The Stack

Layers thatcompound.

Passive signals, proxy DLMO, TipTraQ validation, daily dose cues — four layers, each sharpening the estimate.

  1. Layer 1

    Passive signals

    Your phone reads light, movement & sleep — passive.

    • Background light & screen-on
    • Accel. sleep & wake timing
    • Social jet lag on the surface
  2. Layer 2

    Proxy DLMO

    Melatonin onset from wearables — no lab or saliva.

    • Sleep + chrono test answers
    • On-device phase anchor + band
    • Actigraphy–DLMO corr. (~r 0.8)
  3. Layer 3

    Physio validation

    Three home nights upgrade proxy — clinical-grade.

    • TipTraQ temp, HRV, and SpO₂
    • Verified clinical-grade badge
    • Wellness signal → research
  4. Layer 4

    Personal dose cues

    Six cues move when phase drifts — not fixed alarms.

    • Light, food, meds, movement
    • BTI take-now windows for meds
    • One plan on your dashboard
