FAQ
How does Belly Beat work?
Belly Beat uses your iPhone's microphone and gentle audio enhancement to help you listen for subtle belly sounds. You connect headphones, place your iPhone gently against your bare belly, and explore slowly. Simple positioning tips and a live signal guide are provided.
Does Belly Beat require any special hardware?
No, Belly Beat is designed to work with your iPhone and connected headphones. It does not require a dedicated fetal Doppler or baby monitor hardware.
Can I record and save the sounds I hear?
Yes, you can capture audio clips directly within Belly Beat. These recordings can be replayed, organized by pregnancy week, and saved privately on your iPhone.
Is Belly Beat a medical device?
No, Belly Beat is a pregnancy bonding and keepsake app. It uses your iPhone's microphone to listen for belly sounds and is not a medical device. It does not measure or monitor fetal heart rate and should not replace regular prenatal care.
What are the subscription details for Belly Beat?
Some features in Belly Beat require an auto-renewing subscription. Payment is charged to your Apple Account upon confirmation, and subscriptions renew automatically unless canceled at least 24 hours before the current period ends. You can manage or cancel subscriptions in your App Store account settings.
How private is my data with Belly Beat?
Belly Beat is private by design. No account is required, and live microphone audio is processed on your device. Saved recordings remain on your iPhone unless you choose to share them or explicitly enable diagnostic audio sharing, which is off by default.
What are the best tips for listening with Belly Beat?
For best results, find a very quiet room, connect AirPods or compatible headphones, remove your iPhone case, and place the bottom microphone gently against bare skin. Move slowly, try several positions, and keep headphone volume comfortable. Patience is key, as results vary and subtle sounds may be easier to hear later in pregnancy.
What devices does Belly Beat support?
Belly Beat currently supports iPhones. It was released on 2026-07-10 and its latest version is 1.0.3, last updated on 2026-08-06.
