Activity App

Hi

If Activity app data from your Apple Watch is not syncing to your iPhone as expected, then I suggest that you follow the instructions here, if necessary including unpairing and re-pairing your Apple Watch - including if either or both of your devices indicate that they are connected, but they do not behave accordingly:

• If your Apple Watch isn't connected or paired with your iPhone - Apple Support
• Unpair your Apple Watch and iPhone - Apple Support
• Set up your Apple Watch - Apple Support
