A free iPhone and iPad app: a zoomable, connected map of 249 sourced topics on the human body, vitamins, minerals, food, ingredients and evidence. Coming soon to the App Store, or try it live in your browser.
Body Unpacked: Health Atlas is a free health-education app for iPhone and iPad, coming soon to the App Store. Pick one of 44 foods and follow its nutrients (USDA data) to their established roles and the places in your body where they happen; step through digestion, breathing and reflexes in the Physiology Lab; and see how strong the evidence is behind six popular health claims. Every claim names its source.
Yes. Body Unpacked will be a free download with no ads, no account, no sign-up and no in-app purchases. Every topic, lab module, quest and the Label Lab are included.
Yes. The live explorer on this website runs the same 249 sourced topics as the app, right in your browser, as an infinite zoomable map with expeditions, daily recall and a meal map. The iPhone app adds the Body Connections Explorer, the Physiology Lab, the Evidence Lens, a photo label reader, a private workspace and full offline use.
Every topic carries at least one sourced claim with an evidence label (established, strong, moderate, limited, emerging, regulatory or insufficient). Sources include the NIH Office of Dietary Supplements, USDA FoodData Central, the US FDA, the National Academies, EFSA, the World Health Organization, Cochrane and peer-reviewed journals. Content is checked by the developer against the cited sources and has not been independently reviewed by a clinician. Citing an organization does not mean it has reviewed or endorsed Body Unpacked.
All 13 vitamins, every essential mineral, protein, carbohydrate, fats, fiber and water; the major organs and body systems; digestion, metabolism, hydration and sleep; 44 common foods with USDA FoodData Central values; food additives such as preservatives, emulsifiers, sweeteners and colors; personal care ingredients; and evidence literacy like hazard vs. risk and correlation vs. causation.
Yes. All learning content and artwork are bundled inside the app, so it works with no internet connection. Each claim names its source so you can look it up yourself.
Pick a photo of an ingredient list. Apple's on-device text recognition reads it, and Body Unpacked explains each ingredient it recognises: what it is, why it is used and how it is regulated. The photo never leaves your phone.
No. Body Unpacked is about understanding, not restriction. It never rewards eating less, weight loss or fasting, has no streak pressure, and a Calm reference mode hides the game layer entirely.
No. Body Unpacked is for general education only. It does not diagnose, treat or replace advice from a qualified health professional.
Yes. The app collects no data. There are no analytics, ads or tracking, and anything you log stays on your device.
