BodyState transforms your Apple Watch data into a battery for body and mind. It helps you tailor your lifestyle, habits, and training programs to unlock your potential. At its core, BodyState uses four metrics to compute a score from 1 to 100, representing your body's state. A score closer to 100 means you are rested and ready to tackle what life brings.

The four metrics are crucial. They are sleep, fatigue, heart rate variability, and resting heart rate. These metrics significantly impact your health. They are measured against your personal baselines to understand your current energy level.

You recharge your battery while you sleep. When awake, it depletes. Activity level and sleep pressure affect the depletion rate. High activity drains the battery, while sleep pressure builds as you stay awake.

BodyState is a rhythm. It guides you through understanding your body's needs. It helps you maintain balance. It ensures you are ready, rested, and resilient. With BodyState, you can keep your body and mind in harmony.
