Sleep Tracking

Status: Current implemented behavior. Audience: Users and contributors. Implementation: features/sleep, data/repository/SleepRepository.kt. Navigation: Screen.Sleep, Screen.SleepDetail, widget SLEEP. Related: Feature map, Sleep score and recovery, Statistics.

The sleep feature owns the main period-based sleep detail screen and individual sleep-session detail route.

What It Shows

Sleep can show:

  • Sleep sessions for the selected period.
  • Day summaries and period summaries.
  • Sleep stage timelines where Health Connect stage data is available.
  • Duration, efficiency, score, continuity, goal progress, and recovery context.
  • Session lists and session details.
  • Previous-period comparisons, baselines, confidence, and source labels.

Detail Pattern

Sleep follows the canonical period-detail model:

  • Day, week, month, and year ranges.
  • Selected anchor date.
  • Previous/next navigation and calendar selection.
  • Pull to refresh.
  • Day-specific content when a daily summary is available.
  • Week/month/year content when sessions exist in the selected period.
  • Reorderable sections.

The sleep session detail route is separate from the period overview and focuses on one session’s timing, stages, and source context.
