Your Body Battery

Four scores. One clear picture of how you feel.
Apple Health stores the raw data; it doesn’t spell out what it means for today. Your Body Battery does — four answers you can actually use.

The app reads the same information already in Apple Health and distills it into real-time energy, sleep quality, stress, and daily strain: what matters for planning your day, with charts, trends, and optional nudges. No extra accounts — everything stays on your device.
