Do you think it's impossible to chat offline and without mobile coverage? FireChat is a surprising messaging client that uses Open Garden technology to allow you to communicate under these circumstances.
Chat with your contacts or with any user of the FireChat network.
FireChat uses a wireless mesh network that is created between all the users that have the app installed. Thus, even if you don't have access to the Internet or mobile coverage, you'll be able to continue chatting with your contacts.
Obviously, this application works better in crowded places, such as concerts, shopping centers, sports events...
Not only a chat system
Want to know what's going on around you? With the "Nearby" function you can take part in group chats with users that are in your area. With the "Everyone" mode you can see what people are talking about everywhere.
