Heart Rate Variability (HRV) measurements recorded by your Apple Watch can provide insight into the stress your body is experiencing. By using HRV Tracker to track short-term readings and long-term trends, you can see how factors such as daily workload, workouts, and sleep affect your body's readiness, recovery, and stress. Simply put, the higher your HRV, the better. ***Requires Apple Watch with watchOS 10 or later*** HRV Tracker for Watch integrates with the Health app and uses data stored in the Health app. To ensure your Apple Watch can record HRV measurements, open the Health app on your iPhone to check for existing data: Health app > Browse > Heart > Heart Rate Variability. In addition to automatic recordings, you can also use the Mindfulness app on your Apple Watch to capture new HRV data. Start a Breathe session, and once it ends, a new HRV measurement will appear in HRV Tracker. ***Compare HRV to Other Key Metrics*** Identify potential causes for changes in your HRV with Comparison Charts. -Compare your HRV to relevant health metrics such as activity, sleep, and resting heart rate. ***Follow Long-Term HRV Trends*** Track long-term HRV trends on your iPhone and compare short-term readings to your long-term averages. -Experience smarter insights with the new HRV Trend Summary feature (experimental). Available on Apple Intelligence powered devices running iOS 26. ***Get Notified on Your Apple Watch*** HRV Tracker helps you spot changes in your HRV by monitoring your data in the background and notifying you when your HRV falls below or rises above your preferred levels. -Tracks individual readings as well as 24-hour and 7-day averages. -You can customize the default notification thresholds in the Apple Watch app. -For notifications to work properly, add HRV Tracker to your Watch Face. -Note that notifications may be delayed due to factors like low battery. ***And More*** Track your HRV in multiple ways on your Apple Watch and iPhone. -Choose from various Home Screen widgets or Watch Face complications -Customize charts and views in settings -Scroll and tap on charts for additional insights ***Privacy*** Your privacy is really important to us — we do not collect any data from this app. ***How Is It Measured?*** HRV Tracker uses heart rate variability measurements calculated by detecting the variation between individual heartbeats. Your Apple Watch automatically measures HRV in the background and stores it in HealthKit. HealthKit uses SDNN (Standard Deviation of NN intervals), which reflects the standard deviation of time between normal heartbeats (measured in milliseconds). Please note that many of the features mentioned above are available only to subscribers.

Easy to use and clean interface

It’s a cool app, easy to use and interpret, clean interface. I’d give the app a 5 star and be a major advocate for it, if it had three key features. 1) consistent with how the Whoop device operates based on their extensive research on HRV and usage by professional athletes and coaches, I’d like to see the option to have the app use only one critical hrv value in place of a daily average of multiple readings, namely a reading taken during deep sleep at night. This could be a reading associated with the lowest heart rate at night while sleeping. The reason for this feature is that your hrv reading when you first wake up in the morning is most indicative of your physiological capacity to take on strain for the day. A daily average is not as informative because there are multiple factors during the day that can decrease or increase your hrv, which may not be indicative of your capacity to take on more strain. Alternatively the app could just use a reading immediately after you wake up and you are at resting heart rate. 2) allow the app to sync with TrainingPeaks, sending only only that single deep sleep or morning value. 3) provide some interpretation of the hrv trends. This will require the app to establish a baseline over time so that it knows what your lows and highs are, which in turn can offer coaching advice. For example a 50 may be a high value for an untrained non athlete but low for an athlete who can get values above 100 consistently. Hrv is meaningless to the average person without some analysis relative to their fitness level, baseline data etc. It’s just a bunch of numbers. So, I got an hrv value of 32 today. So what? Should I run that 20k or not? Should I take the day off or do more active recovery?

So far so good!

I have an Apple 4 watch. I wanted to know my Heart rate variability and this does that. It’s pretty basic but is easy to use. I also added it to my watch face and you don’t have to use the breath function for it to work. I almost bought a whoop because I wanted the info quicker. The recommendations I would make are to have the info come up in a score form based on sleep, HRV and workouts or other things. I am a coach for CrossFit and this is something we can use. I look forward to the update and would love to help if you guys needed some info. Thanks

I got this app because I did not want to spend the big bucks on WHOOP. I have been exercising regularly for the last year and half (5-6 days week) and have stopped making progress and felt I may be overdoing it. Since getting this app My scores are always low unless I used Breathe app on Apple Watch, then my numbers skyrocket. I have taken 4 days off and numbers still low. Perhaps I need more rest....The developers of this app have been quick to respondto my questions, which I appreciate.

I use HRV for training and recovery. This app did exactly what I needed. I have a professional background in USA Cycling, USA Track and Field, USA Swimming, USA Triathlon, ACE Personal Training, college anatomy and physiology, and Emergency Medicine. All occupations are starting to see an emergence of HRV as a significant training/medical tool. After working my way through several other applications, this one did what I needed for predicting immediate changes without any frustration. Worth the purchase. I look forward to seeing how the app develops.I’d love to offer insight based on my knowledge, experience, and needs.
