We provide accurate and detailed HRV analysis for short- and long-term measurements and for all kinds of study protocols. Welltory supports both PPG and ECG measurements taken with BLE heart rate monitors like Polar, Apple Watch, Samsung HRM, and even your phone’s camera.

Welltory is an easy-to-use appResearch tools have never been so easy and accessible

There is no necessity to align huge budgets or buy special medical equipment. With Welltory, you only need participants with smartphones and a research license.

The invention of the scientific method and science is, I’m sure we’ll all agree, the most powerful intellectual idea, the most powerful framework for thinking and investigating and understanding and challenging the world around us that there is.

Why Welltory is a reliable HRV tracking tool

It was proved that Welltory is a valid and reliable smartphone application and can be used to monitor HRV among elite endurance athletes.

Our research team designs professional methods to analyze Photoplethysmography (PPG) measurements of heart rate variability using a phone camera.

We’ve also published research on our HRV signal processing and quality assessment method.

The accuracy of measurements taken with a smartphone camera has been proven — such measurements are on par with the Polar H7 chest strap.

One of the largest HRV databases in the world

Cases of how do global universities use the Welltory app in their studies

Welltory is an acknowledged app in scientific research, used at dozens of universities around the globe. We employ the full range of HRV measurements to collect accurate, large insights both qualitatively and quantitatively.

As a stress detection and management app

Twenty participants were conducted to study the effects of action planning in personal informatics with the example of a stress management app.

To enhance empirical evidence supporting the research on a campus therapy dog’s aid by explaining the dog’s effect on effect on nursing student stress.

In a randomized controlled pilot study among ten informal Alzheimer’s disease caregivers, we examined a two-week ten-minute daily, internet-delivered heart-focused breathing protocol compared to a waitlist control.

As an HRV monitor in a high-performance sports research group

Twenty-six professional cyclists in a resting state were measured in supine and in seated positions through the simultaneous use of an electrocardiogram and two different smartphone applications that implement different technologies to measure HRV: Elite HRV (with a chest strap) and Welltory (photoplethysmography).

As an HRV monitor for early prediction of COVID-19

One hundred eighty-six patients with more than, 3200 HRV readings and numerous user textual logs were analyzed by the AI framework to generate the final decision as either “potentially COVID-19 infected” or “no evident signs of infection”.
