Get better results

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

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

  • Learn how to update your personal information.

  • See your Activity history.

  • Learn more about the Workout app.

  • Learn 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.
