Apple Watch Features
The Apple Watch offers a variety of features that allows the users to engage with the watch in their everyday lives.
Fitness Tracking
The Apple watch offers fitness tracking in the form of Activity Rings which is broken down into three colored rings. The first is the red Move ring which allows users to track how many calories they have burned by moving throughout a 24 hour period. The second is the green Exercise ring that allows users to track the minutes of brisk activity they have completed that day. Finally, the blueStand ring allows users to track how many hours they have stood in a 24 hour period. [2] The user can define their activity goals for each type of ring, and the ring visually closes once the user achieves that goal.
The visualization shown above demonstrates the different types of rings, as well as the users progress in completing the goals associated with each ring.

Ethical Considerations
Atrial Fibrillation
Atrial fibrillation is a common persistent arrhythmia and is associated with increased mortality and morbidity such as stroke. There is currently no evidence that screening for atrial fibrillation with smartwatches improves the outcome and reduces the number of adverse events. [2]
