Get better results
- Your Apple Watch estimates your measurements during workouts based on the information that you entered during the setup process. Here's how each workout is measured:
- Pool Swim: when you start a workout, make sure you accurately set the pool length 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.
