HRV Health
The vision

HRV Health

Sounds like science fiction. It's science, not fiction.

HRV App

Heart rate variability - the science of measuring your health - accurately and reliably every day.

Heart Rate Variability (HRV) is great science. We did not invent it. We are perfecting it.

HRV is the measure of health. The higher the numbers, the better your health.

Good health is part genetic and mostly good lifestyle. People who exercise regularly, eat healthy, sleep well, and look after themselves have high HRV, and are rarely ill. People who smoke, have poor diets, lead sedentary lives, drink too much alcohol have low HRV and this shows in their medical history and quality of life in retirement.

HRV drops with age, and improving HRV is the way to reverse the aging process. With the HRV Health Pro app you can measure your progress.

Athletes have been using HRV for years to measure the impact of rigorous training on their systems, adapting their training regimen according to what their HRV data says. When they are overtrained, the HRV figure will tell them that it’s time to take a break. When they’re on a good day, the data gives them the confidence to push that little bit harder.

People with health conditions are advised to change their lifestyles. The HRV metrics tell them when the changes are working.

Crucial to the validity of the results are the quality of the data acquisition equipment and the reading conditions. This is the foundation of our thinking. The apps only link to the Polar H9 and H10 heart rate monitors, and we look for indicators that warn if the reading is taken in less than ideal conditions.

The philosophy creates trust - crucial for decision making based on the results.

HRV Health has a web based platform where users can see all of their results. But not everyone wants all that information every day. The HRV Health Pro app is designed for people who care about their health, love and trust the guidance that the HRV Health results give them, and want to see their data and graphs on their mobile device.

Our app also allows users to take ECG readings. One day soon, doctors will say: “Just send me your HRV Health ECG graph.”

It is here now, and it works.

The HRV Health Platform gives its users the ability to measure their health and fitness with heart rate variability and resting heart rate as the scientifically proven advantage that elite athletes use to dominate their sports.

Your heart is your personal pathologist

Resting heart rate and heart rate variability (HRV) are metrics that give consistent feedback on our health status and fitness.

The Healthcare Crises

Healthcare costs are rising at an unsustainable rate. In America they are already 16.8% of GDP. The other rich economies are on the same trajectory.

Frequently asked questions

What is the price of the HRV Health services?
The basic HRV Health services are free for non-corporate users. The premium services, including ECG readings, Poincaré plots, and reading interpretations are only available to subscribers. Read: Why HRV Health is free

The HRV Health Apps work with the Polar H9 and H10 heart rate monitors. The Polar H10 HRM is required to take ECG readings. Read: Which heart rate monitor should you get
Why do I need a chest heart rate monitor?
HRV is measured in milliseconds. Only chest heart rate monitors that use ECG technology can provides heart beat data at this level of accuracy. Read: Your heart is your personal pathologist
What do the HRV numbers mean?
There are a range of metrics that are derived from the HRV data. The most important figures are the rMSSD, the ratio, stress, and the resting heart rate Read: Understanding the numbers
How do I improve the HRV numbers?
Lifestyle impacts HRV figures. Exercise, relaxation, a health diet, and good sleep all have a positive impact on the metrics. Stress, poor sleep, poor diet, excessive alcohol intake, smoking, and a sedentary lifetyle have affect the HRV resutls negaitively. Read: Improving the numbers
How do I take accurate readings?
The most accurate readings are obtained when you are close to your resting pulse rate. Measuring first thing in the morning is the best way to obtain the baseline. Ensure that you are comfortable. Avoid distraction: the news, emails and conversation will all impact the reading, usually negatively. Once you have established a baseline, feel free to experiment with other times of the day, always ensuring the the resting heart rate is a realistic proximation of the baseline. Read: Measuring HRV
How do I use the Poincaré plot?
The Poincaré plot should be cigar shaped, from bottom left to top right. Random reading points may be casue for concern. A highly concerntrated circle shaped Poincaré plot is an indicator of poor health and the existence a chronic condition that requires urgent medical attention. Read: Understanding the Poincaré plot
I am recovering from a serious medical condition. Can I use HRV to measure my progress towards recovery?
Yes. The steps towards recovery will display with improved HRV numbers. Sleep is crucial to recovery, as is exercise. A serious illness is a reminder of our mortaility, and the HRV numbers will reflect how seriously we take the warning. Read: Recovering from illness or injury using HRV
What is the purpose of the information that is required during registration?
The name is required as a courtesy for correspondence. HRV is age and gender dependent which the reason for the birthdate and gender. The email address is required for correspondence, and for sending to backups of your data. Read: Using the HRV Health Pro app

