What is Live Sync?
Live Sync allows you to track the same workout on iPhone and Apple Watch at the same time.
Activity made on one device will be reflected on the other. In addition, Apple Watch will track your Heart Rate for the duration of the workout.
Live Sync does increase Apple Watch battery consumption due to the additional communication required between devices.
Please ensure that Workouts permissions are granted for Strong for improved performance and reliability.
You can enable Live Sync by going to Settings > Apple Watch after setting up Strong for Apple Watch.
