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.

App UI broken
2020-03-27

Was keen to visualize my HRV data so downloaded the app. Currently the iOS and Apple Watch app UI is broken. I only see a trending graph at the bottom but everything else is blank. The Apple Watch app only shows a single dial.

Sorry to hear that HRV Tracker is not working correctly on your devices. It sounds like your Apple Watch has not been able to record any HRV measurements recently. This is probably the reason why HRV Tracker is not showing additional data (the Apple Watch only keeps health data for about one week). Can you confirm this by opening the Health app on your iPhone. Then go to Browse > Heart > Heart Rate Variability. When was the latest HRV reading recorded? Can you also send us a screenshot of what you can see in the iPhone app. You can contact us at contact@sydvesti.com

Great concept, but doesn’t do enough readings and lacks certain features

I was really eager to try this app as I try to be more mindful of my mental health. However, the readings the app does are pretty inconsistent in term of delay between each one. Some days, I’ll get 3 readings before noon, and none in the afternoon. I wear my watch all the time, except before bed.Other than that, the app has a really clean and intuitive UI.It would be great to have a certain idea of what the readings mean, too. Like what’s a good HRV, and a bad one?

Thank you for your feedback. You can also manually "force" your Apple Watch to record new HRV readings by using the Breathe app on your Apple Watch. Just start a breathe session and a new HRV reading will pop up in HRV Tracker after the breathe session ends. So why the variation in delays: Depending on the series of your Apple Watch and how active you have been during the day your Apple Watch will record ~ 2-12 measurements. In order to be able to record your HRV the Apple Watch tries to detect time slots when you are not moving. As an example on an average office day my series 4 Apple Watch records 6-12 measurements, but during weekends when I am more active I will end up with a couple of morning and evening measurements.HRV is really personal so defining universal good and bad HRV readings would not work. But by following your personal HRV trends you might for example see that your daily HRV is declining because you are for example training or working too much. As a personal example my daily HRV average will start to drop and stay below my all-time HRV average if I do not get enough sleep. So by following your HRV trends and by comparing HRV to other health metrics you might start to see patterns how your personal HRV reacts to different situations

Waste of money. No insight or functionality beyond static graphs
