In order for the ControlMyWeight iOS app to sync data across iOS devices (iPhone to iPad), each device must have the latest version installed, and be signed in to the same account. To determine if each device is signed in to the same account, open the app on each device and go to Settings > Account. If necessary, log out, then log in again using the same sign in details.
Recorded data also syncs between the ControlMyWeight iOS app and the ControlMyWeight web diary (https://program.calorieking.com), when signed in to the same account.
The ControlMyWeight iOS app, and the ControlMyWeight web diary, do not sync with CalorieKing Program or CalorieKing Australia online membership.
