FODMAP by Fieldnote helps you find the foods behind your gut symptoms — without the noise. Most food diaries ask what you ate. FODMAP by Fieldnote asks what was in it. Build each meal ingredient by ingredient from a database of 180+ foods, and watch the FODMAP load add up as you go. Over time, the app connects what you eat to how you feel — and surfaces the patterns you'd never spot on your own. WHAT YOU CAN DO • Log meals ingredient by ingredient, with the FODMAP load for every item • Track symptoms, drinks, movement, and how you're feeling • See your triggers ranked by how much they shift your next-day symptoms • Follow trends over weeks on a clear, calm timeline • Export a shareable report — with questions for your dietitian BUILT FOR THE ELIMINATION DIET Whether you're starting a low-FODMAP elimination, reintroducing foods, or just trying to understand your gut, FODMAP by Fieldnote keeps the focus on evidence — your evidence. WORKS WITH APPLE HEALTH Connect Apple Health to bring in sleep and cycle data, so you can see how they line up with your symptoms. Your meal logs can be saved back to Health, too. You're always in control of what's shared. PRIVATE BY DESIGN • No account. No sign-up. No cloud. • Everything you log stays on your iPhone. • Nothing is sold, shared, or sent to a server. • Export your data any time. Free to download. A field notebook for your body — quiet, accurate, and yours. Fieldnote makes calm, private health tools for iPhone. FODMAP by Fieldnote is not a medical device and does not provide medical advice. Always consult a qualified clinician about your symptoms and diet.

Your deck. Your pain. One rule: finish it. Hit the Deck turns a plain deck of cards into the most unpredictable workout you'll ever do. Draw a card — the suit picks your exercise, the number picks your reps. Face cards are 10. Aces are 25. The Joker? Fifty. He laughs at you. Survive all 52 and hit the deck one last time. THE GAME • Five built-in decks, from Super Basic to The Destroyer • Build your own: your exercises, your suits, your rules • Wild Card mode: the deck picks, you suffer • Today's Deck: the same 52 cards for everyone on Earth, every day • Boss finale, curses & blessings, combo streaks, slam-to-finish THE DEALER A voice with opinions calls your cards, roasts your quit attempts, and loses his mind when the Joker shows. Your music never stops — the Dealer ducks in and out like a proper DJ. THE META-GAME • Streaks with a Streak Shield — one missed day a week, forgiven • XP ranks and a trophy case with zero participation trophies • A 30-day grid of every deck you've destroyed • Personal records, daily challenges, share cards built for bragging DUEL MODE One phone, two rivals, one shared deck. Pass and play, winner takes the crown — literally. ON YOUR WRIST Full Apple Watch app with complications. Log workouts to Apple Health (duels stay between you and your rival). Inspired by the legendary 52-card jail-cell workout. No accounts, no ads, no data leaves your phone. Completely free.
