FAQ
Good to know before you listen
When can I hear the heartbeat?
Many parents first pick up sounds from around 20 weeks, once baby is bigger and closer to the belly wall. Every pregnancy is different: baby's position, where the placenta sits and background noise all matter. If you don't hear anything yet, try again in a quiet room a week or two later. What you hear can include blood flow and body sounds as well as heartbeat.
Is it safe?
Badum only listens through your phone's built-in microphone. It doesn't emit anything: no ultrasound, no sound waves, no signals of its own. It is simply your phone's microphone, amplified.
Is it a medical device?
No. Badum is a keepsake and bonding app, not a medical device. It does not measure, diagnose or monitor your baby's health, and it does not replace prenatal care. If you're worried about your baby's movements or anything else, contact your midwife or doctor.
iPhone or Android?
Both. Badum is on the App Store for iPhone and iPad, and on Google Play for Android phones and tablets.
Do I need a doppler?
No. You don't need a fetal doppler or any accessory. Badum works with just your phone. Headphones help you hear more detail while you listen live.
Badum is not a medical device and does not provide a medical diagnosis or replace prenatal care. Always talk to your doctor or midwife about your pregnancy and your baby's health.
