Journal Timeline

Updated February 22, 2026

Journal Timeline is the execution ledger for dose events and stack session adherence.

What Journal shows

Journal groups events by day and can include three event types: individual dose events, bundled nutrient events, and stack session rows.

Stack session rows show planned doses, logged doses, missed windows, and day-level adherence.

Journal merges local dose events with HealthKit supplement dose reads across the current window.

Local events stay visible even when HealthKit write calls fail.

The default window spans roughly the last fourteen days.

This keeps the view short enough for weekly review but long enough to see repeat misses.

Use Journal as your source of truth for execution before changing recommendation inputs.
