Description
The first scientifically validated Heart Rate Variability (HRV) app. HRV4Training provides HRV based insights to help you quantify stress,
better balance training and lifestyle, and improve performance. HRV4Training does not require a heart rate monitor, since it can accurately assess your HRV using the phone's camera.
HRV4Training also works with Apple Watch, the Oura ring and all compatible Bluetooth SMART sensors.
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 and using a heart rate monitor during their workouts
6) Training Polarization analysis (or 80/20)
7) Lactate Threshold Estimation for runners linking the app to Strava or TrainingPeaks and using a heart rate monitor during their workouts
8) 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, XS, XS Max, XR, 11, 11 Pro, 11 Pro Max, 12 mini, 12, 12 Pro, 12 Pro Max, 13 mini, 13, 13 Pro, 13 Pro Max, 14, 14 Plus, 14 Max, 14 Pro, 15, 15 Max, 15 Pro, 16, 16 Max, 16 Pro
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
- Integrates with the Health app (writes heart rate, and sleep, read sleep time)
- 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
- Data export via email or Dropbox
- Integrates with TrainingPeaks, Oura, Strava and Coros
HRV4Training requires to register an account with your email address, so that your data can be backed up safely and retrieved in case anything happens (app issue, changing phone, etc.).

Ratings and Reviews
Fantastic app
Don’t waste your money on whoop or oura, just get this fantastic app
Does not work reliably with watch
The app relies on breath by Apple. But the data is not reliably imported to the app. When I complained I received not very useful support and when I asked for reimbursement the customer service did not answer anymore.
Developer Response ,
hi Michael,
After we have explained you how to use the Breathe app and Watch you have not reached out to us anymore, hence we thought you had it under control. This is our last message: "Can you check that you have heart rate variability data under Health / Heart / Heart rate variability? If you have even just 1 data point for HRV in the past hour, and associated heart rate, then we will read it. If Apple doesn’t do their part, unfortunately there is little we can do, and what doesn't work reliable is not our app.
My guess is that sometimes data is of poor quality and the watch does not write it to Health, hence making it impossible for any app to use it. It’s really a pity that Apple provides no access to developers to their new ECG functionality, and not even to this optical measurement or the RR intervals, basically we are locked out and the only thing we can do is to recommend using the Breathe app as it should consistently push data to Health. When it doesn’t, as you can see there is no way to know why (signal quality or other issue being the cause).
I would recommend on those days in which after 1-2 tries the watch still does not work properly, simply to use the camera based measurement to avoid frustration. The measurement is validated and very accurate: https://www.researchgate.net/publication/315059917_Comparison_of_Heart_Rate_Variability_Recording_With_Smart_Phone_Photoplethysmographic_Polar_H7_Chest_Strap_and_Electrocardiogram_Methods - hence there is really no reason to use the watch instead of the camera, especially considering that with the camera we can also better detect signal quality and provide you with more HRV features and feedback.
Hope this helps"
Let us know via email in case you need more support or the refund, it's no problem, we are always here to help.
Useless
They idea would be so good but it's simply not working properly. Gave me readings of an 7.8-8.0 hrv three days now... Wasted my money on this
Developer Response ,
hi there, if you are looking for the rMSSD number, you can do so by enabling rMSSD under menu / settings / HRV View. Otherwise the number you see is a logarithmic transformation of rMSSD, as often reported in literature (and therefore lower). Please feel free to reach us at hello@HRV4Training.com should you have any other doubts. Thank you
