Fodmi vs Spoonful

Both apps scan packaged food, but they start from different places. Spoonful is built around the supermarket scan: point your camera at a barcode and get a green, yellow or red result for low FODMAP and several other diets. Fodmi is built around the meal: photograph what you ate, see its FODMAPs across the six groups, and check in a few hours later on how it sat. Its scanner rates each ingredient of a packet for the amount you’ll eat.

We make Fodmi, so take our view with that in mind. Everything below about Spoonful comes from its US App Store listing, which we read on 22 October 2026. Listings and prices change; check the current one before you decide.

What Spoonful does

Spoonful’s listing describes a scanner. You point the camera at a barcode and get a traffic-light result based on a product’s FODMAP content, which its listing says dietitians have reviewed. The same scan can check gluten, eight common allergens and plant-based diets, suggest alternatives when a product doesn’t fit, and show products other people have scanned and reviewed.

That makes it handy in the aisle, when the question is “can I buy this?” Its listing doesn’t mention logging meals you cook or order, or recording how you felt afterwards.

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 meal across the six FODMAP groups. 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 can also 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: it covers low FODMAP only, and it’s iPhone only. How Fodmi works out its answers.

Which should you pick?

• Standing in a shop with a packet in your hand? Both scan barcodes. Spoonful also checks gluten and allergens and shows other people’s reviews; Fodmi tells you whether the amount you’ll eat is low.
• Cooking at home or eating out, and trying to work out what sets you off? Fodmi.
• Following more than one diet, such as gluten free as well? Spoonful covers several; Fodmi covers low FODMAP only.
• Your doctor or dietitian wants a record? Fodmi’s PDF report.

If low FODMAP is your only diet, Fodmi covers both the shop and the plate. If you shop for several diets, Spoonful’s scan checks more of them, and some people use it alongside a meal log. For how they compare with other apps, see the best low FODMAP apps for iPhone and alternatives to Spoonful. 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.
