Apple Watch activities ring not work

Hi

The following steps may help:

Check that you have set up the Activity app:

• Track daily activity

Check your personal information, which is used when your Apple Watch estimates Activity results:

• On your iPhone, in the Watch app, to go: My Watch > Health.
• Check and, if required, edit your data to ensure that it is accurate.
• If the setting for Wheelchair currently states "Not Set", then tap on Edit (upper-right) > tap on "Not Set" and change it to "Yes" or "No" as appropriate (options are shown in the bottom area of the screen) > tap on Done (upper-right).

If you are not yet doing so, then use these settings and check that you are unlocking your Apple Watch after putting it on:

• On your iPhone, in the Watch app, go to: My Watch > Passcode:
  • Turn on each of Wrist Detection, Passcode and Unlock with iPhone.
• After putting it on your wrist, your Apple Watch will then unlock after whatever you do first: either unlocking your watch manually (by entering the passcode) or unlocking your iPhone.
• It will then remain unlocked (including when the screen is asleep) until you remove it from your wrist.
• When you remove your Apple Watch, it will lock automatically.

Check that you are wearing your Apple Watch sufficiently snugly on the top of your wrist (it may otherwise believe that it has been removed):

• Wearing your Apple Watch - Apple Support

Other issues that can impact sensor performance include skin perfusion and wrist tattoos:

• Your heart rate. What it means, and where on Apple Watch you’ll find it. - Apple Support
• Get the most accurate measurements using your Apple Watch - Apple Support

If you have ever (not necessarily recently) previously used the Workout app and/or any third-party fitness, sleep or heart rate tracking apps on your watch, then check on your Apple Watch to see whether there is an active or paused activity within any of them.

• If there is, end that activity from within the app on your watch (not your iPhone).

• If in doubt, remove any such third-party apps from your Apple Watch.

If you are using any third-party fitness tracking apps, then check the developers' support resources and/or contact the developers to check for any known issues affecting how data is shared to the Health app on your iPhone.

Follow this sequence of steps:

• Turn both devices off together, then restart your iPhone first:
  • Restart your iPhone, iPad, or iPod touch - Apple Support
  • Restart your Apple Watch - Apple Support

Unpair and re-pair your Apple Watch:

• The Watch app on your iPhone takes a backup of your watch automatically when unpairing via the app.
• Initially choose to Restore from Backup during set up (most data and settings will be restored, with some exceptions, such as Apple Pay cards, passcode).
• If the issue persists, consider instead unpairing and setting it up as a new watch.
• Unpair your Apple Watch and iPhone - Apple Support
• Set up your Apple Watch - Apple Support

If the issue then persists, I suggest that you contact Apple Support (remote diagnostics and/or mail-in service may be available, if required), make a Genius Bar reservation or visit an Apple Authorised Service Provider for assistance:

• US: Apple Watch Service Answer Center - Apple Support
• Elsewhere: Apple - Support

I had a similar problem that started two weeks after getting the watch in that the move ring at the end of the day showed maybe 50cal burned rather then the 500-600 normally.

Unpairing/repairing didn’t do the trick, resetting to factory did but lost all past data cause importing it from backup also brought the problem back, in the end the watch was fine for a couple of weeks and then it happened again.

Finally traced it to the iHealth scale that is connected by Bluetooth and on to the Activity app.

Well the problem is the dog, not that he isn’t a good dog, it’s that he sometimes like to weigh himself and my phone thinks I now weigh 17kg. Well a 17kg adult apparently burns about 4cal an hour, who knew. Solution don’t get rid of the dog, just step on the scale to reset and away you go.

This is an example of a day tracked with the weight of a small dog in place of an adult male.exercise is tracked but the minimal burn of calories and gaps in the activity bar chart are a result of the calculations being made using the wrong weight. I’m imagining that many problems will come down to improper data entered initially or modified through some unexpected input from some other source other than the watch.
