Badum vs Hear My Baby: which baby heartbeat app should you choose?
Last updated:
Both apps amplify the iPhone's microphone so you can listen to, record and share the sounds from your bump, and both say they are not a doppler or a medical device. The two biggest differences are platform and price: Badum is a subscription app on iPhone and Android, while Hear My Baby is a $6.99 one-time purchase on iPhone only. Badum also has a kick counter; Hear My Baby has AI chat support and a sex-reveal video feature instead.

Frequently asked questions
Can I use both Badum and Hear My Baby?
Yes. Both apps use the phone's built-in microphone and neither needs an accessory, so you can install both on an iPhone and compare what you hear. Only Badum is available on Android.
Does either app replace a fetal doppler?
No. Both apps amplify a microphone and neither is a medical device. A fetal doppler uses ultrasound and is a regulated medical device. Neither an app nor a home doppler replaces prenatal care.
Which app works earlier in pregnancy?
Neither promises a result. Badum says most parents first pick up sounds between week 20 and week 26. Hear My Baby's listing says to use it after 20 weeks, with best results at 27 to 30 weeks.