How do I know if I am overtraining?
Overtraining is a syndrome, and it shows up in the HRV results like an illness. Overtraining can have a long term impact on your ability to reach your goals. Look for the warning signs in your HRV results. Subscribers have access to recovery advisories, designed to optimize your training, and ensure that you avoid overtraining. Read: HRV and overtraining
How does HRV work?
Heart rate variability or HRV is the measure of your immune system. It is the measure of the interval between each heart beat over a period of time. (IBI) The greater the variability between the heart beat intervals, the healthier the immune system. Read: Your heart is your personal pathologist
This is a fascinating subject. What should I read to understand more?
We have compiled a list of articles that will bring you up to speed quickly. Read: HRV Health: what should you read?
How do I get started with HRV Health?
You need to have a Polar H9 or H10 HRM to take the readings. Once you have the HRM, install the HRV Health app, and register on the HRV Health platform. Then you are ready to start taking readings. It is important to establish the baseline of your health before interpreting the results. Take readings each morning for five days, and the metrics will give you an indication of your state of health. Read the articles about what the numbers mean, and how to improve them.

How to use the HRV Health PlatformIf you want to get the most out of the HRV Health Platform, you need to understand what the numbers are telling you, in the context of why you are measuring HRV. Some people use heart rate variability to improve sports performance, some use it to measure health, and some use it for both.
Starting out with HRV HealthHeart rate variabiolity lets people see themselves in a new and fascinating way. It becomes a voyage of self exploration. We encourage our users to make their discoveries.
Improving the numbersImproved health produces improved HRV results. This is a case study of how to get healthier.
The benefits of measuring Heart Rate VariabilityHeart rate variability gives users a daily measure of their health status. It also provides the elite athlete with a powerful metric of how their body is responding to training. 
HRV and ageingAge is a disease. That's Dr David Sinclair’s point. It has all of the symptoms of a disease, and the only reason that it’s not classified as a disease is because everyone suffers it.
Reversing ageing with HRVAs we get older our health deteriorates. Heart Rate Variability (HRV) measures health, and that decline in health appears as lower HRV.
Breathing to improve your healthWe’re always interested when any of our users start getting better HRV numbers. This is how they are doing it.
What to do when you are illWhat do you do when your HRV figures plummet and you don’t feel well. Low HRV figures are a signal. Athletes see it when they take a reading immediately after an intense workout. Post workout readings are dramatic. The reading an hour later shows the powers of recovery, with numbers often better than the morning reading.

