Why can step timing look different in Apple Health?

Apple Health can show a different hour-by-hour timeline when the connected source only provides a daily total.

Some step data from the connected source is only available as a value for the whole day. That means SyncFlow can know how many steps were recorded for a day, but not the exact hour when each step happened.

Because of that, Apple Health may not show the same timeline you see in the source app. This does not automatically mean sync failed.
