Related signals share one frame.
Workouts can sit beside sleep and recovery context; nutrition can sit beside activity and goals. Metric keeps each measurement distinct while making the surrounding pattern easier to inspect.
Apple Health, made readable
Metric is an Apple Health dashboard that organizes the data you choose to share—such as workouts, sleep, heart rate, HRV, VO₂ max, activity, body composition, nutrition, and blood pressure—into one clear view with trends and explanations. You stay in control of which Health categories Metric can access.

The useful answer
Apple Health is the system of record. Metric is the interpretation layer: it groups signals by the decisions they can support, keeps related trends close together, and gives every headline a path back to its underlying data.
Instead of checking separate screens for activity, sleep, cardiovascular fitness, body composition, and nutrition, you can start with one briefing and drill down only when something changes.

Inside Metric
Every summary should lead back to the signal, date range, or source that shaped it.

Keep the evidence
Move from a home tile to its charts, date ranges, and samples. A dashboard should shorten the path to understanding, not hide where a number came from.
Ask in plain language
Ask about a trend in the data available to Metric, then use the linked metric views to check the context yourself.
How it works
Select the Apple Health categories you want Metric to read. You can change those permissions later in iOS.
Metric organizes available history and updates views as new samples arrive from approved sources.
Start with the dashboard, open a metric, compare time windows, or ask Cortex a focused question.

Common questions
No. Apple Health remains the central store and permission surface. Metric adds a focused dashboard, trend views, and explanations for the categories you choose to share.
Not for every view. Metric can use compatible data already present in Apple Health, but Watch-based features need the relevant Watch samples and permissions.
Yes. HealthKit access is granted by category, and iOS lets you review or change app permissions later.
