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

1

Open integrations

From Settings, open Apple Health.
2

Review the explanation

Read which data IronLedger requests and why. Continue to the system permission sheet.
3

Choose permissions

Enable the categories you want to share. Apple controls the permission interface.
4

Sync completed workouts

Enable Auto-sync workouts to write eligible sessions after completion. Use Sync Now to process completed workouts from the last 30 days.

Energy estimates

IronLedger estimates strength-training energy with: 3.5 MET × body weight in kilograms × workout duration in hours It reads a permitted recent body-weight sample when available, otherwise uses the cached weight or a 75 kg fallback. The result is an estimate, not a direct measurement of calories burned.
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.
Apple Health is unavailable in the iOS simulator. Test the connection on a physical device.

Sync and deletion limits

  • Apple Health is available only on supported iOS devices.
  • A workout must have an end time before it can sync.
  • IronLedger avoids writing the same eligible workout twice.
  • The app cannot delete HealthKit workouts after writing them. To remove one, open the Health app, go to Browse → Activity → Workouts, find the IronLedger entry, and delete it there.
The green sync-status indicators show the connection state. Apple does not allow an app to query every Health write permission reliably, so manage individual permissions in the Health app.
