United StatesThe 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, bluetooth and ANT sensors, supports the dedicated sensor present in Samsung Galaxy phones as well as the Oura ring.
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 (or 80/20)
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) or ANT+ heart rate monitors.
- 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)
- 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
- Data export via email or Dropbox
- RR-intervals correction
- Integrates with TrainingPeaks, SportTracks, Genetrainer, Strava and others

I was using it in iPhone when I switched to Android the developer was prompt to respond and resolve the issue for all my queries and resolve it. This app works great 😃
Not very user friendly and if you laready have Garmin Connect and TP you don't get anytjing new that you don't already get there
Worked well enough on note that had a special chip. Does not work on s24 ultra with camera. Support pointed to help files (which I read and tried to follow before reaching out) and then stopped responding.
Been using this fine on iPhone, worked great. Switched to android and it simply won't work. it doesn't find the 2 chest strap I tried even though they're paired to the phone and camera just says not optimal signal despite trying about 10 times
One of the few fitness/recovery tools that can be trusted, with many simply giving 'fluffy data' and graphs. Great integration with various leading fitness products. The more you use it, the better you begin to understand your body, how it recovers and and how it accumulates stress.
This is a really phenomenal app. I have not bought a polar strap to check if camera reading is as accurate but variations in readings match the expected values based on what's going on in my life. Easy to use and very insightful. Free version gives you so much info already to help you understand your readiness for the day and factors that affect HRV. Thank you!!
I really wanted this to work and to like it, but the daily measurements are tedious because I keep needing to repeat on the process. I don't know why but the app usually says my measurement signal is not optimal. I can't work out why, or what I'm doing differently to when it's good. I'm truth I'll probably give up using this, despite the strong recommendations from so many runners I trust on you tube, and just use the hrv measured by my Garmin watch. This feels like £10 wasted.
