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!

Verdict
The clearest difference is in-app purchases: Lectin Light at none against FODMAP & Allergy's 10. Lectin Light also leads on ads (none vs shown) and rating (5.0 vs 4.8). FODMAP & Allergy's advantage is review sentiment (88% vs 67%) and ratings volume (204 vs 4). On price, update cadence and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. FODMAP & Allergy sells 10 in-app purchases, starting at $3.99 per month. Lectin Light asks for nothing beyond the download.
Lectin Light holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: FODMAP & Allergy has 204 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 88% of FODMAP & Allergy's written reviews are positive against 67% of Lectin Light's, so the app with the better star average is not the one people write more warmly about.
FODMAP & Allergy ships an update every 4 days, Lectin Light every 5 days. Both last shipped on November 3, 2026.
