The best FODMAP scanner apps for iPhone

Three iPhone apps scan packaged food for low FODMAP. Fodmi scans the barcode or reads photos of the label, rates every ingredient, and tells you whether the amount you’ll eat is low. Spoonful gives a green, yellow or red result for low FODMAP and several other diets, with community reviews and suggested alternatives. Fig checks the ingredients against low FODMAP and more than 2,800 other diets and allergies at once. If low FODMAP is your only diet, Fodmi answers for your portion; if you also avoid gluten or allergens, Spoonful or Fig cover more.

We make Fodmi, so we’ve put it first. Everything below about the other apps comes from their US App Store listings, which we read on 28 October 2026. Listings and prices change; check the current one before you decide.

Fodmi: rated for the amount you eat

Fodmi scans a product’s barcode and looks it up in Open Food Facts. If the barcode isn’t found, you photograph the label instead: the ingredient list first, then the nutrition table. Fodmi reads the ingredients, estimates each one’s share of the product from the order on the pack, and rates them across the six FODMAP groups. Then it tells you whether the amount you’ll eat is low, and warns you not to treat a product as clear when an ingredient isn’t in its food list.

The same app logs whole meals from a photo, your voice or text, and asks a few hours later how they sat, so packets and home cooking end up in one record. It covers low FODMAP only, and it’s iPhone only. How Fodmi works out its answers.

Spoonful: traffic lights for several diets

Spoonful’s listing describes a scanner for people with dietary needs. Point the camera at a barcode, or take a photo, and you get a green, yellow or red result based on a product’s FODMAP content, with support for each phase of the diet. The same scan can check gluten, eight common allergens and plant-based diets. When a product doesn’t fit, it suggests alternatives, and you can browse products other people have scanned and reviewed. Fodmi vs Spoonful goes through the differences.

Fig: one scan for every diet you follow

Fig’s listing describes a scanner that supports low FODMAP and more than 2,800 other diets and allergies, so one scan covers everything you avoid. It can also find suitable foods at grocery stores and restaurants and keep profiles for several people. Fodmi vs Fig goes through the differences.

Lists of certified products instead of a scanner

Two well-known apps take a different route: rather than scanning, they list products they have tested and certified as low FODMAP. The Monash FODMAP Diet app lists branded products certified by Monash, and FODMAP Friendly lists its certified products with filters by country, brand and category. Neither listing mentions a barcode scanner. They’re useful when the brands you buy are certified, and they don’t cover products that aren’t. Fodmi is not affiliated with or endorsed by Monash University or FODMAP Friendly. See Fodmi vs the Monash FODMAP app and Fodmi vs FODMAP Friendly.

Reading the label yourself

No scanner knows every product. When you read an ingredient list yourself, these are the most common sources of FODMAPs in packaged food:

• Fructans: wheat, rye and barley flour; onion and garlic, including powders; inulin and chicory root fibre
• Excess fructose: honey, agave, high-fructose corn syrup, and apple or pear juice concentrate
• Lactose: milk, milk powder, whey and cream
• Polyols: sorbitol, mannitol, xylitol, maltitol and isomalt
• GOS: beans, lentils and chickpeas

Ingredients are listed from most to least by weight, so one near the end of a long list is often a small amount. The amount you eat matters too, and FODMAPs from different foods add up in the same meal.

Which should you pick?

• Low FODMAP is your only diet, and you want an answer for your portion? Fodmi.
• You also avoid gluten or a common allergen? Spoonful.
• You follow several diets or allergies, or shop for a family? Fig.
• The brands you buy are certified? The Monash or FODMAP Friendly product lists.

For apps beyond scanners, 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.

Frequently asked questions

Is there an app that scans barcodes for FODMAPs?

Yes. Fodmi, Spoonful and Fig all scan a product’s barcode and give a low FODMAP answer. Fodmi can also read photos of the label when a barcode isn’t found.

Can a scanner tell me how much of a product I can eat?

Fodmi rates a product for the amount you choose, because many foods are low FODMAP in a small serving and not in a large one. Spoonful’s and Fig’s listings describe a result for the product but don’t mention choosing an amount.

Do these scanners work outside the US?

Fodmi looks barcodes up in Open Food Facts, a worldwide product database whose coverage varies by country, and reads label photos from anywhere. Spoonful and Fig weren’t in the Spanish or Brazilian App Store when we checked on 26 October 2026.

Do the Monash and FODMAP Friendly apps scan barcodes?

Their listings don’t mention a scanner. Both have lists of products they have certified as low FODMAP, which you can browse instead.
