Never worry about intolerances, allergies or other dietary restrictions again. You now know in seconds whether you can tolerate a product or not in any situation! No matter whether it's a product, recipe or whatever. "Perfect and unique app without unnecessary bells and whistles for people with histamine problems. The barcode scanner is great, works quickly and easily when shopping. The ability to scan ingredient lists is particularly noteworthy. Thank you very much" - Symera, App Review What can the InTolerApp do? The InTolerApp supports you with all your allergies & intolerances by allowing you to scan barcodes & ingredient lists directly with two practical scanners and immediately see the result / compatibility. After installation, simply select your intolerances, allergies and other dietary restrictions and get started right away. You can use the search function to quickly find or look up foods you can tolerate (e.g. fruit, vegetables or spices) or processed foods (e.g. Nutella). You can also give each food its own rating, which then flows directly into the results of the scanner. This means that the InTolerApp is always tailored to you. It is also possible to set products that are tolerable for you, but would be filtered out due to your filters, as tolerable and thus improve your diet step by step. This prevents you from slipping into malnutrition. Special grace period filters also offer you a perfect start after a new diagnosis. Which intolerances & allergies are supported? Basically almost everything is supported, if something is missing, just contact support! An excerpt: - Low FODMAP - Histamine intolerance - Lactose intolerance - Fructose intolerance - Gluten - Sorbitol intolerance - Xylitol intolerance - Mannitol intolerance - Milk allergy - AlphaGal - Pork - Cross allergies (e.g. to grasses or pollen) - Wheat, barley etc. - Soy - Glutamate - Oxalic acid - Sulphites - Nuts of all kinds - Flavor enhancers - sweeteners - all other important allergens Also filters for vegetarians, vegans and pescetarians. Many other filters and settings. If a list is missing, I will be happy to add it shortly. Who is behind the app? My name is Jonah and unfortunately I have been suffering from histamine intolerance for several years. For this reason, I developed the app for myself to make my everyday life easier, as there was no good app available before. In the meantime, after a successful histamine diet with a phase of restriction and build-up, I feel much better and I can eat almost anything again without having to worry about symptoms (you can find an explanation of how to do this in the app). When I uploaded the app to the App Store, the feedback was so positive and good that I got even more involved with it and delved deeper into the technical and nutritional aspects. The result is the InTolerApp version 2.0. If you have any questions or problems, you can contact me at any time by email at mail@intoler.app or by WhatsApp at +49 231 86443177. I look forward to your message! ------------------------------- The data for the barcode scanner comes from the OpenFoodFacts database (ODBL License). Thank you very much!

What's really in it? Point your camera at an ingredient list and ScanGredients tells you. Made for the grocery aisle: for careful label readers and anyone shopping for someone else. HOW IT WORKS • Snap the ingredient list. If it wraps around the box, add more photos, up to six. • Check the text we read and fix anything that looks off. Nothing is used up until you tap Check ingredients. • Get the result in seconds: allergen words first, a simple 1 to 5 score, how processed it is, and every ingredient explained. ALLERGEN WORDS, HIGHLIGHTED • Choose the allergens you watch for: milk, eggs, peanuts, tree nuts, wheat, gluten, soy, sesame, fish, shellfish and more. • ScanGredients highlights those words when they appear in the label text it reads, and keeps "may contain" statements separate. • Allergen word highlights are free and work on your phone as soon as the label is read. • It only reads the text you photograph or type and can miss things, so it never replaces reading the package. EVERY INGREDIENT, EXPLAINED • Plain-language notes on additives, sweeteners, oils and emulsifiers. • A processing level from whole food to ultra-processed, based on the NOVA classification. • Good stuff and watch-outs at a glance, with links to look things up. KEEP IT ALL • My Scans saves every label you check. • Search thousands of ingredients in the Ingredients library. SCANGREDIENTS PLUS Your first full check is free. Plus unlocks unlimited checks and the full ingredient library, billed monthly or yearly, and new subscribers start with a 7-day free trial. Payment is charged to your Apple ID. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings. PLEASE NOTE ScanGredients uses AI to read labels and can make mistakes. It gives general food information, not medical or allergy advice, and it does not tell you whether a food is safe for you. Always read the package, and ask your doctor about allergies. No account needed.

Verdict

The call

The clearest difference is ads: ScanGredients at none against FODMAP & Allergy's shown. ScanGredients also leads on review sentiment (100% vs 88%). FODMAP & Allergy's advantage is rating (4.8 vs 4.3) and ratings volume (204 vs 13). On price, update cadence, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. FODMAP & Allergy sells 10 in-app purchases, starting at $3.99 per month and ScanGredients sells 2 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

FODMAP & Allergy holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: FODMAP & Allergy has 204 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 88% of FODMAP & Allergy's written reviews are positive against 100% of ScanGredients's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

FODMAP & Allergy ships an update every 4 days, ScanGredients every 6 days. The most recent releases landed on November 7, 2026 and November 10, 2026 respectively.
