UK design studio Cellule has worked with medical researchers to produce Echoes, an app that lets users hear the sound and rhythm of their heartbeat.
Echoes was produced to test the possibilities of tracking heart conditions via smartphones.
But the app also aims to go beyond a purely medical function by letting users connect with their body and "contemplate your heart's unique rhythm".
For now, users can participate in the research project while enjoying colourful 3D visualisations of their heart sounds. They obtain the audio recordings by holdings the phone to their chests.
