Data recorded on Apple Watch will be synced with iPhone via iCloud. Since Apple Watch sends data to iCloud via iPhone, synchronization may be delayed depending on the communication between Apple Watch and iPhone and the communication status between iPhone and network.

• Make sure you're signed in with the same Apple ID between your Apple Watch and your iPhone / iPad.

• Make sure iCloud integration is turned on. ("Settings"> "(your Apple ID)"> "iCloud"> "(your app name)".If you turn iCloud integration back on, it may take some time to sync all your data. )

• Please check the free space of iCloud. If there is not enough free space, the data will not sync between the devices.

• If the above does not help, try uninstalling the app and then reinstalling it (skipping the initial setup in My Workout).
