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).

I would like to know if you plan to add a French translation in a future update. A French language option would make the app more accessible and easier to use for French-speaking users. Thank you for your work and for considering this suggestion. Best regards. **Developer response:** Merci beaucoup pour vos gentils mots ! Nous sommes ravis que l'application vous plaise. Nous n'avons pas encore décidé si nous proposerons des traductions, mais vos retours nous ont aidés à établir nos priorités, et si nous décidons d'avancer, le français sera l'une des toutes premières langues que nous ajouterons. Nous vous remercions sincèrement d'avoir pris le temps de partager cette suggestion, et nous en tiendrons compte dans nos prochaines mises à jour. ### 5/5 — crazy! 🤩 *2026-05-14* die app ist mittlerweile super gut. früher hat sie eigentlich nur durchschnitte angezeigt, aber jetzt gibt es so viele insights und verschiedene werte… da bleibt wirklich kein wunsch offen… 😍 **Developer response:** Vielen Dank für die positive Bewertung! ### 5/5 — A good (maybe obsessive) measure *2026-04-12* I am 81 and obsessed with staying healthy for another 10 years at least! It’s pretty clear that research coming about now is that we actually can get up to 8-10 months back for every year we age and those stats are getting better all the time. (See Ray Kurzweil for deeper data). One thing is clear, our heart is a major key to our health and having a measurement that lets us know how we are taking care of our heart is an excellent piece of data. I’m an engineer so I love data and these data from the HRV tracker are really helpful to assess how I am doing relative to my recent and long term history. I can’t recommend it enough. It’s worth knowing how we are doing so we can adjust! **Developer response:** Thank you so much for your review! ### 3/5 — Sehr hilfreich, aber nicht mit Abo! *2026-02-06* Ich rufe die Infos über die App mehrmals am Tag ab. Sehr gut dargestellt und auf der Watch gut nachvollziehbar. Mit der Atemübung in der Achtsamkeits-App wird nach einer Minute die hrv gemessen. Wer mal googelt was die hrv ist wird erstaunt sein. ABER ich bin heilfroh, dass ich die App 2021 einfach für 3,49€ kaufen konnte. Ich würde sie nicht abonnieren, denn man kann die Daten auch einfach in der Health App einsehen. Sehr schade, dass man jeden Mist heutzutage abonnieren soll. ### 1/5 — Menu?? Settings?? *2025-12-10, version 2.6* Is there a menu for the app? My goodness ### 5/5 — Great application to measure stress *2025-10-28* Hi there, it was pleasure to use HRV tracker. Developers are very responsive, kind and deep dive to issue. I had two watches and they found solution. Its really nice functionality about current stress level. **Developer response:** Thank you so much for your feedback. ### 1/5 — Tested *2025-10-11* Very infrequent HRV updates and a waste of £1.99 ### 1/5 — Does not work for new Apple Watch *2025-10-07* Hi there, it was pleasure to use HRV tracker on previous watch. But after last updates right now I can see only lock. Also, I’ve tried to play with subscription - it does not work. Ive contacted developer of the app, and from first time my email was ignored. When I follow-up again they have started diagnostics. Unfortunately after following several guidelines nothing happened. It was nice functionality about current stress level, but after adding reports and other unnecessary features application does not work anymore on my device. It’s sad **Developer response:** Thank you for your feedback. For some reason, your legacy paid app status isn't syncing from your iPhone to your new Apple Watch. Unfortunately, we haven't yet been able to determine why the sync fails on your device, while it works as expected on others. We're very sorry for the inconvenience, and we're doing our best to resolve this issue affecting your Apple Watch. ### 1/5 — 1980s app *2025-09-16* Don’t update when transferring to new iPhone. Unintuitive, incompatible and basic. fail. ### 2/5 — Removed complications features and now the app doesn’t pick up my HRV readings *2025-08-29* When I wake up I run a mindfulness meditation to capture my waking HRV. Then I open this app on my watch to see what the reading is. In the last couple months or so this app has changed the complication features to the point I had to completely change a watch face I had for a long time. Now suddenly I can’t even view my latest readings from the watch app? Getting buggy. May not continue using it. I’ve checked all permissions and my other apps are still able to read my HRV data. This app is losing its edge. **Developer response:** Sorry to hear that the complications aren't working as expected on your device. This issue probably occurs when the app tries to update from the old legacy version to the completely renewed 2.0 version. You probably need to reinstall the app on your Apple Watch and restart your device. If this doesn't work please contact us at contact@sydvesti and we will happily help you out with getting the app working again. So sorry for the inconvenience. ## Frequently asked questions about HRV Tracker for Watch ### What does HRV Tracker for Watch do?
