Fodmi vs the Monash FODMAP app

The Monash FODMAP Diet app and Fodmi help with different parts of the diet. The Monash app is a reference: look up a food in its traffic-light guide, find certified products and recipes, and keep a diary that walks you through reintroduction. Fodmi starts from what you actually ate: photograph your plate, see the whole meal’s FODMAPs across the six groups, and check in a few hours later on how it sat. If you want to look foods up, the Monash app is built for that. If you want each meal worked out for you, and your own patterns over time, that is what Fodmi does.

We make Fodmi, so take our view with that in mind. Everything below about the Monash FODMAP Diet app comes from its US App Store listing, which we read on 28 October 2026. Listings and prices change; check the current one before you decide. Fodmi is not affiliated with or endorsed by Monash University.

What the Monash FODMAP Diet app does

The app comes from the research team at Monash University that developed the low FODMAP diet. Its listing describes a food guide covering hundreds of foods with a traffic-light system, a list of branded products Monash has certified as low FODMAP, more than 70 recipes, a shopping list, and notes you can add to foods. It explains the diet and its three steps with tutorials. Its diary records what you ate, your symptoms, bowel habits and stress, and guides you through the second step, reintroducing foods.

It’s a one-off purchase with no subscription, on iPhone and iPad, and you can switch between metric and imperial units. Its listing doesn’t mention logging a meal from a photo or your voice, scanning barcodes, or adding up the FODMAPs across a whole meal, so you look foods up one at a time.

What Fodmi does

Fodmi starts from the meal on your plate. Take a photo, say what you ate, or type it. Fodmi picks out the ingredients, including hidden garlic and onion, and shows the whole meal across the six FODMAP groups, because FODMAPs from different foods add up. A few hours later it asks how the meal sat, so over a few weeks you can see which foods line up with bad days. You get weekly trends and a PDF report for your doctor or dietitian, and you can look up more than 900 foods with the amount where each stays low (see the food list).

It also scans packaged food: scan the barcode, or photograph the label if the barcode isn’t found, and Fodmi rates each ingredient and tells you whether the amount you’ll eat is low.

What it doesn’t do: there’s no recipe collection, no list of certified products, and it’s iPhone only. How Fodmi works out its answers.

Which should you pick?

• Just starting, and want to learn the diet from the people who developed it? The Monash app’s tutorials and food guide.
• Want recipes, or a list of certified products to shop from? The Monash app.
• Want a whole meal’s FODMAPs worked out from a photo, without looking up each ingredient? Fodmi.
• Holding a packet that isn’t certified? Fodmi scans its barcode or label.
• Trying to see which meals line up with bad days, or need a report for your doctor? Fodmi’s check-ins, trends and PDF report.
• Prefer to pay once? The Monash app is a single purchase; Fodmi is a subscription.

Plenty of people use both: a food guide to look things up, and a meal log for what they actually eat and how it sat. For more apps, see the best low FODMAP apps for iPhone. Whichever you use, the diet works best as a short trial followed by reintroduction, ideally with a dietitian. Our guide to the low FODMAP diet explains the three phases.
