Hi there


Please try this


If data permissions are disabled, the Apple Watch cannot log or sync sensor metrics to the Health app.


  • On your iPhone, open Settings > Privacy & Security > Health.
  • Tap Apple Watch and ensure all toggles—especially Cardio Fitness and Heart Rate—are turned on.
  • Go to Settings > Privacy & Security > Location Services > System Services, and make sure Motion Calibration & Distance is enabled.
  • In the iPhone Watch app, go to My Watch > Privacy > Motion & Fitness, and turn on both Fitness Tracking and Heart Rate.
