Overview

  • A graphic labeled "Watch Focus Score" was found in the Health app code of iOS 26 beta, depicting an Apple Watch display showing an "84" encircled by colored stage indicators.
  • The segmented ring uses colors matching Apple’s sleep stage palette, hinting that the feature may merge time awake, REM and core sleep into a single score.
  • Surrounding icons—including a thermometer—point to possible integration of body temperature alongside sleep metrics, echoing the Vitals feature introduced in watchOS 11.
  • Apple has not confirmed the sleep score functionality or its release, and no further references have appeared in the current beta builds.
  • Competitors such as Fitbit, Oura Ring and Garmin already offer composite sleep scores, underscoring pressure on Apple to add an at-a-glance sleep quality index.
