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.

Bad gut days can feel random — until you see the pattern. BowelApp helps you spot which foods line up with rough days, track how your gut changes week to week, and walk into your next appointment with a clear record instead of a guess. Built for people living with IBS, IBD or sensitive digestion — and anyone who just wants to understand their gut. Everything stays on your iPhone. No account, no sign-up. GROUNDED IN RESEARCH, NOT GUESSWORK Every "normal" range comes from a cited clinical source — the Bristol Stool Form Scale, Rome IV frequency ranges and transit-time research. Open the built-in Sources screen any time to see exactly where each number comes from. If we can't cite it, we don't show it. FREE — EVERYTHING YOU NEED TO TRACK AND UNDERSTAND • Log a movement on the Bristol Stool Scale in one tap — add urgency, pain, blood, mucus or a note only when it matters • Log meals as quick text with food tags, so triggers surface next to symptoms • Note your day: sleep, stress, exercise, hydration, illness or travel • Your frequency vs research-based normal ranges, and your own baseline — "your usual" — after a couple of weeks • An 8-week chart, Bristol consistency mix, symptom trends and a calm safety summary that flags when something's worth a doctor's visit • A free Weekly Insight, written from your own logs PRO — LET THE AI DO THE PATTERN-SPOTTING • Unlimited AI insights, on demand: plain-language observations that connect the meals you logged to the symptoms that followed, and point to what's worth raising with your doctor • By weekday — see which days tend to run looser • Morning rhythm — learn when your gut usually wakes up Try one AI insight free. Prefer not to subscribe? Buy single insights as you go. PRIVATE BY DESIGN • 100% on-device storage — no cloud database, no copies of your data • No account, no email, no ads • AI insights send a one-time summary for processing — never stored, never linked to you • Delete the app and your data is gone WHO IT'S FOR • People living with IBS, IBD or other chronic bowel conditions • Anyone preparing for a GI appointment who wants a clear log to share • People doing an elimination diet, tracking food alongside symptoms • Anyone curious whether their gut is "normal" BowelApp is a tracking and education tool. It does not diagnose, treat or provide medical advice. Always talk to a qualified healthcare professional about your symptoms.
