Onboarding drawn only by light. A wind-down routine, a painted relax library, a breath player and a sound mixer. Bedtime, a dim tracking ring, a smart alarm window and a morning check-in. Then the report: score, stages, recovery, night sounds, trends, sleep debt, a coach that answers with your own nights. Hydration, caffeine, heart rate, stress, activity and biomarkers feed the same story. One person, one month, one night: every number on every screen agrees with every other number.
