Murmur

Murmur lets you hold short range group voice calls over Bluetooth LE. Whether you're cycling, hiking or in a crowded place, keep in touch with those just out of earshot.

Murmur provides you with group voice call capability on your mobile device for groups of up to 16 at a time. The more people in your group the greater the range. Signals are relayed between devices in a mesh network.

Out on a group cycle ride or hike? Murmur allows you to talk to your group without relying on WiFi, data or a network connection.

No account needed, Murmur is completely decentralized, and never 'phones home'.

Low energy Bluetooth conserves battery life.

Murmur is cross platform compatible.
