Turn your Apple Watch into a powerful tool for tracking your heart rate zones while working out.

When working out with the Apple Watch you’ll want to work out within a specific zone, ensuring that your heart rate falls within a particular percentage of your heart rate.

Use Heart Rate Zone Training to ensure you get the most out of your workouts by tracking your heart rate zones.

Working close with Apple's own Health app ensures that all your training and workout data is safely stored and accessible in a secure way.

Heart Rate Zone Training will work without your iPhone on WatchOS 2!
