Swim.com tracks and captures heart rate data*. You can view this data on the iOS or Android application on your mobile device.
1. Select a swim and click on "View swimming details" at the bottom of the screen.
2. Select "HR" from the list in the top header menu - it is the last option in the list (far right).
3. Swipe the screen to the left to see the average, maximum and minimum heart rate for each interval of your workout.
Please note the coloring of the menu and headers are very difficult to read. We are aware of this and will be fixing it soon. We will also be adding heart rate data to the web version of Swim.com.
*Garmin wrist-based heart rate devices will not track HR data in a lap swim profile. Garmin disables the wrist-based optical hardware during lap swims and requires the use of the HRM-Tri or HRM-Swim chest strap to record heart rate data during a swim.
