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.

Halo Lab’s UI/UX design services for wearable heart monitoring

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.

Human-centered UX design services for healthtech by Halo Lab

Results

  • Patient-first UX design lowered the barrier to entry, letting patients use the app without any training or clinical guidance
  • Accessible interface made complex biosignal data easy to read and interpret
  • Stable BLE integration with OmniBuds hardware proved wearable connectivity works reliably outside the lab
  • The validated MVP opened the door to future clinical collaborations and broader healthtech adoption

Our approach

Strong results start with open dialogue. At every stage, we work closely with the client’s team, running workshops, gathering feedback, and refining ideas through multiple iterations. If your product needs the same level of care, contact us — and we’ll help turn complexity into an experience people can understand, trust, and use with confidence.

01 Discovery & product definition

We began by aligning with the client on the clinical vision, establishing a shared understanding of the product’s purpose and direction. Next, we mapped the platform’s key user groups — patients and healthcare providers — to understand how each would interact with the product.

Deliverables

  • Two target segments identified
  • Seven competitors analyzed

02 UX & mobile app design

We created patient-first wireframes and UI concepts that simplified biosignal interpretation for non-clinical users, using clean visuals, intuitive navigation, and onboarding guidance built around ease of understanding and everyday usability.

Deliverables

  • Two UI design concepts proposed
  • Elderly-focused accessible UI
  • Sensor data visualizations

03 Wearable integration & development

We built a cross-platform application with stable BLE pairing across devices, ensuring reliable data capture even in low-signal conditions. Local signal processing and modular backend services fed into ML-driven insights, transforming raw biosignal data into meaningful information.

Deliverables

  • ML & LLM integration
  • BLE pairing logic implemented
  • Privacy-first data sharing flows

04 Collaboration & iteration

Working closely with the research lab, we refined product flows through weekly reviews, adapting to new hardware requirements as they emerged and continuously testing signal quality to ensure reliable real-world performance.

Deliverables

  • Hardware-aligned flows finalized
  • Real-device stability validated
