About HRV4Training

The only scientifically validated HRV app that doesn't require an external sensor. HRV4Training helps you optimize your goals by providing tailored feedback on your physical condition On compatibility with your phone: the app will detect right away if your phone is supported so that you can always get a refund in case it is not. HRV4Training in addition to our camera based measurements, supports the Oura ring, Coros watches and Bluetooth sensors (e.g. a Polar chest strap, our recommendation) 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 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. 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) - Configurable test (choose test duration between 1, 3 or 5 minutes) - Shows the PPG signal view to ensure signal quality during the test if the camera is used instead of a sensor - 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) - Population summaries and people like you comparisons to put your data into perspective - Data export via email - RR-intervals correction - Integrates with TrainingPeaks, Strava and others More details on HRV and app usage are available here: http://www.hrv4training.com/quickstart-guide.html and here: https://marcoaltini.substack.com/ 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.).

What HRV4Training Is Used For

HRV4Training appears to be a health and fitness app focused on heart rate variability tracking and training readiness. Based on the metadata, people commonly use it to measure HRV from a phone camera or with supported devices such as Bluetooth heart rate monitors, the Oura Ring, or compatible watches. It may be especially useful for runners and other athletes who want to check recovery, stress, and day-to-day condition before deciding how hard to train.

The app also seems designed for longer-term monitoring, not just single measurements. It includes trend tracking, training load analysis, and annotated tracking for factors like sleep, stress, travel, illness, and menstrual cycle. The permission set and sensor support suggest it is meant to connect with health devices, use the camera for readings, and store data for ongoing analysis on a phone. Based on the metadata, it is more of a personal performance and recovery tool than a general wellness app.
