Real 5 Star Reviews
"I never leave reviews, let along pay for apps but let’s just say I tried this , and it def works" - Lov3r_Gurl IG (USA Sept 2025)
“I always find 'it' (sic) eventually and the rhythm is clear and strong. I love that I can record them to keep.” - T Lucker (Australia 2025)
"I downloaded this very skeptical... It took me about 45 minutes of laying down, very still, with noise canceling headphones on, but I HEARD IT. I am almost 18 weeks pregnant. From one momma to the next, it’s worth it." - Baby'sHeartbeat (2025)
“It took some time and patience... thank you for creating this cheap, awesome technology to use at home.” — Niki
“I was skeptical at first. Great app! Worth it.” — Legretta
How it works
- Hear My Baby uses your iPhone’s microphone to listen for abdominal sounds; it is 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.
- 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.
- 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

So when I first downloaded the app I was super skeptical because I had downloaded a few other similar apps that didn’t work at all and paying 5 dollars seemed like it wouldn’t be worth it. Despite my reservations I downloaded it anyway and was disappointed I couldn’t find her to save my life. I was about 22 weeks at the time so I figured I’d surely be able to find her heartbeat being halfway through my pregnancy. I almost undownloaded the app and asked for a refund but something told me to just wait and I’m glad I did. I’m 25 weeks now & was able to find her heartbeat almost immediately after hitting the listen button. I maybe could’ve found her earlier but I waited a little longer just to make sure her heartbeat was strong enough to really be picked up by the app versus at the drs office. I’m glad I kept the app and would highly recommend it to future moms. I’d just tell them to give yourself some time if you don’t hear the baby at first and not to get discouraged.
BEWARE!!! THIS APP IS MANIPULATING A BABY’S HEARTBEAT

We were so excited to be pregnant but i couldn't be seen my my Dr till after the holidays so I bought this app for “REASSURANCE”! I found what I thought was a babys heartbeat and was happy and posted it! Hell even the BPM was at 156 ( typical baby heart rate) When i finally went into the Dr she discovered i did have a gestational sac but a baby never formed so I never had a forming baby! This app manipulates a babys heartbeat! I actually posted a recording of what ive been hearing for weeks on the facebook group, check it out!!! Sounds just like a babys heartbeat except there’s absolutely no baby, another mom used it when she wasn't even pregnant and she found a babys heartbeat another mom as taken tests, all are negative results but she also has found a babys heartbeat, its sad how we moms are getting false a manipulating sounds !!!Please MOMS do not use this app for peace of mind or for reassurance! If you are having an issue don’t hesitate for one second to see your provider or the nearest ER! DO NOT TRUST THIS APP OR ANY APP when it comes to your pregnancy or your health! Trust medical testing, see your provider! Be excited for your pregnancy and excited about your visits to see your baby on ultrasound and a medical doppler! Best of luck to all you mommys and your sweet babies!!!

Hello SOFCC, thank you for your comment, and in the strongest possible terms we do not recommend downloading HMB for reassurance, and we make that clear in all our information, it is NOT a medical device. We also recommend trying the app only after 16 weeks and not before and best results around 27-30 weeks. To address the issue you raise - the recording you posted, which we've listened to, sounds like it is caused by the volume being too high and is a sound feedback loop (often appearing to have a high BPM - but we don't include a feature to measure this within the app). We recommend that the volume is placed at 20-30%. This is a common issue and may have been the cause of the other case you mention. We do provide advice on this in the instructions and in the FAQ (there is a section on 'MY SOFA HAS A HEARTBEAT!') which discusses this. To be clear, we do not manipulate anything within the app, if we did everyone would give us a 5* rating and perfect results, and that isn't the case and is why our rating is only 4/5. We do offer support to all our customers through the GET SUPPORT button and we're always happy to help and discuss any issues and help where we can. We're very sorry you've had a bad experience with the app, with best wishes, The HMB Team.
It works! No seriously

I’m 12 wks pregnant, & I was skeptical when I downloaded this app because I had been unsuccessful with finding my baby’s heartbeat using other free apps. I tried for about an hour at first, but couldn’t find baby at all. I didn’t get discouraged bc I knew baby was doing fine. I decided to take a break & try once more before bed. I found the heartbeat within 10 minutes on the second try! I can’t explain it, but I knew what it was instantly after hearing. I will say that one sign of successfully locating the heartbeat was seeing the steady rhythm being shown on the screen. If you don’t know what to listen for, look for that first and the sound will match! I also had a full bladder when I checked the second time so I think that helped. Don’t trust the free apps because I kept my phone on baby’s location and could not hear anything through them. This is the first time I’ve listened to a Facebook ad and paid for an app... ever lol. Also my first app review so it’s definitely worth it!

This is my third child, and the hardest pregnancy. Might be because of Covid, the world, idk but I’ve had a lot of complications and had a few high risk appointments for this baby. He’s all fine now but I’m paranoid, after two girls this is our boy so we’re excited. Baby’s movements have gotten slower since he has less room, also by this week he has developed some sleeping patterns so when I know he should be most active and isn’t Thats when I freak out. I have easily spent and wasted more than 5 bucks on in app purchases on other games, so I figured why the heck not try this. IT WORKS, I found my steady heartbeat after a min, found baby’s heartbeat after 5. His is obviously faster than mine and harder to find because idk what position he’s in. Following instructions helps, being further along helps too and patience. I’m happy with my purchase and will recommend this app to any friends that are expecting, worth the 4.99 :) thank you to the developers and staff.
