Apple Watch Series 12 provides an overview of important health and fitness data directly on your wrist. The redesigned system of optical and electrical sensors, together with the S11 chip, enables more frequent heart rate measurements. Improved main sensors and larger, energy-efficient green LEDs provide more data about heart activity.
The readiness summary evaluates recent activity, vital signs, and sleep every day into a single clear score that changes dynamically throughout the day. This makes it easier to determine whether it is a good time for an intense workout or, conversely, for rest. The watch also tracks steps, provides advanced workout metrics, and supports the Workout Buddy feature for even better motivation during activity.
Detailed sleep tracking analyzes sleep duration, sleep and wake-up regularity, and individual sleep stages, displaying an easy-to-understand sleep score in the morning. Apple Watch Series 12 also tracks HRV, or heart rate variability, which can indicate how the body responds to stress and recovery. Features such as ECG and cycle tracking are also available.
The watch lets you make calls, send messages, and stream music. For greater peace of mind, it offers safety features including fall detection and the ability to contact emergency services, even without an iPhone nearby.
