History

Use Heart Graph on your Apple Watch to view the heart rate data the watch acquires in the background all the time while you’re wearing it. The History page will always show you the most recent data, and the duration can be configured (from 1h to 12h) in the iOS app.
Watch_History

You can import the history data displayed to Heart Graph on your iPhone for further analysis such as comparison with previously acquired data by scrolling down using the digital crown.

Workouts

Recording your heart rate during workouts with Heart Graph on your Apple Watch allows you to see how much time you’re spending in each of your heart rate zones with the Zones page.

Watch_Zones

Of course, you can also see a graph of the last few minutes of your heart rate in the Workout page, for example to allow you to see how your heart rate is recovering after a burst of activity.

Watch_Graph

During your workout you can use the Summary page to see basic stats such as mean and maximum heart rate, and the number of calories burned. Heart Graph offers a large list of workout types so that you can choose the best fit for what you’re doing (see the Other option when starting a new workout). You can also record resting heart rate, which can later be compared to other workout statistics in the iOS app.

Watch_Summary

A workout can be stopped at any point by pressing firmly on the screen and selecting the Stop button. Data will then be transferred to the iOS app, where it can be reviewed, compared to other sessions and analysed.

Resting heart rate

When starting a new session, you can select “Resting” to record the minimum heart rate attained during the session using the Apple Watch’s high-frequency heart rate sampling. This minimum value can then be compared to heart rate from other sessions using the statistics comparison feature of the iOS app.

Requirements

To run Heart Graph, you need at least WatchOS 4.0 on your Apple Watch.
