Rytmo

Delivering continuous heart monitoring through a wearable-powered app

Real-time cardiovascular data in dashboards users can share with doctors

About the project

Rytmo is a mobile-first solution developed with a major corporate research laboratory. It integrates wearable biosensing technology and advanced machine learning models to provide real-time cardiovascular monitoring. 

The system connects to custom hardware devices (OmniBuds) via Bluetooth, collects physiological data, and processes it locally on the smartphone for privacy. Users can view intuitive dashboards, generate reports, and securely share insights with healthcare providers.

Challenge

The Rytmo team aimed to bring continuous heart monitoring out of hospitals and into daily life. Fragmented, complex tools missed critical health events between visits, so they needed a patient-first, privacy-focused solution with real-time insights and seamless end-to-end delivery.

Our process

A research prototype only matters if patients can trust it. So, our focus was turning that science into a mobile solution people could rely on every day, positioning the product for real-world adoption and long-term market advantage.

Results

The Rytmo MVP showed that continuous heart monitoring is possible through a simple, wearable mobile device. Patients easily paired devices, collected biosignal data, and viewed reports without training — crucial for real-world use. Although external KPIs are still being developed, the solution has moved beyond concept, showing strong potential for wider healthtech use and future clinical collaborations.
