FireChat

FireChat introduces a new way to chat: "off-the-grid". Now you can chat with people around you – even if there is no Internet connection or mobile phone coverage. Please note that FireChat is designed for public communications. It is not meant for private communications. Real names are not required. You may choose pseudonyms. Please exercise discernment when sharing information in chatrooms. Other people will be able to read your messages, your username and full name (just like with tweets). FireChat enables a new type of communication: 'firechats'. These live and anonymous public chatrooms can gather as many as 10,000 people simultaneously. You can create your own public 'firechats' for anyone to join about anything that interests you - whether it's the NY Yankees, Game of Thrones, League of Legends or Italian food. 

Whether you’re on the beach or in the subway, at a big game or a trade show, camping in the wild or at a concert, or even travelling abroad, simply fire up the app with a friend or two and find out who else is there.
