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
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
- 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, SportTracks, Genetrainer and Strava

Ratings and Reviews
Simple to use, complex data made easy
This app is absolutely excellent. Simple to use each morning with Apple Watch or just your finger on the camera. Gives all the information you require to make your training and rest plan the best possible for your individual needs. Even better is that it gives this information without any weird proprietary algorithms messing with your data.
Information is pretty useless out of sync with reality if not just plain wrong. Obviously I am an outlier on the charts as HRV changes do not in any way align to actual real life feelings. HRV goes up after an intense strength session, telling me I can go intense when I can barely summon the energy to use the app, and telling me to back off when I am good to go after a rest day. Additional trends and analysis is really truly useless, no value in that analysis at all and the links to the website provide no useful information. I can’t believe I have wasted time and money on this pseudoscience hocus pocus. This isn’t science, this is rubbish stats unsupported by quality scientific analysis.
An app i can trust
HRV4Training is a scientifically valid, highly accurate fitness, health and heart data app that ticks all my boxes. The app dev’s - Marco and Alessandra - are highly qualified, committed, proactive and professional. HRV4Training quickly gathers all your metrics and produces relevant, easily understood raw and correlated information, helping both athletes and those managing fatiguing conditions. The app is adaptive, improving as you log more data, and packs a deceptively immense amount of useful information. It’s the only HRV app I trust.
