In iOS, segmented controls provide a horizontal set of mutually exclusive options that switch between different views of the same content. Unlike traditional tabs, these controls are designed for filtering or changing views within the same context, not for navigating to different app sections.

The Health app demonstrates this pattern effectively in its activity tracking views. When viewing daily steps, the segmented control offers views like "Day," "Week," "Month," and "Year" — different presentations of the same step data. Users can switch between these views to analyze their walking patterns over different time periods while staying within the steps-tracking context.

Similarly, heart rate monitoring in the Health app uses segmented controls to switch between views showing "Latest Reading," "Daily Average," and "Heart Rate Variability." These segments represent different aspects of the same heart rate data rather than navigating to unrelated health metrics.
