Read full description

Calm is a tracker for the Autoimmune Protocol (AIP), the elimination and reintroduction diet. A sourced food guide, a 20-second daily check-in and every food challenge in one place, and your progress drawn as a gut on a night sky: every food you win back becomes a star. DRAW MY GUT Answer a few short questions and Calm draws your gut and shows how many foods each stage holds for you. No account needed. IS IT AIP? A GUIDE WITH ITS SOURCES - 243 foods, each with its status during elimination, its reintroduction stage and its source, quoted word for word: Sarah Ballantyne's published stages (2021), Autoimmune Wellness, Mickey Trescott, NIDDK - Where the sources disagree, Calm shows who says what - Paste an ingredient list to see what is out, what comes back at which stage and what Calm doesn't know - With celiac disease, gluten grains are never offered for reintroduction (NIDDK) - A word Calm doesn't know is "not checked", never "AIP" A 20-SECOND CHECK-IN - How you feel, the areas you track and what you ate in plain words, checked as you type - Sleep, stress, Bristol scale, exercise and notes when you want them - Edit, delete or fill in any past day REINTRODUCTION, ONE FOOD AT A TIME - The challenge day as Ballantyne publishes it: half a teaspoon, a teaspoon, a teaspoon and a half, then a normal portion, with a timer for every wait and a Live Activity on the Lock Screen - Then 5 to 7 days without that food and nothing new, with an evening reminder to check in - No symptoms: the food is back and lands as a star on your gut. Any symptom: "not now", with a date to try again at least six months later. A reaction is never filed as safe. FOR YOUR APPOINTMENT A PDF visit report in date order, up to 12 weeks: each area week by week, the foods back, every reaction with its timing, your medications. Page 1 is always included; the full report adds weekly charts, every challenge's times and the diary. YOUR DATA STAYS YOURS - Your log stays on your iPhone and is never stored on our servers. - Export everything as CSV at any time - No account, no ads, no tracking ALSO Widgets for the Home Screen and Lock Screen, Siri and Shortcuts, a shareable picture of your sky (nothing about your health on it unless you add it), and the app in English, German, Spanish, Dutch, Polish and Swedish. INCLUDED WITHOUT CALM PRO The check-in, the whole guide, the label check, Stage 1 challenges, your sky, 2-week trends, page 1 of the report, the export, widgets. CALM PRO - Challenges at Stages 2 to 4, and foods of your own - Patterns: what your own log shows in the 72 hours after each food, how often and how sure. Patterns describe your log; they never show that a food is the reason for a change. - Trends over 12 weeks and the full visit report - The AI AIP guide: your question goes to xAI (Grok) through our server only after you allow it Calm Pro is a monthly or yearly subscription, or a one-time purchase; prices in your currency are shown in the app. Payment is charged to your Apple Account. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage or cancel them in your App Store account settings. The guide is general information from the named sources, not medical advice, and naming a source does not mean it endorses Calm. Calm does not diagnose or treat any condition. Talk to your doctor or a registered dietitian before starting an elimination diet or changing what you eat.
