  • Your Apple Watch estimates your measurements during workouts based on the information you entered during the setup process. Here's how each workout is measured:

    • Pool Swim: When you start a workout, make sure you set the pool length accurately to help your Apple Watch measure laps and distance. GPS isn't used during a Pool Swim, and water may prevent a heart rate measurement, but calories, laps and distance will still be tracked using the built-in accelerometer.

    • Open Water Swim: GPS will only provide distance when you do a freestyle stroke. Water may prevent a heart rate measurement, but calories will still be tracked using the built-in accelerometer.

  • Find out how to update your personal information.

  • See your Activity history.

  • Find out about each workout type on your Apple Watch.

1. If your Apple Watch has watchOS 8 or earlier, rotate the Digital Crown instead of pressing it.

2. In earlier versions of watchOS, your rest time was subtracted from your splits. In the latest version of watchOS, your splits include your rest time.
