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
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, SportTracks, Genetrainer and Strava
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.).

ssalbo,
Cool idea, excellent metrics, terrible execution
The ability to measure with a Bluetooth HR strap has degraded significantly. Seriously, Healthnis recording my HR at 54bpm right now, and HRV4TRAINING is showing 154, 99,167, 44, 138, etc. at the end of the measurement “signal quality not optimal, please try again later”.
It all worked flawlessly until the developer started pushing their “pro” website. Now it is almost impossible to get an “optimal reading”. Given the significant investment in time you have to put in to get information out, the readings should not be impossibly finicky. I’ve compared performance to an Apple Watch, a Garmin Fenix, and Elite HRV app. None are as finicky in getting a good reading as HRV4TRAINING has become.

Beekaytab,
The best app out there for HRV!
What can I say I’m impressed. I’ve tested and downloaded several other HRV apps but they either required an external or didn’t support the new Apple Watch feature that supports HRV. Even though this app doesn’t support the Apple Watch either, it still offered the ability to use my existing iPhone. Don’t be fooled, the iPhone camera works just as great. I used to use the camera for other things to measure HR and I found it to be just as accurate. The HRV was spot on at least referencing against the Apple Watch readings.
As for the app, there are some bugs that I’ve worked with Marco to resolve so while minor he has worked with me. I do acknowledge that most of these HRV apps tend to favor runners, cyclists, or triathletes. Fitness and CrossFit folks are just as interested in peak training. Remember us too!
Lastly, the insights are great and this is the kind of easy advice I was looking for. Integration with other apps to include Strava and Training Peaks is a plus. A negative is the inability to get into the weeds with your data or edit but I just found out they have a Coach app that will allow you to do that and I might have to investigate that!
Overall very impressed and hope they keep developing this app.
As for the app, there are some bugs that I’ve worked with Marco to resolve so while minor he has worked with me. I do acknowledge that most of these HRV apps tend to favor runners, cyclists, or triathletes. Fitness and CrossFit folks are just as interested in peak training. Remember us too!
Lastly, the insights are great and this is the kind of easy advice I was looking for. Integration with other apps to include Strava and Training Peaks is a plus.

Disappointing $10
They sensor on the Apple watch has been proven to be accurate. (Yet no watch integration) A cardiologist actually laughed at the fact that this app uses a camera. We measured simple heart rate and found this app to be extremely off base. If it uses heart rate as a measurement in the hrv calculations, but it can’t accurately measure that, then how can they claim any accuracy at all?
I appreciate the response. Maybe it would be helpful to inform users before they buy the app that to get a true measurement, you need to have a Bluetooth monitor. Also I will add that I did not say anything about the health app measuring hrv. I just said that when i discusses it with my cardiologist, the cardiologist and I checked the heart rate before and after a stress test on my watch and then tried the hrv app with the camera. HRV4Training was very inaccurate. (If I can’t get an accurate bpm from your app (it was generally at least 20 bpm or more off while measuring with optimal connection) then how can it be trusted to measure R-R intervals?

Difficult to use, never seems to work
I have an Apple Watch and use both workouts and the Strava app. I’ve experimented with only using Strava to try and get this app to give any useful data, to no end. Giving up on it. Not user friendly, resulting in no useful data.
Point in case - the volume of responses to user complaints in the app reviews. They speak to the flawed app design. It shouldn’t require myriad personalized responses. If the app was clearly designed to communicate intent and method, it would be clear that you need additional equipment, that they’re unable to use the Apple Watch because of API restrictions, and that this requires readings to be done in a specific and consistent way (best I can piece together).
The frustration and research necessary to successfully use this tool are simply too high for many users. The developers seem to understand the science they’re working with, but not how to effectively communicate about it.

NYC Techie,
It’s not the training it’s the recovery that counts
I’m loving this app!! Deceivingly simple to use. Incredibly useful insights. To get this level of physiological insight for $10 bucks is simply AMAZING. The fact that it can all be done with the phone you already have is downright awesome. Hats off to the developers!!
Athletic improvement comes from stressing the body and then allowing the body to recover and adapt.
The whole point of training is to give the body the maximum amount of training stress it can recover from before the next workout. But how much is too much? Training and life stress can accumulate in quite unintuitive ways. Especially over time. That’s what this app helps you to understand and it does it with a direct measurement of your particular physiological “state”, and then tracks that over time.
I linked it to Strava and Training Peaks (super easy) to pull in workout data and now have a single point of reference for monitoring fatigue. Just great.
If you want to optimize your training time and efforts this is absolutely the app to get. Incredible value for the $$.

Amazing App for Monitoring Your Health and Stress
I am now a two year user of this app. Initially I used this app and two other HRV tracking apps, but have long since deleted the others and rely on this and Marco’s HRV Logger for HRV. I’ve used it with the camera, a Polar H10 strap and now in combination with an Oura ring. Always accurate results, but more importantly, solid training perspective on how ready I am to really push myself. The app seems to know my readiness to perform better than I sense it myself, which I find amazing. Only improvement I can think of is that it needs a category for athletes older than the “50 and older” for those of us very senior athletes. Best HRV app available.

Pillow HRV
This app requires an investment in time. And the ROI when using the camera as your sensor isn’t great since the measurements are not repeatable and are highly suspect.
Yes I’ve studied the blog post on using the camera. Back to back measurements under the same conditions result in a range 7.1 - 8.5. Heart rate is reasonably close to what Apple Watch reports.
App is good at manufacturing a signal from the noise. Too good. My pillow and bed sheets have scored 9.1, 9.5, and 12.3. Bpm tends to be way off at 2-3x actual and fluctuates wildly when I suspend phone above the bedding and the signal looks nothing like a heartbeat. Still, app reports good and optimal signal quality when camera is aimed at goldenrod colored sheets.

Indispensable training tool
I’ve been using HRV4Training daily for almost a year now to track my heart rate and many other aspects of my health, life, and training. The app has become an indispensable part of my training process.
HRV4Training is based on reviewed, validated research, and Marco uses his personal expertise and his experience as a serious runner to make the app focused and effective. His blog posts about the workings of the app and the science behind it are a tremendous resource. And he’s been unbelievably available in answering questions and helping me fine-tune my usage of the app.

Love/Hate Relationship
This app has changed my training for the better. I know I recover unusually quick but it’s hard to convince your coach without the data. This app has allowed me to train smarter and harder and on fewer rest days. The past two months, I’ve had a suggested take it easy day and it was spot on with how mentally and physically tired I was. However, the days when you get the ok to push hard is the best feeling. I love this app but it holds me accountable to really push or pull back when needed (hence the love/hate relationship).

A fantastic tool
This is an amazingly useful app for tracking your HRV. In particular, this app unlocks the ability to collect HRV for anyone with an iPhone. HRV is a fantastic biofeedback indicator that everyone should be tracking.
Especially now during the Corona Virus outbreak, I monitor my HRV daily for signs of immunity imbalance, as part of an advanced biofeedback monitoring and supplementation regime, so I can take steps to not get sick. Accounting for other variables that contribute to reduction in HRV, I’ve noticed I can get at least a 12-24 hr warning signal in advance of feeling symptoms.
The app does require some diligence taking your HRV readings and grabbing them from Apple Health. Apple doesn’t make it easy and clearly hasn’t figured out how important HRV is yet. But that’s not the developers fault.
I personally take readings using my Apple Watch, and do a 3 minute session with the breath app to get the HRV reading.
