Description

The only scientifically validated HRV app that doesn't require an external sensor. HRV4Training helps you optimize your goals and prevent overtraining by measuring your Heart Rate Variability and providing tailored feedback on your physical condition. HRV4Training does not require a heart rate monitor, since it can accurately assess your HRV using the phone's camera.

HRV4Training is also the first app that goes beyond simple measurements and provides insights on:
1) acute or day to day HRV changes in response to different stressors (alcohol, travel, sick days, training, menstruation, etc.)
2) long term multi-parameter trends to look at the big picture
3) correlations between physiological measurements and annotations
4) training load analysis, fitness, fatigue, readiness to perform and injury risk
5) VO2max estimation for runners linking the app to Strava or TrainingPeaks
6) Training Polarization analysis (or 80/20)
7) Weekly and monthly summaries to track progress.

All data is processed inside the app in order to provide you with actionable interpretations that can help optimizing your training plan and performance.

Supported devices for the camera measurement: iPhones 5, 5S, 6, 6S, 6+, 6S+, SE, 7, 7+, 8, 8+, X
Currently unsupported devices for the camera measurement: iPhones 4S, iPads and iPods - These devices require a chest strap.

Other features:
- HRV-based advice helps you to adapt your trainings based on objective measures of recovery
- TAGS: lets you tag your sleep, mental energy, muscle fatigue, stress and all other parameters that can help you understand what is influencing your physical condition and physiological stress
- Works with Bluetooth SMART heart rate monitors (a Polar H7 is recommended) or simply your phone's Camera
- Configurable test (single or orthostatic, choose test duration between 1, 3 or 5 minutes)
- Extracts and stores the following features while lying down and/or standing: heart rate, mean of beat-to-beat intervals (AVNN), standard deviation of beat-to-beat intervals (SDNN), square root of the mean squared difference of successive R-Rs (rMSSD), number of pairs of successive R-Rs that differ by more than 50 ms (pNN50), low frequency power (LF, 0.04-0.15 Hz), high frequency power (HF, 0.15-0.40 Hz)
- Shows the PPG signal view to ensure signal quality during the test if the camera is used instead of a bluetooth SMART sensor
- HRV4T Recovery Points to provide a single, straightforward metric to analyze your physical condition
- Population summaries and people like you comparisons to put your data into perspective
- Analysis of compliance and consistency
- Integrates with the Health app (writes heart rate, and sleep, read sleep time)
- Data export via email or Dropbox
- Integrates with TrainingPeaks, SportTracks, Genetrainer and Strava

The best app out there for HRV!

Beekaytab

What can I say I’m impressed. I’ve tested and downloaded several other HRV apps but they either required an external or didn’t support the new Apple Watch feature that supports HRV. Even though this app doesn’t support the Apple Watch either, it still offered the ability to use my existing iPhone. Don’t be fooled, the iPhone camera works just as great. I used to use the camera for other things to measure HR and I found it to be just as accurate. The HRV was spot on at least referencing against the Apple Watch readings.

As for the app, there are some bugs that I’ve worked with Marco to resolve so while minor he has worked with me. I do acknowledge that most of these HRV apps tend to favor runners, cyclists, or triathletes. Fitness and CrossFit folks are just as interested in peak training. Remember us too!

Lastly, the insights are great and this is the kind of easy advice I was looking for. Integration with other apps to include Strava and Training Peaks is a plus. A negative is the inability to get into the weeds with your data or edit but I just found out they have a Coach app that will allow you to do that and I might have to investigate that!

Overall very impressed and hope they keep developing this app.

Indispensable training tool

I’ve been using HRV4Training daily for almost a year now to track my heart rate and many other aspects of my health, life, and training. The app has become an indispensable part of my training process.

HRV4Training is based on reviewed, validated research, and Marco uses his personal expertise and his experience as a serious runner to make the app focused and effective. His blog posts about the workings of the app and the science behind it are a tremendous resource. And he’s been unbelievably available in answering questions and helping me fine-tune my usage of the app.

Doesn't align with me

Trail Runner 1138

Using the camera sensor on an iPhone, I find that my readings are very different than my subjective feeling. On days I know I'm well rested I get very low scores, and on days when I'm very tired I get my highest scores. I wish I could return this app after about a week of use, but since I can't, I submit this feedback instead. Buyer beware.

Also, if you're looking to sync with TrainingPeaks, note that it only sends it's proprietary score, not the standard hrv measurement. This may be useful to know if you have a history using other apps or devices. Of course, you can see the standard score on the app, but it doesn't push that number to TrainingPeaks.
