Apple Fitness Companion implements training, basic records, HealthKit, Watch, compatible walking schedules, twelve movement RealityViews, and lock-screen Live Activities. Native entry to complete lesson bodies, the full Chinese and English experience, and more complete-version features still need closure. Technical and runtime acceptance follow actual evidence. Technical integration does not prove real-user fitness outcomes.
