FODMAP by Fieldnote

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.

Bloating, gas, and IBS symptoms often show up HOURS — even days — after the food that caused them. That delay is why you can't spot the pattern yourself, and why ordinary food diaries don't help: they just hand you weeks of logs to analyze. BellyCue does the analyzing for you. Meet Cue, your friendly gut-signal buddy. Over a focused 14-day test, you log what you eat and how you feel in seconds — and Cue connects your symptoms back to the foods you ate 2–72 hours earlier, then shows you your likely triggers. NOT JUST ANOTHER FOOD DIARY • Cue compares how often symptoms follow a food versus when you DON'T eat it — so real triggers stand out, even if you have symptoms often. • Separates "possible" from "confirmed" triggers as your data grows. • Builds a personal "likely safe foods" list, so you know what you can enjoy. LOG IN SECONDS • Type, speak, or snap a photo of your meal. • Track symptoms (bloating, gas, pain, cramping, nausea, reflux, fatigue). • Bristol stool scale for bowel movements. • Daily mood check-ins. UNDERSTAND YOUR GUT • A clear weekly report of what changed and what correlated. • Ingredient + FODMAP awareness (garlic, onion, lactose, gluten, and more). • Works for almost any food — even ones not in our database. BUILT FOR REAL LIFE • A clean PDF report to share with your doctor or dietitian. • Gentle daily and weekly reminders. • Your data stays on your iPhone. No account required. PERFECT FOR • People with IBS, chronic bloating, or digestive discomfort • Suspected food intolerances (lactose, gluten/wheat, FODMAPs) • Anyone doing a low-FODMAP or elimination diet • Preparing for a GI or dietitian appointment BELLYCUE PRO Unlock your full Trigger Report, unlimited history, weekly insights, your safe-foods list, doctor PDF export, and photo + voice logging. Try it free for 3 days, then $29.99/year — or $5.99/month. Important: BellyCue is a wellness and tracking tool, not a medical device. It does not diagnose, treat, or cure any condition.
