Evidence & Methods

What we know. What we are still testing.

Daylogue is a system for self-understanding. Pattern journaling is how it reads you: your stress running higher on the nights you logged under six hours. Those observations are designed for reflection, not diagnosis, prediction, treatment, or clinical decision-making. This page separates verified product behavior from research results and future questions.

Product Verified

Confirmed through code review and product QA.

Bench Validated

Tested against a reproducible reference dataset.

Human Tested

Evaluated for comprehension, usability, and safety with consenting adults.

Outcome Supported

Supported by a preregistered controlled human study.

Current validation program

What a Pattern Journal Can Know: Evaluating Self-Report and Apple Health Context in Longitudinal Pattern Detection

Status: Protocol preparation. Technical validation and human-factors testing. This is not a clinical efficacy study.

Initial Apple Health scope

  • Sleep duration
  • Steps and activity
  • Workouts

Held for research

  • Heart rate variability interpretation
  • Resting-heart-rate interpretation
  • Readiness or recovery scores

Approved public claims

Claims appear here only after technical, clinical, and legal/compliance review of the exact wording. A product change or expired approval removes the claim from the active list.

No research or outcome claim has been approved for public use yet. Daylogue will publish results here, including negative or inconclusive findings, after the planned validation work.

Limits and safety

  • • A recurring overlap does not show that one thing caused another.
  • • Missing wearable data is not interpreted as a decline or health change.
  • • Daylogue does not provide readiness, recovery, diagnostic, or medical scores.
  • • Daylogue is not therapy and is not a replacement for professional care.
