Data consistency between Apple Health and Garmin

Hi everyone,

I use Apple Health as a hub to process all my health-related data (Strava for running, a Withings smart scale, movement data collected by my iPhone, etc.).

Since buying my Garmin Forerunner 265, I’ve noticed that the data recorded by my watch (and synced via the Garmin Connect app) is not correctly reflected in Apple Health.

This morning, I went for a run. My watch shows 10.11 km for 9,253 steps :

But when I check Apple Health, I get noticeably different numbers :

However, when I tap “Show All Data,” I can see that the total of all Garmin Connect entries does add up to the correct value :

I used steps as an example, but I’m seeing the same issue with distance as well.

Has anyone encountered a similar issue or knows how to fix it ?

Thanks,

Sébastien

If Apple Health receiving correct data from Garmin Connect I would say, problem is on Apple Health side and suggest address it to Apple support.

Thank you for getting back to me !

I’ve already reached out to Apple Support, but I was wondering if this could be related to the way the data is being interpreted, since I’ve never seen this happen before. I thought maybe someone else might have experienced the same issue.

I think I know where is the source of your problem.
In Garmin distance is taken from GPS readings during activity, in Apple Health distance is estimated from number of steps multiply by average step length.
I suggest what is step length set in your Apple Health and I think mystery will be solved.
