This is Radar Chat.

Leave Digital Messages in the Physical World.

Hyper-Local Communication

Leave a post somewhere in the world and others can only find it if they visit the same location.

Organized into Maps

Posts are organized into maps. Subscribe to maps that interest you, like foodtrucks, coffee, or garage-sales.

Configurable Loudness

Choose how “loud” your posts are, whether it be a long-lived whisper or a short-lived shout.
