Each gets a heart that they grip in their hand. The device measures pulse, which is supposed to represent how fast your heart is beating while talking on the phone to your sweetheart. The info from the hearts is sent via Bluetooth through the phone to the other person's phone and then to his or her own heart. When the heart heats up, vibrates, or its lights change colors, it's meant to communicate how a person's partner is feeling about them at that moment.
