The same code for fetching HKCorrelation (Blood Pressure) on iPhone returns all records, but on watch just 4. Is there a documentation explaining such behavior?
It looks like only records added after installing the app on watch are synced.

Yes many articles and you can find it on apple document also, https://medium.com/@gorillalogic/apple-watch-healthkit-developer-tutorial-how-to-build-a-workout-app-de156733dd6a – Anjali Shah Mar 30 '20 at 06:20

Sorry, I don't see a clue nor documentation. It only says "Apple Watch have their own data, and iOS is the one in charge of synchronizing that data." without any details. – Szymon Klimaszewski Mar 30 '20 at 06:29

Lynda is not free, so I cannot check that link and link to Apple documentation is not answering my question. That's just quantity type doc. – Szymon Klimaszewski Mar 30 '20 at 06:50

What you want same app i found on app store also so it's possible. You must have to read all documentation properly. I also read and update you. – Anjali Shah Mar 30 '20 at 07:00

Still, I couldn’t find any specific info nowhere. Also similar apps shows last 3 records, or present some data from HK statistics query. Do I can just guess how it works, but I was wondering if that’s explicitly documented somewhere. – Szymon Klimaszewski Mar 30 '20 at 07:06

The issue was that on iPhone HKHealthStore returns all records, however on watch only records added by release versions of the app are fetched. That's why I didn't see the same data on watch as on iPhone.
