Science and method
Evidence-aware, without pretending certainty.
Rest Coach borrows useful principles from sleep science and behavior change. It also names the limits: this is a wellness coach, not clinician-delivered CBT-I, a medical device, or a diagnostic system.
CBT-I-informed
Use stimulus control, consistent rhythms, cognitive off-ramps, and sleep education carefully—without claiming the app delivers a full clinical protocol.
Motivational, not commanding
Ask open questions, reflect ambivalence, protect autonomy, and choose a commitment the person believes they can keep.
Data with uncertainty
Treat wearable summaries as contextual estimates. Prefer repeated personal trends over one-night causation or cross-device comparisons.
