Description

Heart Rate Variability measurements recorded by your Apple Watch can give you insight on the stress level your body is under. By using HRV Tracker to track short-term measurements and long-term trends, you can see how your workload during the day, workout sessions or sleeping etc affect your body's readiness, recovery and stress level. Simply put, the higher your HRV is, the better.

***Requires an HRV capable Apple Watch with watchOS 6 or later***
To make sure your Apple Watch is capable of recording HRV measurements, please open the Health app on your iPhone to see if any HRV measurements exists. Go to > Health app > Browse > Heart > Hear Rate Variability. HRV measurements are not available with devices bought from China mainland, Malaysia and South Africa.

***Get Notified***
HRV Tracker makes spotting drops in your HRV easy by monitoring your HRV measurements in the background and showing notifications after your HRV drops under your desired level. HRV Tracker will monitor drops in individual measurements and also your 24 hour HRV average. You can change the default notification levels directly in your Apple Watch app. Please note that notifications can get postponed for example because of a low battery level.

***Apple Watch for daily tracking***
Browse through last seven days of HRV measurements by using the digital crown. See how measurements compare to your seven day period and individual days. By tapping the graph you can toggle through the first values of each day. Use complications on your Apple Watch to stay informed on changes in your HRV. 

Besides the automatically recorded HRV measurements you can use the Breathe app on your Apple Watch to record new HRV measurements. Start a Breathe session in the Breathe app and after the session ends a new HRV measurement will be available in HRV Tracker.

***Compare HRV to other key metrics***
Find possible causes for changes in HRV by using the comparison graphs available on your Apple Watch:
-Sleep hours: By default HRV Tracker will use sleep data provided by sleep apps that add sleep data to HealthKit. If no sleep data is available HRV Tracker will calculate estimated sleep hours per night (estimated sleep time will only be available in the Apple Watch app)
-Activity: By default HRV Tracker will use your Active Energy (calories) as the activity metric. In the HRV Tracker Apple Watch app you can choose to use a custom activity score that emphasizes the intensity of daily activity.
-Daily resting heart rate (RHR).
Toggle between comparison graphs by tapping the upper part of the screen.

***Follow Long-term HRV trend***
Follow your long-term HRV trend on your iPhone and compare your short term measurements to all-time data.
-Select week from weekly graph to see daily HRV values of the selected week.
-Browse through all daily HRV values of the selected day
-Compare daily HRV averages to other relevant daily metrics: Activity, Sleep (if available in the Health app) and Resting Heart Rate

***Today Widget on iPhone***

***Privacy***
Data read from the Apple HealthKit database is only used to show information related to your Heart Rate Variability. Information read by HRV Tracker is only stored and used locally on your iPhone and Apple Watch.

***How is it measured***
Heart rate variability measurements used by HRV Tracker are calculated by measuring the variation between individual heartbeats. Your Apple Watch automatically measures your HRV in the background and stores the outcome into HealthKit. HealthKit uses SDNN heart rate variability, which is calculated using the standard deviation of the inter-beat (RR) intervals between normal heartbeats (measured in milliseconds). Besides background measurements generated automatically by your Apple Watch you can use the Breathe app on your Apple Watch to generate new measurements.

Excellent customer service

I wrote a review a couple of days ago and stated that this app did nothing on either my phone or my Series 5 Apple Watch. My rating was 1 star. I am hoping that I have managed to delete this negative review as the problem is not the app but the country that I live in. Certain countries including Malaysia DO NOT support HRV tracking hence I believe it is disabled on Apple Watch. And so, my 4 stars are for the prompt, professional and courteous email exchange with the developer.
31/05/20 - Update. Noticed today that my Apple Watch is now showing HRV measurements since 12/05/20. And so, this app does now work as described. Thanks.

Developer Response ,

Thank you for your updated feedback and status update. Great to heart that now your device bought from Malaysia has also started to record HRV measurements. We will happily help you if you need any help with the app. You can contact us at contact@sydvesti.com

Heart rate variability tracker

This app only works with series 3 watches and above, this info is buried in the fine print. Do not buy until you can verify it works for your watch, as well as your phone. Bit of a rip off.

Developer Response ,

You are absolutely right that the device requirement was poorly described. It has not been intentional and we have now added the device requirement in the upper part of the of the App Store description. Unlike with iOS apps and iPhones there is unfortunately no way to block users from downloading HRV Tracker with older watchOS versions. This will hopefully change with the upcoming Apple Watch specific App Store. Again we are really sorry that the device requirement was poorly communicated by us. If you have a device capable of running watchOS 5.2 then please contact us at contact@sydvesti.com and we will help you with getting HRV Tracker running on your device.

Can’t click the ‘?’ At the top of the app

I can’t click the ‘?’ Icon at the top of the app because I have an iPhone X and the icon is under my battery and WiFi icons.
