Hi
Activity data, including steps, is synced automatically to the Activity app and Health app on your iPhone when your devices are connected.
If your activity is not currently being tracked or synced by the Activity app, then the following steps may help:
Check that the software on your Apple Watch is up to date:
Check that you have set up the Activity app on your watch:
- When viewing the time on your watch face, tap on the Activity rings icon / complication, or;
- Go the Home screen (via a single press of the Digital Crown) and tap on the Activity app icon (coloured rings).
- To get started, you will need to enter some personal information.
Check that Wrist Detection is turned on and that, if passcode is enabled, you are unlocking your watch after placing it on your wrist
- On your iPhone, in the Watch app, go to: My Watch (tab) > General > Wrist Detection - turn on.
On your iPhone, go to: Settings > Privacy > Motion & Fitness - check that both Fitness Tracking and Health are enabled.
On your iPhone, in the Watch app, go to: My Watch > Privacy > Motion & Fitness - turn on Fitness Tracking and Heart Rate.
Check that you are wearing your watch sufficiently snugly on the top of your wrist (if it is worn too loosely, your watch may believe that it has been removed from your wrist).
Check that your personal information is accurate:
- On your iPhone, in the Watch app, go to: My Watch > Health > Edit - tap and adjust items, then tap on Done.
Calibrating your watch improves the accuracy of various activity-related estimations. Instructions for how to calibrate your watch are available via the support article linked below.
