Smart Watches are used for following purposes mainly:
1) A wearable device that’s designed to help you communicate, answer phone calls and deliver notifications.
2) A wearable that keeps track of your exercise, heart rate and sleep.
A smartwatch makes it easy to view and respond to emails, texts, calls and social media notifications on your wrist. Fitness trackers focus on health and activity monitoring, such as how many steps you’ve taken, the distance covered, the calories you’ve burned, and what your heart rate is.
