Withings Introduces StethO Sense, Bringing Heart and Lung Sound Analysis to BeamO

Withings today announced StethO Sense, a new service within Withings+, the premium membership tier of the Withings app, that gives parents a closer listen to what their child's bodies are already saying. It brings on-demand AI-powered analysis of heart and lung recordings to BeamO, the company's compact, FDA-cleared health device that combines a clinical-grade thermometer, 1-lead ECG, and digital stethoscope in one tool.

Powered by eMurmur Heart AI for abnormal murmur detection, and StethoMe for breathing sound insights, StethO Sense provides BeamO users with the ability to analyze heart and lung recordings from the comfort of the home. Withings+ members can access unlimited analyses at home, with results available in seconds. StethO Sense results are not a diagnosis and are intended to be shared with a healthcare professional.

"Hearts don't always tell us when something is wrong. A heart murmur, an unusual sound caused by blood flowing through the heart, can go unnoticed for years. StethO Sense lets families record heart sounds at home, in seconds, as often as they want, and build a record they can bring to their doctor. It doesn't replace a visit; rather, StethO Sense gives you additional health data to bring to one," said Livia Robic, Product Manager, BeamO.

How StethO Sense Works
From the StethO Sense section of the Withings+ app, users can select a heart or lung recording and instantly start the analysis. Heart recordings are taken at one of four standard positions, while lung recordings are taken at up to eight positions at 12 years of age and above, and six positions for those below 12 years of age. BeamO guides users through the process with an anatomical diagram. Results are delivered within seconds in the Withings app.1,1b

StethO Sense complements the Withings+ Cardio Check-Up service, which provides a cardiologist review of a user's ECG within 24 hours, up to four times a year. The two services are complementary: Cardio Check-Up provides a cardiologist's review of an ECG, while StethO Sense provides unlimited AI-assisted analysis of heart and lung recordings that users can share with a healthcare professional.

Designed for Families and Everyday Health Monitoring
StethO Sense is designed to provide peace of mind to people who want additional insight into the health signals they can capture at home, including:

For children & families:

• Identify changes in breathing sounds: StethoMe's Breathing Index gives a score, 0–100, based on their breathing sounds, breathing quality, breathing rate, plus respiratory rhythm, and heart rate, helping families notice changes over time. It is designed to give insight into day-to-day breathing patterns and if necessary to be shared directly with a healthcare professional, with a report exportable from the Withings+ app.
• Track heart murmurs: StethO Sense lets parents record their child's heart sounds at home, tracking heart murmurs and changes in heart sounds. It is designed to be shared directly with a healthcare professional and a report is exportable from the Withings+ app.
• Spot early symptoms before an urgent care visit: StethO Sense also tracks changes in heart which is particularly important during winter months.

Adults monitoring their heart health:

• Track heart murmurs: Heart murmurs are relatively common, affecting nearly one in four adults.6 While many are harmless, murmurs can sometimes be an early sign of valvular heart disease, a condition that often develops silently and is easy to miss without a regular check. A 2024 study of over 4,200 older adults found that more than a quarter had valvular heart disease that had never been diagnosed.7 StethO Sense gives users a way to record and track heart sounds over time, rather than only at an annual check-up, and to share those recordings with a healthcare professional.
• Athletes: StethO Sense is valuable for athletes as heart murmur checks are increasingly part of routine sports physicals, particularly in the US, where screening for conditions like hypertrophic cardiomyopathy (HCM), a leading cause of sudden cardiac events in young athletes, is a growing focus.

eMurmur: Heart Sound Analysis
StethO Sense's heart sounds analysis is provided by eMurmur2, a medical AI company that built an open intelligence layer to power auscultation hardware and software. eMurmur Heart AI analyzes BeamO heart sound recordings in seconds, and distinguishes between the absence of a murmur, innocent murmurs and abnormal murmurs. Across multiple blinded prospective clinical studies, eMurmur Heart AI demonstrated approximately 90% sensitivity and specificity for pathologic murmur detection.3 It also provides the heart rate and a confidence score for its findings. eMurmur Heart AI is FDA-cleared for use on both children and adults.4

StethoMe: Breathing Sound Insights
StethO Sense also brings a new Breathing Index from StethoMe,5a an AI company specializing in pulmonary sound analysis. The Breathing Index provides a score 0–100 based on breathing sounds and quality of breathing. It is designed to help people notice changes in their breathing patterns over time, with a guided protocol that adapts to age (six recording points for children, eight for adults). In the US, StethoMe's Breathing Index is offered as a general wellness feature.

Extending StethO Sense to Healthcare Professionals
StethO Sense also extends to BeamO PrO, the professional version of the device used by clinicians and care teams. With eMurmur's FDA-cleared Heart AI, healthcare professionals can perform heart sound assessments efficiently across a range of care settings, including nursing homes. AI-assisted auscultation has also been shown to reduce inappropriate cardiology referrals by up to 50–75%, helping care teams prioritize the patients who need further investigation. The technology is designed to support clinical workflows by providing additional information that can be considered alongside a healthcare professional's assessment.

Availability
StethO Sense will be available beginning October 1, 2026, exclusively for Withings+ users. To celebrate the launch, existing BeamO users who purchased their device before October 1, 2026 will receive a complimentary one-month trial of Withings+. Consumers purchasing BeamO for $249.95 starting October 1, 2026 will get a 1-month free trial of Withings+ to experience StethO Sense.