Testimonials:
2021-10-04 06:42:54Glenda BBeing interested in my own health and wellness I was keen to learn how HRV might provide new insights.
Using the HRV Health app has given me more and different data to learn about myself. I’ve found that looking at my average HRV scores, stress index metrics and thinking about my overall health has already helped inform my choices about training and lifestyle.
2023-01-22 15:16:29arthur vSunday January 22, 2023 At the end of December 2021 I was looking for an app to improve my performance as an endurance athlete. I found HRV Health app. At first I was very skeptical because the RMSSD was extremely high and then very low again. The same with ratio, etc. , even though always felt well. I regularly received the messages from the app: Please contact a specialist. At first I thought there was a problem with the app. Nevertheless, I discussed the problem with Roy (HRV specialist) several times. I finally went to the heart specialist/cardiologist in May 2022, who actually diagnosed heart problems. In the summer of 2022, I had 2 stents implanted. I am fully active again as an endurance athlete since December 2022. I credit the HRV Health app and Roy's help for discovering my heart problems. I continue to use this app every day to check. Many thanks.. Arthur
2021-10-07 12:54:04Paul BI've been interested in HRV for some years now but have struggled to find a solution that is cost effective, non-proprietary and one that provides accurate and detailed information to help me take actionable steps to improve my health. Most solutions available on the market are focused on fitness, exercise and training, whereas my interests are much wider than this. The HRV system from HRVHealth.org gives me just that. The HRV system from HRVHealth.org gives me just that. I am able to use my Polar H10 heart rate strap to take daily readings, receiving immediate feedback regarding my HRV score for the day along with lots of other useful, related information such as my stress levels and how my readings compare to the wider population averages. It also allows me to record useful notes so that I can look back on readings and recognise patterns in lifestyle habits and how they impact on my HRV score. It provides an invaluable insight into my health and is a key tool in my 'wellness' armoury!
2021-10-04 19:06:11Pete WAs an amateur athlete I have found HRV to be an invaluable tool in monitoring my health and well-being.
After the initial setup, pairing and taking the reading is fast and simple. The data is easy to understand and the results give me another level of information on whether or not I’ll be in a great place to push myself. An additional bonus is, being highly competitive, I understand the decisions I make effect the HRV results so am constantly questioning the lifestyle decisions I make.
I believe HRV Health is an invaluable resource in documenting my health through heart rate variability and look forward to the long term outcomes.

HRV data not uploaded to systemCheck that the iOS device is connected to the Internet press the Start reading button.
New HRV reading does not appear on systemCheck that the iOS device is connected to the Internet, and click the New reading button. The haptic feedback will confirm that a new reading has been registered.
Results do not appear for the reading.On the HRV data screen, make sure that the Select checkbox is ticked, and click the Update button.
No readings.Is the HRM correctly attached to the chest.
There is no haptic tap when the reading starts or when it ends.Check that haptics are enabled in the iOS settings.
Haptics are enabled, but there is still no haptic feedback when readings are taken.Check that the device is connected to the Internet.
No readingsCheck that the bluetooth for HRV Health has been enabled in your phone settings.
No readingsIf you are using an iOS device, check that the app is communicating with the platform. After clicking start reading, the platform confirms the connection, and the iOS device gives haptic feedback.
The results appear to be wrongIf a reading appears to be incorrect, check that the # data points column is between 118 and 120. If it is not, take a new reading.
The results appear to be wrongLook at the resting heart rate and the HRV heart rate. If this differs by more than 5, take a new reading.
The results appear to be wrongLook at the respiration rate. If this is above 12, take a new reading, breathing slowly.
RHR pulse rate is higher than normal, respiration rate it higher than normal, feeling fine, but the results are lower than normal.This is a sign that you are potentially fighting an illness. Do not do any strenuous exercise, and look for other symptoms that you are not feeling well. Take a second reading.
Pressing the Results button produces a blank screenThe HRM device ID has not been registered on the HRV Health Platform. Login at https://hrvhealth.org/login.php#tabs-2 and add the device ID: on the menus Metrics->User setup->HRM device add.
Some of the buttons are yellow from the previous readingOn completion of a reading, the buttons should be restored to the Off state (Blue). Restart the app on the iOS device to restore the startup condition.
The time on the readings is out by an hour.The system is set up to adjust by an hour for daylight savings. In those countries that do not have daylight savings, the readings are out by an hour during winter.
The heart rate jumps around, and is inconsistentThis occurs with users of older iPhones. It does not have any impact on the data. If this bothers you, use the HRV Health Basic app.
The results are very unusual with an RMSSD of over 300. The Poincaré plot is widely dispersed.Take an ECG reading. If this is normal, check the battery status using the Polar Beat app. If the battery is low, replace the battery and take another reading.
The ECG reading appears to be inverted, with the spike going downwards instead of upwards.The Polar heart rate monitor is upside down. Please remove the device from the strap, and replace it on the strap with the device ID on top, and Polar logo right way up.
The registration has been successful, but unable to take ECG or HRV readings.We have been working with Polar on this issue. This investigation has uncovered worldwide marketing of non-Polar devices acting as Polar heart rate monitors. You are requested to contact Polar customer care at: customercare@polar.com with the subject: Illegal Polar device. They will assist you in resolving this problem.

