HardsetQuestions or a problem? Email me@nuc.gr. Include your app version, iOS version and what happened. Please do not send health records or training exports unless you choose to share them for a specific support request.
Three saved workout plans are free. One non-consumable purchase unlocks unlimited plans. Use Restore purchase with the Apple ID that bought the unlock. If the App Store is unavailable, existing plans and history stay usable. A purchase does not back up your training files.
Export a JSON backup from Settings; include history if needed. Import updates matching plans and adds new plans within your limit. If a file cannot be read, saving is paused: open Settings to export the unreadable file or recover the previous local backup. Recovery restores the previous snapshot, which may omit the latest changes. Delete all local data removes local training and backups after confirmation; it does not delete Apple Health workouts or copies shared elsewhere.
Health is optional. Change permissions in Apple's Health privacy settings. The Watch saves measured workouts after about one minute without a phone Save or Discard decision. Delete unwanted workouts in Apple Health.
