Estimated revenue

A model estimate with a likely range, not a reported figure.

No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.

How this estimate is made

Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.

Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.

Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.

Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.

Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

About this app

Text from the App Store listing.

Listen for your baby’s heartbeat, record meaningful pregnancy sounds, and save the moments you want to remember—with your iPhone and connected headphones.

Belly Beat is a pregnancy listening and bonding app that uses your iPhone microphone and gentle audio enhancement to make subtle belly sounds easier to hear. No dedicated fetal Doppler or baby monitor hardware is required.

LISTEN FOR BABY

Connect your AirPods or headphones, place your iPhone gently against your bare belly, and explore slowly. Simple positioning tips and a live signal guide help you find clearer sound.

RECORD PREGNANCY SOUNDS

Capture audio clips directly in Belly Beat. Replay your favorite moments and build a private pregnancy sound journal organized by pregnancy week.

SAVE AND SHARE

Keep special recordings on your iPhone, then share them with your partner, family, or friends whenever you choose.

PERSONALIZED FOR YOUR PREGNANCY

Add your baby’s name, pregnancy week, and due date for a listening experience that grows with your journey.

PRIVATE BY DESIGN

No account is required. 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.

TIPS FOR BETTER LISTENING

  • Find a very quiet room
  • Connect AirPods or compatible headphones
  • Remove your iPhone case
  • Place the bottom microphone gently against bare skin
  • Move slowly and try several positions
  • Keep the headphone volume comfortable to avoid feedback
  • Be patient—results vary, and subtle sounds may be easier to hear later in pregnancy

A FETAL DOPPLER ALTERNATIVE FOR BONDING

Belly Beat is designed for expectant parents who want a simple pregnancy listening and recording experience without dedicated Doppler hardware. It uses your iPhone microphone rather than ultrasound.

IMPORTANT

Belly Beat uses your iPhone’s microphone to listen for belly sounds. It is a pregnancy bonding and keepsake app—not a medical device—and does not measure or monitor fetal heart rate.

Results vary with pregnancy stage, baby position, environment, and device. Belly Beat should not replace regular prenatal care. If you’re concerned about anything during pregnancy, please contact your healthcare provider.

What’s new

Release notes for the latest version, as written by the developer.

v14.0.0

Your first listen now comes with a little more guidance.

A short, voice-guided setup walks you through three listening spots, with clear cues for where to place your phone and how long to hold it. Complete it once, then go straight to Live Listen next time.

We've also polished the setup screens and audio prompts to make getting started feel smoother.