1 Heart rate variability Standards of measurement, physiological interpretation, and clinical useThe phenomenon that is the focus of this report is the oscillation in the interval between consecutive heart beats as well as the oscillations between consecutive instantaneous heart rates. ‘Heart Rate Variability’ has become the conventionally accepted term to describe variations of both instantaneous heart rate and RR intervals. In order to describe oscillation in consecutive cardiac cycles, other terms have been used in the litera- ture, for example cycle length variability, heart period variability, RR variability and RR interval tachogram, and they more appropriately emphasize the fact that it is the interval between consecutive beats that is being analysed rather than the heart rate per se. However, these terms have not gained as wide acceptance as HRV, thus we will use the term HRV in this document.Task Force of The European Society of Cardiology, The North American Society of Pacing and ElectrophysiologySelect
2 Measurement of Heart Rate Variability: A Clinical Tool or a Research Toy?Before the measurement of HR variability can be applied to clinical practice and used to direct therapy, more precise insight into the pathophysiological link between HR variability and mortality are needed. Further studies should also address the issue of which of the HR variability indexes, including the new nonlinear measures, is best for clinical purposes in various patient populations.Heikki V. Huikuri, Timo Ma ̈kikallio, K. E. Juhani Airaksinen, Raul Mitrani, Agustin Castellanos, Robert J. MyerburgSelect
3 THE SOCIAL READJUSTMENT RATING SCALEIt has been adduced from these studies that this clustering of social or life events achieves etiologic significance as a necessary but not sufficient cause of illness and accounts in part for the time of onset of disease. Methodologically, the interview or questionnaire technique used in these studies has yielded only the number and types of events making up the cluster. Some estimate of the magnitude of these events is now required to bring greater precision to this area of research and to provide a quantitative basis for new epidemiological studies of diseases. This report defines a method which achieves this requisite. THOMAS H. HOLMES, RICHARD H. RAHESelect
4 Reduced Heart Rate Variability and New-Onset HypertensionHRV is reduced in men and women with systemic hypertension. Among normotensive men, lower HRV was associated with greater risk for developing hypertension. Estimation of LF using spectral analysis of ambulatory ECG recordings improves the prediction of risk of hypertension in men above that which can be obtained from measurements of baseline systolic and diastolic blood pressures, body mass index, and age. These findings are consistent with the hypothesis that autonomic dysregulation is present in the early stage of hypertension.Jagmeet P. Singh, Martin G. Larson, Hisako Tsuji, Jane C. Evans, Christopher J. O’Donnell, Daniel LevySelect
5 Short-Term Heart Rate Variability—Influence of Gender and Age in Healthy SubjectsFurthermore, there were significant modifications according to age in nearly all of the domains. The gender differences disappeared within the last two age decades and the age dependencies disappeared in the last decade. To summarize gender and age influences need to be considered when performing HRV studies even if these influences only partly differ.Andreas Voss,Rico Schroeder,Andreas Heitmann,Annette Peters,Siegfried PerzSelect
6 Twenty-Four Hour Time Domain Heart Rate Variability and Heart Rate: Relations to Age and Gender Over Nine DecadesConclusions. 1) Using all measures, HRV of healthy subjects declines with aging, with measure-dependent patterns. 2) Using the SDNN index, rMSSD and pNN50, HRV of healthy subjects, particularly those >65 years old, may decrease to below levels associated with increased risk of mortality. 3) Gender influences HRV. Gender differences in HRV are age and measure dependent. 4) Age and gender also affect heart rate.KEN UMETANI MD,DONALD H. SINGER MD FACC, ROLLIN MCCRATY MS, MIKE ATKINSONSelect

