Libbi

Record your heartbeat and voice while you're pregnant. Play them back to your baby after birth — the same sounds they heard in the womb. Libbi is a sound diary for the most precious time in your family. Hold your phone to your chest and record your heartbeat, sing a lullaby, or capture the doppler at an appointment. Trim, label, save it under your baby's name. Then play it back. Layer it with rain or the womb sound. Let your baby fall asleep to the same heartbeat that lulled them in utero — yours.
