Tract

Tract is an iOS app that helps people with IBD, IBS, or elimination diets track meals, symptoms, bowel movements, and food reintroductions to identify possible food triggers.

What is Tract?

Tract is a food and symptom tracking iOS app designed for individuals managing IBD, IBS, or following elimination diets. It takes daily entries of meals, symptoms, bowel movements, and reintroductions as input and outputs ranked possible food triggers and pattern summaries. The app also includes a public recipe library with diet-specific categories like low-FODMAP, IBD-AID, and AIP. Tract does not replace medical care but provides a clearer record for dietary decisions.

Key Features

• One daily record — Meals, symptoms, bowel movements, notes, and reintroductions are logged together in a single daily view, allowing users to see the full context around symptoms.
• AI-powered pattern detection — Daily AI summaries highlight repeat foods, timing, and calmer periods without requiring manual review of every entry.
• Guided food reintroduction — Users can track eating days, monitoring days, and whether a food felt okay before moving on, providing a structured plan for introducing new foods.
• Public recipe library — Browse elimination-diet recipes by meal type (e.g., low-FODMAP dinners, IBD-AID soups, AIP breakfasts) and bring repeat meals into the app for symptom correlation.
• Symptom context view — When a symptom occurs, the app shows the full day's entries including meals, notes, and bowel movements, so users don't have to reconstruct events from memory.
• Dietitian-reviewed blog — Access meal plans, food lists, and tracking tips for IBD, IBS, and elimination diets, all written or reviewed by dietitians.

Who is it for?

• Individuals with IBD (Crohn's disease, ulcerative colitis) — They can track meals and symptoms to identify trigger foods and monitor disease activity patterns.
• People with IBS — They can correlate specific foods with symptom changes and use the reintroduction feature to test tolerance.
• Anyone following an elimination diet (low-FODMAP, AIP, IBD-AID) — They can log reintroduction steps and see which foods are tolerated before moving to the next challenge.
• Dietitians and healthcare providers — They can use the app's clear record to guide patients in dietary management (implied by the dietitian-reviewed content).

What can you do with Tract?

• Independently identify food triggers — Log meals and symptoms daily, then view AI-ranked correlations to see which foods are most associated with symptom changes.
• Safely reintroduce eliminated foods — Use the guided reintroduction plan to track eating and monitoring days, with a clear verdict on whether each food was tolerated.
• Cook from elimination-diet recipes — Browse the public library of low-FODMAP, IBD-AID, and AIP recipes, then log the meal in Tract to see how it affects your own symptoms over time.
• Share a clear record with your doctor — The daily log provides a chronological view of meals, symptoms, and bowel movements, making it easier to discuss dietary patterns during appointments.

How does Tract work?

Users log their meals, symptoms, bowel movements, and reintroductions in a single daily record. The app analyzes this data to rank possible food triggers and show associations with symptom changes. It also provides daily AI summaries that highlight repeat foods, timing, and calmer periods.
