Ultrasound app on your phone: what's really out there?

Important notice: no app can perform an ultrasound using only a cell phone. The exam depends on a transducer, the device that emits and receives sound waves — and cell phones don't have that. What does exist are portable probes for professional use, which cost thousands of reais and are sold to clinics and doctors, as well as apps that serve to store and interpret the images from the exam you've already had.

With the advancement of technology, many tasks previously limited to specialized clinics have gained home versions—but not all. One example of this is the (mistaken) idea of do ultrasound with your cell phone, using modern apps that offer visual and audio support for monitoring pregnancy or health in general. This innovation has been gaining prominence, especially among pregnant women who want to monitor their baby's development more closely.

While these apps are not a substitute for a traditional medical exam, they do offer valuable features. They can connect to external devices, simulate sensor-based images, or even allow you to view and organize real exams received from clinics. Below, you will learn about the three best options available for this.

In addition, some apps allow you to store and view exams performed in specialized clinics directly on your smartphone.

Avoid using uncertified apps that promise complete medical diagnoses without scientific validation. Opt for apps with good reviews and support from trusted manufacturers.

How to use it in practice

  1. Always register at the same time. Measurements taken under similar conditions are what allow for comparison. Also note the context: fasting, after exertion, on a stressful day.
  2. Use certified equipment when taking measurements. The cell phone doesn't measure; the equipment with sanitary registration does the measuring. The app only stores the number.
  3. Check out the privacy policy. Health data is sensitive data. Check if it is being shared with third parties and if it's possible to delete everything.
  4. Generate the report before the query. Exporting as a PDF and having it printed or on your phone greatly shortens the conversation.

What goes wrong most often?

  • Taking estimated steps, sleep, or calories as an exact measurement—that's an approximation using a motion sensor.
  • Changing medication dosage based on a number seen in the app.
  • Believing that a cell phone measures blood pressure, glucose, or body temperature is wrong; there is no sensor for that in the device.
  • Swap in-person consultations for apps — none of them provide diagnoses.

What the cell phone itself already does.

Android and iPhone already come with a native health app that consolidates steps, sleep, and measurements sent by other devices, with privacy controls by data type. It's usually the safest place to store your history, and you can export it to take to your doctor.
