Animo is an application on smartwatches that allows friends or couples to share their heartbeat with each other. Animo stands probably for animated + animal (a pet). This tiny creatures have their own shape as their identity and jump on the owners' smartwatch in a rhythm of the owners' heart rate. One user can tap the smartwatch and send her/his Animo to the partner's side (on her/his smartwatch). The two Animos will meet each other and jump together.
