How Rewire uses research.
Rewire translates published evidence into practical, readable feedback. The goal is clarity and motivation, not clinical certainty.
Last updated: 7 May 2026
Evidence-informed, not individually measured
Most Rewire feedback is modelled from public research and your logged actions. Unless a device integration or manual log provides a measurement, Rewire is estimating direction and context rather than measuring your body directly.
For example, a smoking recovery timeline may reflect well-known population-level cessation milestones. It does not prove your exact lung function, blood pressure, or disease risk.
Language standard
Rewire should prefer careful wording: may support, is associated with, research suggests, likely direction, and evidence-informed estimate.
The app should avoid claiming that it diagnoses, treats, prevents, cures, guarantees, clinically proves, or medically manages a condition.
Claims and substantiation
Health-related product claims should be truthful, not misleading, and supported by appropriate evidence. The FTC describes this as competent and reliable scientific evidence for health and safety claims.

General wellness boundary
Rewire should stay on the low-risk general wellness side of the line: habit education, general wellbeing, healthy lifestyle support, and non-diagnostic feedback.

Advertising and public copy
UK advertising rules require objective claims to be substantiated and restrict medicinal claims unless the relevant product status supports them.
