4. Readiness Score
The Readiness Score is a unique feature that tells you how prepared your body is for the day. It considers sleep quality, recovery, activity, and overall health metrics. This helps users decide whether to push hard in workouts or take it easy. Over time, the readiness score can highlight patterns and help prevent burnout or overtraining.
