Murmur is a free, open-source, anonymous messaging Android app that does not require an Internet connection. Messages are not sent in real-time like with other messaging apps that rely on the Internet and have a central server, but instead spread directly from one device to another without user intervention

Murmur 2.0 (Revival) is a modern port of Murmur 1.0 (Rangzen)
