Listen to your baby's first heartbeat.

Shell by Bellabeat is a non-invasive Fetal Heartbeat Listener intended for expectant moms and families alike. It enables you to listen to the sound of your baby’s heart in an innovative and completely natural way without the use of Doppler technology. Like resting your ear against the tummy and turning the volume up.

Shell works by placing your phone’s microphone on the belly. An advanced algorithm, the first of its kind, non-invasively captures sounds from the womb and isolates the heartbeat.

Making this major life event interactive, Shell provides a unique way to announce a pregnancy with recording and sharing features and also offers a way to keep your inner circle connected with your growing bundle of joy as it progresses toward birth.

Depending on how far along you are, easy-to-use in-app tutorials depict where to position your phone to achieve optimal results. The tutorials are found in the side menu under ‘Education’.

The most recent addition to Shell is the kick-counter: an easy, non-invasive test that you can do at home to check your baby's well-being. The test helps you monitor your baby’s movement to alert you to any decreased activity, generally considered to be sign of potential problems.

Key features:
-Find and listen to your baby’s heartbeat
-Record and store an unlimited number of tracks
-Share the recordings with loved ones
-Enhance the bonding experience between you and your baby
-Kick counter test

Key components:
-Algorithms that filter out ambient noise to accurately enable listening
-Easy and safe to use. Just open the app and start listening for that tiny, rapid pulse.
-Non-invasive technology enables you to safely use your iPhone
-In-app tutorials for higher success rate


We like to ensure the safety of all moms and babies. Shell is safe to use but as a precaution, please place your phone in airplane mode.

For best results it is recommended to use Shell from week 30. In some instances the baby’s heartbeat can be heard even earlier.

Please note the Shell is NOT a medical device and is NOT intended to replace any medical advice given by a physician.

Shell is supported on the following iPhone devices: 5S, 6, 6 Plus, 6s, 6s Plus, SE, 7 and 7 Plus.