9 An Overview of Heart Rate variability Metrics and NormsThe authors survey published normative values for clinical, healthy, and optimal performance populations. They stress the importance of measurement context, including recording period length, subject age, and sex, on baseline HRV values. They caution that 24 h, short-term, and ultra-short-term normative values are not interchangeable. They encourage professionals to supplement published norms with findings from their own specialized populations. Finally, the authors provide an overview of HRV assessment strategies for clinical and optimal performance interventions.Fred Shaffer, J. P. GinsbergSelect
10 The Social Readjustment Rating ScaleThis Social Readjustment Rating Scale was created by Thomas Holmes & Richard Rahe, University of Washington School of Medicine, in the late 1960s to provide a standardized measure of the impact of a wide range of common stressors. Using the Scale To use the scale, simply add up the values for all of the listed life events that have occurred to you within the past year. If a particular event has happened to you more than once within the last 12 months, multiply the value by the number of occurrences. Enter your value total at the end of the list. The Scale Each life event is assigned a value in arbitrary “life changing units” chosen to reflect the relative amount of stress the event causes in the population studied. Stress is cumulative, so to estimate the total stress you are experiencing, add up the values corresponding to the events that have occurred in your life over the past year. Thomas Holmes, Richard RaheSelect
11 Effects of age and physical activity on the autonomic control of heart rate in healthy menThe interaction between aging and life-style effects had a P < 0.05. These results suggest that aging reduces HR variability. However, regular physical activity positively affects vagal activity on the heart and consequently attenuates the effects of aging in the autonomic control of HR.R C Melo, M D B Santos, E Silva, R J Quitério, M A Moreno, M S Reis, I A Verzola, L Oliveira, L E B Martins, L Gallo-Junior, A M CataiSelect
12 Heart-rate variability: a biomarker to study the influence of nutrition on physiological and psychological health?Aspects of diet that are viewed as undesirable, for example high intakes of saturated or trans-fat and high glycaemic carbohydrates, have been found to reduce HRV. It is argued that the consistent relationship between HRV, health and morbidity supports the view that HRV has the potential to become a widely used biomarker when considering the influence of diet on mental and physical health.Hayley A Young, David BentonSelect

