Do It

Help people keep connected during disasters and in remote places, even when cellular networks fail

How do you create a more connected network of people that can help one another during times of disaster? Get their phones to communicate with each other locally, without depending on cell towers. We're working with the New Zealand Red Cross to offer free, open source technology that can be downloaded on smart phones (Android only for now), to let them communicate locally without cell towers. This software uses the Wi-Fi in your phone to form a mesh network that lets you communicate privately with those nearby. We are also making low-cost "mesh extenders" that can extend the range to a few blocks each, and that can cooperate with one another to let you communicate over even greater distances. We need people to help test our experimental software by downloading it here:, and to help us finish the mesh extender design by spreading the word about our Indiegogo campaign.
