Big news! Most Stethophone Pro features (besides AI) are now available to everyone without a prescription.

Stethophone Pro, our flagship medical device, has received another FDA 510(k) clearance, meaning the U.S. Food and Drug Administration has formally cleared the product’s use as a medical tool.

This clearance opens the door for broader access to advanced cardiac assessment directly on a smartphone.
☝For users, that means Stethophone Pro’s capabilities are now more widely available - empowering both clinicians and everyday people to collect and share high-quality cardiac sound data wherever they are.

Our mission is to make state-of-the-art cardiac screening as simple and accessible as using a smartphone.
The future of proactive care is here.

Let’s get back to basics: heart disease screening isn't just a box to tick—it's your early warning system. We’re taking a closer look at why screening for valve health, in particular, is one of the most proactive steps you can take for your heart.

One in 40 Americans lives with heart valve disease, and risk rises sharply after age 65.

👇The solution?
Stethophone makes screening quick and accessible from any smartphone. Its FDA‑cleared technology helps detect valve disease early, especially in older adults who may not show symptoms, supporting timely care and better long-term outcomes.

Screening is key! Heart valve disease is a growing global burden, and early detection is critical to improving outcomes. ☝

The American Heart Association initiative focuses on closing the gap in timely diagnosis and treatment of heart valve disease. By standardizing screening recommendations, improving provider awareness, and promoting early intervention, the AHA aims to reduce preventable complications and hospitalizations, ensuring patients receive care before the disease progresses to severe stages.

Stethophone, an FDA-cleared Class II medical device for VHD screening, makes advanced cardiac assessment accessible by transforming everyday smartphones into reliable heart evaluation tools–removing barriers related to equipment, training, and clinical access.

We, Sparrow BioAcoustics, were pleased to join the American Heart Association’s Innovators’ Network this year, collaborating through the AHA Center for Health Technology & Innovation. As part of this consortium, we’re working alongside other health tech leaders to advance earlier and more equitable detection of cardiovascular conditions, aligned with AHA’s goals of accelerating innovation and improving outcomes for people living with heart disease.

How do we reach treatment sooner – for all people, everywhere?
�☝ This question sits at the heart of the American Heart Association’s mission to close the detection gap in heart valve disease.
The first and most critical step is identifying the murmur.� Yet millions of people with valve disease remain asymptomatic, meaning symptom-based diagnosis often comes too late.
Stethophone addresses this gap by turning any smartphone into an FDA-cleared heart valve disease screening tool. It enables fast, accessible, proactive screening before symptoms appear – helping clinicians and health systems move diagnosis earlier and improve outcomes at scale.

💙 Heart sounds can be analyzed not only by listening

🎯 A spectrogram makes it possible to visualize heart sounds in the time–frequency domain, significantly expanding the possibilities of clinical analysis. It helps detect very subtle acoustic phenomena, including low-frequency murmurs and gallop sounds (S3, S4), which are often difficult or impossible to identify by auscultation alone.

A spectrogram shows the frequency composition of the sound and its distribution over time, allowing clinicians to better distinguish pathological signals from artifacts.

For comprehensive clinical analysis, the spectrogram is used together with an oscillogram. It is the combination of these methods that improves diagnostic accuracy.

This post is based on an article by Yaroslav Shpak, Chief Medical Officer at Sparrow BioAcoustics, where he shares key insights on the use of spectrograms for heart sound analysis.

🎉 What a year! 2025 was about validating our impact and forging powerful alliances at Sparrow Bioacoustics.

Beyond the honors and awards, our greatest achievements are the partnerships that will drive real-world change.

Our collaboration with the @ American Heart Association is one of the milestones. Together, we are co-developing pathways to integrate Stethophone into cardiovascular care, aiming to make early detection truly accessible.

To ensure our technology meets the highest clinical standards, we are incredibly proud that leading physicians and medical experts have joined our Clinical Board. Their frontline expertise is invaluable in shaping solutions that directly address patient and clinician needs.

🫂A special and heartfelt thank you goes to all our users of Stethophone. Your trust and daily use of our technology are the ultimate validation of our work and the driving force behind our mission.

This video highlights a year of building the foundation for what’s next. 🙌❤️

Stethophone has patented advanced bioacoustics that make heart sounds clearer and more audible. The application records sound with the best possible accuracy which allows detection of all symptoms and the highly efficient analysis with AI-algorithms.

Recordings undergo automated medical quality checks before AI-assessment. The system amplifies the sound, but simultaneously identifies and softens loud artifacts, which can be unpleasant with high amplification and interfere interpretation.

These steps preserve diagnostic value and ensure that downstream analysis reflects true physiology rather than contamination or distortion.