14 Possible mechanisms of sudden cardiac death in top athletes: a basic cardiac electrophysiological point of viewUnless autopsy findings establish the exact cause of sudden cardiac death in an athlete beyond any doubt, the reasons should be sought in repolarization abnormalities rather than in an unconfirmed ischemic origin. Accordingly, more attention should be paid to noninvasive cardiac electrophysiological investigations during preventive sports medicine activities and to the theoretical and practical cardiac electrophysiological postgraduate training of sports doctors. Importantly, unexpected and unexplained syncopes in the anamnesis of athletes should be taken seriously and thoroughly investigated.András Varró, István BaczkóSelect
15 Underlying Medical Conditions and Severe Illness Among 540,667 Adults Hospitalized With COVID-19, March 2020–March 2021Among 4,899,447 hospitalized adults in PHD-SR, 540,667 (11.0%) were patients with COVID-19, of whom 94.9% had at least 1 underlying medical condition. Essential hypertension (50.4%), disorders of lipid metabolism (49.4%), and obesity (33.0%) were the most common. The strongest risk factors for death were obesity (adjusted risk ratio [aRR] = 1.30; 95% CI, 1.27–1.33), anxiety and fear-related disorders (aRR = 1.28; 95% CI, 1.25–1.31), and diabetes with complication (aRR = 1.26; 95% CI, 1.24–1.28), as well as the total number of conditions, with aRRs of death ranging from 1.53 (95% CI, 1.41–1.67) for patients with 1 condition to 3.82 (95% CI, 3.45–4.23) for patients with more than 10 conditions (compared with patients with no conditions).Kompaniyets L, Pennington AF, Goodman AB, Rosenblum HG, Belay B, Ko JY, et al.Select
16 Comparing SARS-CoV-2 natural immunity to vaccine-induced immunity: reinfections versus breakthrough infectionsThis study demonstrated that natural immunity confers longer lasting and stronger protection against infection, symptomatic disease and hospitalization caused by the Delta variant of SARS-CoV-2, compared to the BNT162b2 two-dose vaccine-induced immunity. Individuals who were both previously infected with SARS-CoV-2 and given a single dose of the vaccine gained additional protection against the Delta variant.Sivan Gazit MD MA12*, Roei Shlezinger BA1, Galit Perez MN MA2, Roni Lotan PhD Asaf Peretz MD Amir Ben-Tov MD Dani Cohen PhD4 Khitam Muhsen PhD, Gabriel Chodick PhD MHA, Tal Patalon MDSelect
17 healthy heart is not a metronome: an integrative review of the heart's anatomy and heart rate variabilityThe authors conclude that a coherent heart is not a metronome because its rhythms are characterized by both complexity and stability over longer time scales.

19 RESTING HEART RATE VARIABILITY AS A POSSIBLE MARKER OF COGNITIVE DECLINESignificant correlations in each cognitive function were found, except for processing speed, suggesting a positive association between resting HRV and cognitive performance. Mechanisms underlying this association between cardiovascular health and cognition are discussed. For the future, HRV could be used in diagnostics as an indicator of cognitive impairment before symptoms of dementia get apparent. With a timely diagnosis, preventative tools could be initiated at an early stage of dementia.Bernhard Grässler, Anita Hökelmann, Richard Halti CabralSelect
20 Heart rate variability – a historical perspectiveWith the measurement of the ECG (1895) and advent of digital signal processing techniques in the 1960s, investigation of HRV and its relationship to health and disease has exploded. This essay will conclude with a brief description of time domain, frequency domain, and non-linear dynamic analysis techniques (and their limitations) that are commonly used to measure HRV.George E.

  • Statistics of HRV & RHR trends among policyholders
  • Statistics of HRV & RHR trends among policyholder groups
  • Bespoke analysis of policyholder data

The objective of the pilot study is to conduct a trial during which the insurer can see the benefits of HRV Health.

  • Methodology
    • The insurer provides a group of volunteers (participants) who will use the HRV systems for a one month period
    • The insurer provides each participants with a Polar H10 heart rate monitor (HRM)
    • Each participant registers on the HRV Platform (the platform) and including registering their HRM device ID
    • Each participant installs the HRV Health app (the app) on their mobile device, and registers their HRM device ID on the app
    • Readings take approximately three minutes each mornings before eating, drinking any beverage, or any activity
    • For the duration of the field study (the duration), participants will take HRV readings daily, following best practice
    • Participants who fail to take readings daily will receive reminders
    • The insurer will receive notification of participants who fail to take daily readings
  • Reports
    • After one week, HRV Health will provide the insurer with a report, setting out details of the relative health and fitness of each of the participants
    • On completion of the field study, HRV Health will provide the insurer with a report setting out details of improvement/ deterioration in the health and fitness of each of the participants, and whether they are maintaining a healthy lifestyle
    • After providing the report, HRV Health will obtain confirmation from the participants of the accuracy of their findings, and provide this feedback to the insurer
  • Cost
    • The cost of the HRMs is for the insurer
    • The one month field is offered free of charge
    • Extended field studies of more than one month will be chargeable, at negotiable rates

HRV Health Team

Meet the team:

The founder: Roy Reto Dalle Vedove BAcc MBA

Roy R Dalle Vedove

Roy is a forensic accountant specialising in big data. He spent a good deal of his career developing algorithms, particularly in insurance, that enriched his clients.

