Fennly: Food & Symptom Diary

Bloated after eating and no idea which food is behind it? Fennly is a food and symptom diary that turns your meals into a ranked list of your most likely triggers.

HOW IT WORKS
1. Photograph or describe your meal. Fennly's AI breaks it into ingredients and their likely trigger categories: lactose, fructose, sorbitol, fructans, histamine, gluten, caffeine and more.
2. Log how you feel in seconds: bloating, cramps, fatigue, headache, skin.
3. Read your report. After a few days Fennly ranks your suspected food intolerances, then guides you through an elimination and reintroduction test to confirm them.

FOR BLOATING, IBS AND FOOD INTOLERANCE
Whether you suspect lactose intolerance, fructose malabsorption, histamine intolerance or gluten sensitivity, or you are working through a low FODMAP diet, Fennly does the tedious part for you. No spreadsheets, no guessing, no typing out every ingredient by hand.

WHY FENNLY
- Photo food logging in seconds. Snap the plate and you are done.
- Ingredient level, not just the dish. Fennly knows a pizza is dough, cheese and tomato.
- Fourteen trigger categories, from lactose and gluten to histamine, fructose and caffeine.
- Delayed reactions and the total dose across a day are taken into account, because that is how intolerances actually behave.
- Stress and sleep are factored in, so a bad night does not get blamed on your lunch.
- A guided elimination and reintroduction test with a clear verdict at the end.
- Works offline and syncs when you are back online.
