About
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.

Hydration now factors drink sub-type (coffee, tea, juice, milk) into FODMAP scoring, with a live level badge as you log. Symptom severity is now rated per symptom with a slider, instead of one overall rating for the day. Symptom and trigger selection use a consistent pill style throughout.
