The best apps to find your bloating triggers in 2026
Updated 29 October 2026
For the low FODMAP diet, the Monash FODMAP app is the reference, made by the university that developed the diet. For a detailed food and symptom diary, mySymptoms and Bowelle are well established. Ojafi reads your diary for you and tells you which foods are fine, not just which to avoid. Pick by what you need, not by the longest feature list.

Monash FODMAP Diet
Made by Monash University, where the low FODMAP diet was developed. It rates foods for their FODMAP content and supports the three steps of the diet. If you are doing low FODMAP, this is the food reference to use, ideally with a dietitian.
mySymptoms Food Diary
On the App Store since 2010, one of the longest-running food and symptom diaries. You log what you eat and how you feel, and it shows which foods, drinks and daily factors line up with your symptoms. Detailed, which suits people who want to see the data.
Bowelle
A food and symptom diary built to be quick to use, with visual charts of how you feel over time. It tracks food, symptoms, stress, water and bowel movements.
FODMAP Friendly
From FODMAP Friendly, a certification body for low FODMAP foods. Its food list gives lab-tested foods a pass or fail against its FODMAP threshold, and it is written for people with IBS and for health professionals.
Ojafi
Ojafi is our app, so weigh this paragraph accordingly. It is a food journal built to be read: you log meals and how they sat, and the iPhone app, in review now, looks for the foods and meal times that keep coming before a bad day. It is as interested in the foods that turned out fine, so you can eat them again without worrying. Ojafi does not put anybody on an elimination diet. The journal works in your browser today.
