Apple Watch Series 12 help you better understand your body and daily activity. A redesigned health monitoring system with optical and electrical sensors, the S11 chip, and larger, energy-efficient green LEDs provides more information about heart activity and enables more frequent heart rate measurements.
The Readiness Score evaluates recent activity, vital signs, and sleep every morning and clearly shows how prepared you are for a demanding day or workout. The value is dynamically updated throughout the day, helping you better plan your energy and rest. Sleep tracking analyzes sleep duration and regularity, awakenings, and individual sleep stages, then provides an easy-to-understand overview of your night's rest in the morning.
The watch measures HRV, or heart rate variability, as often as every five minutes. This helps track the body's response to stress and recovery. For sports and everyday movement, it offers more accurate step counts, advanced workout metrics, and Workout Buddy. Health features such as cycle tracking and ECG are also available, along with safety tools including fall detection and contacting emergency services. You can make calls, send messages, and stream music with the watch even when you do not have your iPhone with you.
