Activity app. Not working

Hi

The following steps may help:

If you have not yet done so, update your iPhone and Apple Watch to the latest software, starting with your iPhone:

• Update the iOS software on your iPhone, iPad, or iPod touch - Apple Support
• Update the software on your Apple Watch - Apple Support

Check that you have fully 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).

• Your heart rate. What it means, and where on Apple Watch you’ll find it. - Apple Support
• Wrist Detection can be affected by temporary or permanent skin changes, such as by some wrist tattoos.

Check that your personal information remains accurate:

• On your iPhone, in the Watch app, go to: My Watch > Health > Edit - tap and adjust items, then tap on Done.

Restart both your iPhone and your Apple Watch, turning both off together, then restarting your iPhone first:

• Restart your iPhone, iPad, or iPod touch - Apple Support
• Restart your Apple Watch - Apple Support

Don’t know if this helps but I had to turn off “I’m Driving”

After my first use in a car, activity app stopped working

We was out walking as no matter how far we walking it didn’t register on my watch

Turned I’m Driving to manual and everything back to normal now
