AllerLens

AllerLens reads a restaurant menu, translates it, and checks every dish against the allergens you chose. Point your camera at the menu, one page or several. If there is a QR code on the table, point the camera at that instead and the menu opens inside the app. You can also paste a link to the menu, or upload a PDF or photos of it. Each dish is marked Safe, Caution or Avoid for your allergens. When a dish has no description, AllerLens works out what it normally contains from how the dish is usually made. When it knows nothing about a dish, it marks it Ask staff and never calls it Safe. WHAT IT DOES • Scan a printed menu with your camera, up to five pages at a time, and get one combined menu • Open a menu from the QR code on the table or from a link, then tap Read this menu • Upload a PDF menu (the first 10 pages are read) or photos from your library • A note that covers the whole menu, such as a shared fryer or "all dishes contain...", is applied on every page; a line about the frying oil is applied to fried dishes • Translation into English or Spanish, shown alongside the original text • Nine allergens: peanuts, tree nuts, dairy, eggs, gluten, soy, fish, shellfish, sesame • Every flagged dish shows which words triggered the flag and why • Flags allergens a dish usually contains even when the menu lists no ingredients • Dishes that change daily, like the soup of the day, and dishes that point to a list the app did not see (sauces, dressings, sides) are marked Ask staff • Dishes with more than one price show every price • Prices in the currency the menu prints • Save scans by restaurant and keep the dishes worth remembering • The app itself in English or Spanish, following your phone • Light and dark appearance RELATED ALLERGENS AllerLens flags squid, octopus and cuttlefish as Caution for anyone with a fish allergy. It treats tree nuts and peanuts as related, and warns when fried dishes may share a fryer with seafood. NO ACCOUNT There is no sign-up and no sign-in. Your allergen profile and scan history are stored on your device, and your allergen profile is never sent to us. Menu photos, PDFs and the text of menu pages go to our server and our AI providers only to read that menu, and are then discarded. Photos are sent when you tap Done, and a menu page when you tap Read this menu. A menu link opens straight from the restaurant's website, and the link itself is never sent to us. If you report a problem with a result, a short anonymous report (the dish name and the label shown) is sent so we can fix mistakes. You can erase everything on your device at any time from Profile → Clear scans and settings. LIMITS AllerLens uses AI, and AI makes mistakes. It can misread a menu, miss an ingredient that isn't written down, or misjudge how a dish is prepared. Use it to decide what to ask, and always confirm ingredients and preparation with restaurant staff before you order, especially if your allergy is severe.
