When I was pregnant, safety was always my first concern. I remember wondering if it was really okay to use an app to listen for my baby’s heartbeat. Was it safe for the baby? Was it safe for me? Like so many parents, I wanted reassurance — not just from the sound I was hoping to hear, but also in knowing I wasn’t doing anything that could cause harm.

The good news is that apps like Hear My Baby are safe to use. They don’t use ultrasound waves, radiation, or anything invasive. Instead, they work in the same way a stethoscope does — by listening. The app uses only your iPhone’s built-in microphone to pick up sounds from your bump. That means there’s no transmission of energy into your body, just sound coming out.

What makes Hear My Baby different from many free apps is that it’s honest about what to expect. The app doesn’t pretend to be a medical tool. It doesn’t give diagnostic readings or replace checkups. It’s designed purely for bonding and reassurance. Most parents start to hear something from around 16 weeks, and the clearest results usually happen after 27 weeks. Before that, it can be hit or miss, which is why patience is important.

Here are a few reasons parents trust Hear My Baby as a safe choice:

  • No waves, no radiation, no risk. It uses only your iPhone’s microphone.

  • Non-invasive. Nothing enters the body, nothing touches the baby.

  • Clear about its purpose. It’s not medical, it’s for bonding and joy.

  • Loved by parents. Trusted by over 500,000 families worldwide.

One reviewer wrote: “I worried at first about safety, but once I realised it’s just listening like a stethoscope, I felt completely comfortable.” Another said: “It gave me peace of mind when I needed it, without any risk.”

So yes, baby heartbeat apps can be safe — but the key is choosing one that’s honest and designed for bonding. Hear My Baby gives you that reassurance in every sense of the word: safe to use, safe for your baby, and safe as a joyful memory to keep forever.
