Rumble is a completely off-the-grid application and delay-tolerant micro-blogging application that allows a device to connect, chat and share content (text and images) with other people around you. It doesn't require Internet to work and rely instead on Smartphone, Local Area Network (Bluetooth and Wifi) and human mobility to spread information.
