Tagging nights with events

Label habits like a late meal or alcohol and measure their impact.

Updated 2026-06-28

Events let you label whole nights with habits — "Large dinner", "Alcohol", "Late workout" — and then see how each one shifts your metrics.

Create and apply a tag

  1. Open a session and add an event tag, or create a new event type with a name and colour.
  2. Turn on auto-apply for an event type to have it tagged onto new sessions automatically.
  3. Tags are reusable across every night.
The event impact panel compares nights with a tag against nights without it.
The event impact panel compares nights with a tag against nights without it.

Reading the impact

  • With vs without — average ODI, heart rate, and CVHR for tagged nights versus the rest.
  • Delta — the difference between the two cohorts (with − without).
  • Carryover — how the effect decays over the 0–3 nights following an event.

Impact comparisons are observational — they show association across your own nights, not proof of cause. Treat them as hypotheses to test.