On moving to Switzerland, he discovered that not only is health insurance mandatory and exorbitant, it does not follow the basic insurance principle that higher risk carries a higher premium.

To say that Roy is low risk is understatement. He cycles daily, and has the resting heart rate (RHR) of an athlete, just below 40bpm.

Early in 2020, he started a conversation with his health insurer about using RHR to categorise the risk profile of policyholders. They agreed. Nothing happened.

Then he discovered heart rate variability (HRV). At first it started as an academic exercise. The research uncovered that HRV has been used for decades as a health measure, and that the international standards for the metrics were established in 1996.

His own experience with HRV and RHR  proved that the efficacy of the technology.

“We have the data to determine which percentile of health and fitness a person is in, relative to the population.” he says.

Now he’s talking to health insurers globally about using RHR and HRV to reward customers who adopt a healthy lifestyle.

When asked what he’ll do if the insurers don’t employ the idea, he’s coy. “We have a plan B”.

1 Sunday January 22, 2023 At the end of December 2021 I was looking for an app to improve my performance as an endurance athlete. I found HRV Health app. At first I was very skeptical because the RMSSD was extremely high and then very low again. The same with ratio, etc. , even though always felt well. I regularly received the messages from the app: Please contact a specialist. At first I thought there was a problem with the app. Nevertheless, I discussed the problem with Roy (HRV specialist) several times. I finally went to the heart specialist/cardiologist in May 2022, who actually diagnosed heart problems. In the summer of 2022, I had 2 stents implanted. I am fully active again as an endurance athlete since December 2022. I credit the HRV Health app and Roy's help for discovering my heart problems. I continue to use this app every day to check. Many thanks.. Arthurarthur2023-01-22 15:16:29
2 I've been interested in HRV for some years now but have struggled to find a solution that is cost effective, non-proprietary and one that provides accurate and detailed information to help me take actionable steps to improve my health. Most solutions available on the market are focused on fitness, exercise and training, whereas my interests are much wider than this. The HRV system from HRVHealth.org gives me just that. The HRV system from HRVHealth.org gives me just that. I am able to use my Polar H10 heart rate strap to take daily readings, receiving immediate feedback regarding my HRV score for the day along with lots of other useful, related information such as my stress levels and how my readings compare to the wider population averages. It also allows me to record useful notes so that I can look back on readings and recognise patterns in lifestyle habits and how they impact on my HRV score. It provides an invaluable insight into my health and is a key tool in my 'wellness' armoury!Paul2021-10-07 12:54:04
3 As an amateur athlete I have found HRV to be an invaluable tool in monitoring my health and well-being.
After the initial setup, pairing and taking the reading is fast and simple. The data is easy to understand and the results give me another level of information on whether or not I’ll be in a great place to push myself. An additional bonus is, being highly competitive, I understand the decisions I make effect the HRV results so am constantly questioning the lifestyle decisions I make.
I believe HRV Health is an invaluable resource in documenting my health through heart rate variability and look forward to the long term outcomes.

4 Très bonne application qui permet de voir son état de fatigue et de stress. Un bon indicateur de la forme physique et du status de la récupération. Utilisé jour après jour afin de savoir quand lever le pied. Site riche en documentations, très instructif avec un blog très pertinent. Du Swiss made, simplement excellent. Stanstan2023-02-19 19:06:39
5 Being interested in my own health and wellness I was keen to learn how HRV might provide new insights.
Using the HRV Health app has given me more and different data to learn about myself. I’ve found that looking at my average HRV scores, stress index metrics and thinking about my overall health has already helped inform my choices about training and lifestyle.
