# Apple Health

> Connect IronLedger to Apple Health and understand workout and energy sync.

On supported Apple devices, IronLedger can write completed strength workouts to Apple Health and
use permitted body-weight data when estimating workout energy.

## Connect Apple Health

<Steps>
  <Step title="Open integrations">From Settings, open **Apple Health**.</Step>

  <Step title="Review the explanation">
    Read which data IronLedger requests and why. Continue to the system permission sheet.
  </Step>

  <Step title="Choose permissions">
    Enable the categories you want to share. Apple controls the permission interface.
  </Step>

  <Step title="Sync completed workouts">
    Finish a workout in IronLedger. Use the recent-workout sync option when you need to process
    eligible past sessions.
  </Step>
</Steps>

## Energy estimates

IronLedger estimates strength-training energy using workout duration and body weight. The value is
an estimate, not a direct measurement of calories burned.

<Info>
  Apple does not let apps reliably display whether every Health write permission is currently
  enabled. Manage individual permissions in the Health app or iOS Settings.
</Info>

Apple Health is unavailable in the iOS simulator. Test the connection on a physical device.
