Heartbeat App, Home Doppler and Ultrasound: What’s the Difference?
Phone apps, handheld Dopplers and ultrasound are often discussed together, even though their technologies, capabilities and levels of medical oversight differ. The most important rule is simple: an emotional recording made at home does not replace a clinical examination.

Bubbi uses the phone’s microphone, creates no image and emits no ultrasound. Its role is to help you listen, record, save and share an emotional moment. It does not confirm the source of a rhythm or assess health.
Home fetal Doppler
A Doppler is an ultrasound device. Even when sold for home use, it is easy for an untrained person to mistake the mother’s heartbeat or placental blood flow for the baby’s heartbeat. The FDA and NHS services warn about untrained use and misinterpretation.
Clinical ultrasound
Ultrasound is performed by a trained professional for a specific medical purpose. A standard exam may assess growth, position, movements, heart rhythm, the placenta, amniotic fluid and other factors. The result is interpreted in the context of the whole pregnancy.
Which option fits which purpose
For a keepsake and family ritual, a microphone-based app with a clear disclaimer may be appropriate. A medical question requires a clinician and the examination they recommend. A home Doppler is not an intermediate substitute for professional care.
What no sound recorded at home can do
It cannot rule out a problem, explain changed movements or assess the placenta or the baby’s development. If you are concerned, do not choose between an app and a Doppler—contact a healthcare professional.
Frequently asked questions
Is Bubbi a Doppler?
No. Bubbi uses a phone microphone, while a Doppler uses ultrasound.
Does Bubbi show an image of the baby?
No. An image is produced by ultrasound equipment during a medical examination.
What is reliable for assessing health?
Only professional medical assessment and appropriately ordered examinations.
