I don't think it does double count. I think it intelligently figure it all out.
It's supposed to do whatever one is in priority on the list.
If you open the Health app and tap on Steps and choose "Share Data", you will see a list under "DATA SOURCES:", then underneath the list it tells you "The sources above are allowed to update your Steps data. When multiple sources are available, one data source will be chosen based on the priority order listed above."
i thought it just adds them together somehow?
The main issue isn't the health app, it works it out smartly, I think the issue arises when using tracker apps, like life sum, which for some reason uses both measurements instead of just taking the total from Health, then you get real weird and funky cals burned and much higher activity than is really true.
I have the same issue in life sum!!! So annoying. I think it's not apple's fault but lifesum's.
I reported it too and they claimed they are aware of the issue and have already submitted a fix to apple, awaiting approval. Hope this gets fixed soon!
Would it be better to have the iPhone is top priority, and then the Watch? I believe I read that the Watch will struggle to count steps when you're doing things similar to pushing a shopping cart or stroller.I have the Watch as the top priority.
It just worries me - if my phone senses movement, then why isn't my Watch doing the same thing?
How though? If my iPhone thinks I'm moving, then my Watch will be on my wrist... so the Watch should be the only thing on this screen from the point I synced it with my iPhone, surely?
My phone and watch show the same exact step count. It's not double counting as I know what my average steps counts were before I got the watch just using the phone by itself.

Also, the iPhone has an altimeter to measure flights, whereas the Watch doesn't. Since waist-worn activity trackers are generally more accurate than wrist-worn ones, I wonder if the same would apple to the iPhone and Watch.
