How I Built Tract: A Gut Health Tracking App for IBD, IBS, and Elimination Diets

If you or someone you love has been diagnosed with IBD (Crohn's disease or ulcerative colitis), IBS, or is navigating an elimination diet, you know how overwhelming it can be to track symptoms, foods, and patterns over time.

That's why I built Tract — a gut health tracking app designed specifically for people managing complex digestive conditions.

The Problem

Managing a chronic gut condition means keeping mental track of dozens of variables: what you ate, when symptoms flared, stress levels, medications, bowel patterns, and more. Paper food diaries are tedious. Generic health apps aren't built for gut health nuance. Gastroenterologists and dietitians need actual data to help you — but most patients show up to appointments with nothing but a vague recollection of the past month.

What Tract Does

Tract makes it easy to:

Log meals and symptoms quickly with an intuitive mobile interface
Track elimination diet phases (like the Low-FODMAP protocol) with structured food reintroduction tracking
Identify trigger foods by correlating what you ate with when symptoms appeared
Generate reports you can share with your GI doctor or dietitian
Monitor patterns over weeks and months to understand your condition

Who It's For

Tract is built for people living with:

Crohn's disease and ulcerative colitis (IBD)
Irritable bowel syndrome (IBS)
Anyone doing a structured elimination diet to identify food sensitivities

Why I Built It

As a founder, I was inspired by the gap between the complexity of managing these conditions and the primitive tools available to patients. A proper food and symptom journal is one of the most evidence-based tools for managing gut health — yet the digital tools to do it well just didn't exist.
