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 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.).
Fail
I’ve used this app for years and it continues to decline. At the last update it stopped syncing to Aura ring, and now it refuses to sync to Apple health also. I’ve emailed and they offer useful assistance. Time to change to a different app.
United StatesFunctional to the Max
I’ve been taking HRV since 2013 and moving to HRV4Training when it first came out. It does what it’s designed to do and does it well.
United StatesNot what I was expecting
I wanted this app to sync the raw HRV data read from Oura into TrainingPeaks. It doesn’t actually send the raw HRV number instead it’s sending a score which is not HRV.
United StatesAlmost Perfect
I use this app to record my resting heart rate and HRV every morning, and it's been reliable over the years. However, a few minor bugs stop me from giving it a 5-star rating. Fortunately, they don't affect the accuracy of the readings. I'll up my rating when these issues are fixed: 1) Vibration setting only vibrates at the end of a reading, not at the start. 2) Runs in fullscreen mode, hiding status bar items like time, battery, and Dynamic Island activity. 3) Start and end sleep time controls don't respect the device's time format setting (24-hour vs. AM/PM).
United StatesUsed to be amazing
I had been using this for three years successfully. For more than a month, the app says it has my OuraRing data but there is no display. Reached out to support and no reply. Is this app still supported? Disappointed because as an athlete, this is one of the only HRV apps that didn’t tell me that I was pushing myself too hard every day rather than most that are for general fitness.
United StatesGreat app
Very useful!
United StatesDown hill
Used this app for a while and started to go downhill. Kept having to log in every time and now it crashes after uninstalling and redownloading.
