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 training 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.
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+
Currently unsupported devices for the camera measurement: iPhones 4S, iPads and iPods - These devices require a chest strap.
- HRV-based advice helps you to adapt your trainings based on objective measures of recovery
- Advanced insights on both short term acute responses to training and long term multi-parameter trends to better understand the big picture
- Training load analysis: pick the metric most representative of your trainings (e.g. TSS, Suffer Score, training distance or your own custom metric) and analyze fitness & fatigue, determined as chronic and acute training loads, as well as readiness to perform and injury risk.
- In app Correlations analysis between HR/HRV and annotated Tags
- 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
- Lets you annotate your training days and training intensity to provide more accurate analytics on how your trainings impact your physical condition
- 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
- Trends to look at the bigger picture
- Custom analysis on the relation between trainings and HRV
- Integrates with the Health app (writes heart rate)
- Data export via email or Dropbox
- RR-intervals correction
- Integrates with TrainingPeaks, SportTracks, Genetrainer (push data) and Strava (retrieve your trainings)

What's New in Version 6.6.9
- Strava: we fixed an issue that caused private activities not to be read correctly. If you'd like to keep your Strava profile private, make sure to re-link Strava in HRV4Training from Settings.
- Sleep tracking: fixed issue that caused data not to be read properly from third party devices through the Health app.
For any issues or questions, feel free to contact us at hello@HRV4Training.com - we cannot answer to reviews, so if you need help, just email us
If you like the updates, please take a few minutes to the review the app. It makes a difference. Thanks!
p.s. feel free to contact us if you’d like to take multiple measurement per day and experiment more. Happy to send you a promo code for the Camera HRV app so that you can download it for free.
