Hear My Baby uses your iPhone’s microphone to listen for abdominal sounds; it’s not a doppler and doesn’t emit ultrasound. It’s a lifestyle keepsake for bonding and sharing, not a medical device and not for diagnosis. Results vary with weeks and baby position (many families hear best from 16+ weeks, clearest around ~27 weeks). If you’re worried at any time in pregnancy, please contact your clinician. For peace of mind, you can use Airplane Mode.
How it works (quick start)
1. Find a very quiet room and remove your phone case
2. Place the iPhone microphone on your lower belly and move slowly
3. Our advanced audio engine isolates and amplifies fetal heartbeat sounds so you can listen and save the recording, and trim it to the appropriate moment for sharing quickly and easily.
4. Best from around 16+ weeks; clearest for many families at ~27 weeks. Results vary with baby’s position and placenta location.
Tips for best results
- Be still, breathe lightly, and try several positions around your bump
- Press the mic firmly against the skin; explore low and to the sides
- Bluetooth/over-ear headphones can make subtle sounds easier to hear
Important
Hear My Baby Heartbeat App is not a medical device and doesn’t replace prenatal care. If you’re concerned about anything in your pregnancy, please consult your clinician. Works on iPhone (not iPad). For extra peace of mind, you can switch to Airplane Mode while using the app.
Privacy
Your moments are yours. You decide what to keep or delete — and who gets to hear them.
A word from our team...
We never see your recordings, but LOVE to hear them so please tag us on Instagram.com/hearmybaby or TikTok.com/hearmybaby or Facebook.com/hearmybaby
16 weeks, Was able to find my own heartbeat but struggling to find baby, will try again in the morning
Developer Response
Hi Pie877, We don’t recommend using the app until at least 16 weeks and, for best results, until 27-30 weeks. So it sounds like everything is set up correctly and with a bit more patience you should hear your baby soon. Please don’t hesitate to contact us directly for more assistance via Facebook messenger or email support@impossible.amBest wishes, The HMB Team
Charged For App I No Longer Have
Kaecb
I was charged for this app but I didn’t subscribe to anything. I thought the app was free, it didn’t say in app purchases. I actually deleted the app so I’m not sure how they were able to charge my card.
Developer Response
Hi Kaecb, the app is not on subscription but there is an initial cost to download it. This is clear on the App Store and therefore Apple will have charged your account. We are not involved with payments and refunds so please contact Apple support for help with this. We would appreciate it if you would consider changing your one star rating as this is not an issue HMB could have helped. Please email us if you need any further assistance: support@impossible.amBest wishesThe HMB Team
Heartbeat on everything!
wasadogmomfirst
I tried using this app and I tested my arm like it said nothing but static sounds, so tested my belly like it said, static, I’m 18 weeks and am starting to hear it on my stethoscope but it’s not clear. So I tried it on my dog, static but a distinct heartbeat. Either the app works for animal not people or it’s a waste of money. Just be patient and don’t get suckered into buy buy baby.
Developer Response
Hi, we do not suggest you test it on your arm first! We show you how to hear your own heartbeat in order to know the device is set up correctly. As you found your dog’s heartbeat it sounds like everything was working correctly and you were just looking in the wrong place for yours. At 18 weeks it’s perfectly possible to hear your baby’s heartbeat but best results are found closer to 30 as the heartbeat is stronger. It can take some patience and technique to master. Best wishes The HMB Team
Scam
Snowballlz
This is a scam, even my husband has a baby sound lmaoooo
Developer Response
Hi Snowballlz, HMB is intended to be used with Bluetooth headphones which provides a very clear heartbeat once detected. Without headphones the app will pick up external noises more easily and likely cause feedback. If you are using the app without headphones please be aware of this and make sure your volume is set to around 30% Please email support@impossible.am for further assistance and we’ll happily help. Best wishes, The HMB Team
