Apple Health + Rest Coach

Apple Health can collect records from iPhone, Apple Watch, and compatible apps in one permission layer. Rest Coach can use supported daily summaries to understand timing, duration, heart rate, HRV, and activity without asking you to recite every number.

The value is context. If you say you felt exhausted after an ordinary-looking night, the conversation should explore stress, pain, illness, schedule, and measurement limits instead of arguing with you.

Health permissions are granular. You can allow some categories, deny others, or revoke access later in iOS Settings. Rest Coach should remain useful through conversation when no health access is granted.

Connected data should be named when it informs a suggestion. A generic ‘your data says’ is not enough; the source and uncertainty belong in the answer.

Apple Health data does not turn Rest Coach into a medical device or a diagnostic service. Wearable stage estimates and heart metrics need the same caution they would receive outside the app.
