Editorial policy

The BodySignals Library explains posture, sitting, walking and back health with the evidence behind each claim. This page sets out how articles are chosen, written, checked and updated, and how the library relates to the BodySignals app.

Who writes the library

The library is published by BodySignals, an app made by an independent developer. Articles are signed “BodySignals editorial”. They are researched and drafted with the help of AI tools, and every factual claim is checked against the source it cites before an article is published. No article has yet been reviewed by a medical professional; each page says “Medical review pending” until one has, and the name of any reviewer will be shown on the page.

How topics are chosen

Topics come from the questions people ask about posture and back pain, from the measures the app uses, and from reader suggestions. Every planned topic has an outline first. Outlines are visible but kept out of search results until the article is written.

How articles are written

1. Sources first. Each article starts from systematic reviews, meta-analyses, randomised trials and clinical guidelines, then larger cohort and cross-sectional studies. Single small studies are used with care and labelled as such.
2. Claims match sources. Numbers are taken from the study itself, and the article says what kind of study it is and who was studied. Where a source does not support a claim, the claim is removed or softened.
3. Uncertainty is stated. If the evidence is weak, mixed or missing, the article says so, including when it contradicts common advice.
4. Evidence labels. Each article carries a label from strong to expert opinion. See how to read our evidence labels.
5. Safety. Articles about symptoms say when to see a clinician. See the disclaimer.

The checking process is described in how we check claims.

The library and the app

BodySignals sells an app that measures posture with AirPods. The library mentions the app where it is relevant, in clearly marked boxes, and links to it at the end of pages. It does not change what the evidence says to suit the app. Where the app uses a threshold or a score, the library says it is a product setting, not a clinical cut-off. The library carries no advertising and no paid placements, and BodySignals does not sell any of the products or supplements discussed.

Updates and corrections

Each article shows the date it was last updated. Articles are revised when important new evidence appears or when a reader points out an error. Substantive changes are listed on corrections and updates.
