What this feature does

Feast integrates with Apple Health so supported health and sleep context can be used alongside logged meals when the user grants access.

Why it can be useful

Health integration can reduce manual transfer and align data by date. Authorization remains granular, and missing or inconsistent source data should be expected.

A careful workflow

Use the feature as a reviewable part of your record.

  • Review each requested Health permission before granting it.
  • Confirm that the source device is writing the expected data to Health.
  • Recheck dates and missing nights before interpreting a nutrition-and-sleep pattern.

Limits to keep visible

Convenience and analytical detail do not remove uncertainty.

  • Feast can only use data that exists and that the user authorizes.
  • Consumer health and wearable data contain measurement and classification uncertainty.

Limits and cautions

  • Feast can only use data that exists and that the user authorizes.
  • Consumer health and wearable data contain measurement and classification uncertainty.
  • Features and plan availability can change; confirm the current in-app experience before making a purchase decision.
