Food Sensitivity Tracker Built for Symptom Correlation Not Calorie Counting
People managing celiac, IBS, histamine intolerance, and autoimmune conditions need to correlate foods with delayed symptoms across 1-72 hour windows. Most food diary apps were designed for calorie counting first with symptom tracking bolted on. Users on celiac and gut health forums describe tracking as a real pain and resort to spreadsheets because existing apps don't handle multi-variable elimination protocols.
The non-obvious insight: delayed reactions (12-72 hours) are the whole problem. If reactions were immediate, people wouldn't need an app. Build the correlation engine for delayed multi-variable analysis first, pretty logging UI second.

Triggerbites is the closest purpose-built solution but is new, subscription-based, and unproven. mySymptoms has the analytical depth but terrible UX. The gap is a modern, low-friction tracker that handles multiple intolerance protocols (FODMAP, histamine, AIP) with AI-assisted logging and clear visual correlation timelines.
