Best Low FODMAP Apps in 2026: Monash, FODMAP Friendly, Fig and Foodsage Compared

Quick answer: use the Monash University FODMAP Diet app for serving-size ratings, because its team developed the diet. Add FODMAP Friendly if you want to find certified products, and a label scanner such as Fig or Foodsage if you want a quick check of packaged foods. The apps do different jobs, and none replaces a registered dietitian.

Foodsage is our app, so weigh that as you read. We describe the other apps from their own App Store listings and websites, as of October 2026. This is general information, not medical advice.

At a Glance: Low FODMAP Apps Compared

Monash University FODMAP Diet App: The Reference

The Monash app's App Store listing says Monash researchers developed the low FODMAP diet and the app to help manage IBS symptoms. It includes tutorials on the app and the three-step diet, a Food Guide that uses a traffic-light system to rate hundreds of foods, a list of branded products certified as low FODMAP by Monash, a collection of over 70 low FODMAP recipes, shopping lists and notes, and a diary for logging meals, symptoms, bowel habits and stress that also guides the reintroduction phase. In the US listing it costs $7.99 with no in-app purchases listed.

Its strength is serving size. A food can be green in a small portion and amber or red in a larger one, which no ingredient scan can tell you. Monash also revises serving sizes over time, so use the current app, not an old list.

FODMAP Friendly: Certified Products

FODMAP Friendly describes itself as the world's first low FODMAP certification, with products independently lab-tested and certified ones carrying a green logo. Its app features, as listed on its site, include finding certified products while you shop, accessing FODMAP data, checking meals with the Recipe Maker, discovering FODMAP Friendly restaurants nearby and finding a FODMAP-trained practitioner near you. Its site does not mention barcode scanning or a price. Monash and FODMAP Friendly are separate programs and can rate the same food differently, so pick one reference and stick to it.

Fig and Foodsage: Checking Packaged Foods

Packaged foods are where hidden FODMAPs show up: inulin and chicory root fiber, high-fructose corn syrup, and onion or garlic powder and extracts. Scanning apps help with that first pass.

Fig lists Low FODMAP among the diets it supports, builds your profile from a short questionnaire and, per its App Store listing, checks a barcode in under a second. See our Foodsage vs. Fig comparison for the differences.

Foodsage lets you choose FODMAP as a custom sensitivity, alongside dairy, gluten, nightshade and soy, plus conditions such as IBD and avoid categories such as additives and seed oils. Each scan returns a verdict and the ingredients that matched. It checks ingredient lists, not serving sizes, so we suggest using it with Monash, not instead of it. Our Monash vs. Foodsage guide explains how to use them together.

How to Use Them Together

1. Cooking at home: use Monash to check foods and portions and to log symptoms.
2. Shopping: use a scanner such as Fig or Foodsage to flag common FODMAP ingredients in packaged foods, then check anything borderline in Monash.
3. Buying convenience foods: look for FODMAP Friendly or Monash certified products when you want a tested option.
4. Always: work through the elimination and reintroduction phases with a registered dietitian.
