Shell is not a medical device and therefore it does not display the BPM. Shell helps you connect with and enhances bonding between you and your baby. It also enables you to share the experience with family and friends. Please note that Shell is not intended to replace the advice of your physician and your regular check-ups.
We recommend listening to your baby's heartbeat from week 25 of your pregnancy. In some instances, if the baby is still and in a convenient position, it is possible to hear the heartbeat even from the 18th week.
