About this app

There's nothing quite like hearing your child's heartbeat for the first time! Flutter turns your phone into a mini not-quite-stethoscope, allowing you to hear and record your child's heartbeat; usually starting at the 20-24th week of pregnancy (though some have found success earlier)

REVIEWS
"I am very pleased, enjoying the little heart beats! :)"
"Beautiful and intuitive."

NOTE: Some zodiac predictions are free; making and saving heartbeat recordings can be unlocked after a trial period to see if this is right for you. This app cannot improve without your feedback!

FEATURES
- Live monitoring and recording of your baby's heartbeat; works best during the last 12-16 weeks of pregnancy.
- Pulse estimation
- Live pseudo-PCG (phonocardiogram) readout of the heartbeat.
- Save, rename, and access your recordings for later.
- Share recordings and waveform videos
- Zodiac projections for your baby based on your due date. What kind of little person will they be? This offers infant and early childhood parenting thoughts based on their astrological sign.

TIPS FOR FINDING HEARTBEAT
- Take your phone out of its case and turn the volume up.
- Make direct contact with the skin
- Feel for the baby's back and place the phone's mic against that spot; it's closest to their heart. You can monitor your own pulse to help differentiate between yours and your baby's.
- A silent room, long recording, and positioning close to heartbeat yield the best results.
- Bigger headphones may yield better results if you're having trouble. The loudest frequencies of the heart are very low, and small speakers and headphones may not be able to play them as well.

NOTE: This is not a substitute for care from a medical professional. Contact a licensed physician for your prenatal care. If you have an emergency, call 911.

For bonding and keepsakes only — not a medical device. Do NOT use this as confirmation of the presence or absence of a heartbeat or to assess heart rate or strength. See an obstetrician for medical advice and care.
Hear, save, and share fetal heartbeat recordings; like a doppler ultrasound.
