Common Questions & Fixes

Health access is missing or incomplete

  • Open iOS Settings > Privacy & Security > Health > Zone Trainer
  • Enable all requested read permissions (workouts, heart rate, routes, effort)
  • Return to the app and refresh Timeline

No workouts are showing

  • Make sure workouts exist in Apple Health/Fitness
  • Pull down or wait a moment for sync to complete
  • If it still doesn't load, try closing and reopening the app

Older history is locked

Zones look wrong or need changes

  • Go to Settings > Zones
  • Edit zone ranges/colors or use the Setup Wizard
  • Tap "Recalculate Workouts" after changes

Effort score is missing

  • Effort scores sync only on iOS 18+
  • You can still add/edit effort in the app; older iOS versions keep it local

Manual workout entry

  • Heart-rate data will link automatically if it exists in Health

Tags or activity colors aren't syncing

  • Go to Settings > Tags or Activity Colors and make a small edit
  • This triggers a refresh and iCloud sync

Delete a workout

  • If the workout was recorded by Zone Trainer, you can delete it inside the app
  • If it came from another app, delete it in Apple Fitness/Health

Subscription restore

iCloud reset (advanced)

  • Settings > Advanced > Reset iCloud Data
  • This rebuilds iCloud data from HealthKit and restores titles/notes/tags

Privacy & Data
