The fact that there are sometimes minor discrepancies between the activity calories displayed in Samsung Health and Fddb is unfortunately not due to Fddb.
Upon request, the Samsung Health development team informed us that they make their own calculations for their display of daily burned activity calories from all activities and do not pass on this internal knowledge to third-party providers such as Fddb.
In response came from Samsung Health:
"We got reply from the developer group, that Samsung Health is calculating daily calories burned by merging all activities and exercises using its own policy. Unfortunately, this is internal knowledge and we cannot share it."
Unfortunately, we at Fddb cannot do anything further here and cannot offer a more precise solution for data import. This is equally frustrating for us and our users and we are very sorry. We ask for your understanding, thank you very much.
