stopped track, a moment ending.

Come back within the hour and it picks up where it would have been, had it kept playing the whole time you were gone.

Your live location is never stored — not by us, not for a minute. Other people only ever see a soft glow where something's playing, never where you've actually been.

Shared with the right people

Some circles are just yours. Some belong to a layer you share.

A layer is a private map for one friend group — invite-only, nothing public about it. Your circles, their circles, one shared soundtrack for the places you actually go together.

Personal Roommates Book club

Cities have a soundtrack too. Where it's launched, real composers pin real music to real neighborhoods — walk through and hear what someone actually wrote about that block.
Know who's around. An anonymous count of who's standing in a circle right now, never who they are — until you tap in.
Nothing lingers by accident. Give any circle a lifespan — an hour, a day, a week — or leave it there for good.

Plound

Drop the first circle when we launch.

Free to start — a personal layer, up to fifteen circles, and every song fades exactly the way it should.
