Frequently Asked Questions
How do you deduplicate workouts when a user wears both an Apple Watch and a Garmin/Oura ring?
I implement overlapping time-window priority resolution rules (ranking devices by sensor modality and user-configured source priority) so calories, steps, and sleep sessions are never double-counted.
