Offing

No bars. No problem.

The social network for places where the internet isn't. A local feed, chat and presence radar for festivals, protests, stadiums and disaster zones, carried entirely by the phones in the crowd over a Bluetooth mesh. No servers, no accounts, no signal required.

How a post travels

  1. 1

    Post

    Write a post, a chat or a wave. It's signed on your phone with your own key before it goes anywhere.

  2. 2

    Hop

    Nearby phones pass it along over Bluetooth, hop by hop, and each one checks the signature before it relays.

  3. 3

    Fade

    Everything expires. Posts live six hours in the mesh, and the feed forgets them with it.
