We’ve created the first tool for researching healthy lifestyles that is available to anybody with a smartphone.

Welltory is a free mobile app for iOS and Android that can be used by research participants to take daily measurements of their stress & energy levels, track the state of their nervous and cardiovascular systems, and collect data about physical activity, nutrition, mood, lifestyle, the weather, workouts, meditation, productivity, and medication. The researcher will get monthly or weekly reports that contain data on research participants in csv format sent to their email address. 

What are the benefits?

Welltory enables anybody with an iOS or Android to take heart rate variability measurements – all users need is their smartphone camera or a heart rate monitor.
Heart rate variability is a reliable, non-invasive method for measuring the condition of the autonomic nervous system and cardiovascular system. It is essentially a reflection of the person’s health – the balance between their sympathetic and parasympathetic nervous systems, which determine stress & energy levels.

Aside from stress & energy, the measurements track the complete list of parameters typically used in clinical research. There are 22,000+ studies based on heart rate variability on PubMed.


The most important thing to understand is that heart rate variability shows improvements or downturns in the body’s systemic condition for relatively healthy people under the influence of specific lifestyle changes or interventions.

Up until now, scientists had to get research participants in one place, supply them with expensive equipment, and take measurements on the spot. With Welltory, you will be able to conduct the same experiments without leaving your office or investing in expensive equipment. Moreover, you’ll be able to get together a group of research subjects of any size and from any country. All they need is a smartphone.

Scientists about HRV

Whenever you want to nurture innovation, you need to have metrics… The reason HRV was chosen was… for one, we have decades worth of heart rate variability data. There is good cohort data, population level data, that suggests that declining HRV is also due to a chronologic age [and] unlike most biomarkers in health, HRV can be measured continuously, contextually.You can measure it for 24 hours.
