This update focuses on accuracy, safety, and making the app easier to use. Today's read now has its own place in the menu, with last night's score on the row itself, so it no longer sits behind the Apple Health screen. The hours-slept field also states plainly whether an entry has been saved, instead of implying a typed number is already in use. Readings now distinguish complete, partial, and unavailable data. Missing signals no longer produce a full score, and history comparisons appear only when the underlying data are comparable. Stack guidance now follows the catalog's profile-specific pregnancy, trying-to-conceive, and breastfeeding holds and cautions. Book-backed entries such as creatine and rapamycin resolve correctly, and each Stack row more clearly explains what opens when you tap it. The Map starts with practical priorities and makes the detailed framework easier to navigate. Onboarding, menus, sheets, and touch targets were tightened across small iPhones and larger text settings. Ask is more reliable, shows a no-key sample, explains Anthropic usage costs, and discloses the exact on-device context sent when you choose to ask. The app remains local-first and has no subscription, in-app purchase, analytics, or advertising. The Learn and Settings surfaces now link to the published peer-reviewed Hypothesis and Theory paper underlying the framework while clearly separating the framework's hypotheses from what a phone or watch can measure.

Fixes and corrections. The key setup screen now works properly on touch, so pasting your Anthropic key does what it should. Corrected several chapter references that pointed readers to the wrong chapter of the book, including the daily inputs card. Corrected the vitamin C and vitamin D guidance to match the book exactly. Clearer, more accurate wording about what stays on your device and what is sent to Anthropic when you ask a question. Removed a study citation that could not be verified.
