An app that translates a menu and flags allergens is doing two jobs, and most of the apps people recommend only do one of them. This is what each of the main options actually does, where each one is the right choice, and where AlignEat is not.
Translation and allergen flagging are two different jobs
Translation turns the words on the page into your language. It does not know that a dish name hides an ingredient, and it has no idea which ingredients matter to you. That is why translation apps, the most common do-it-yourself workaround for eating abroad with allergies, leave you reading a clear menu and still uncertain.
Flagging is the other job: matching every dish against your own profile and saying what looks safe, what needs a question, and what to avoid. Some apps translate, a few attempt both, and that difference decides whether the menu in front of you is merely readable or actually usable. We built AlignEat for the second half.
The options, compared
Six apps, three questions each: what it translates, what it does about your allergens, and who it suits.
App | Translation | Allergen handling | Best for |
|---|---|---|---|
AlignEat | Reads any menu as part of the scan | Sorts every dish into safe, ask and avoid against your profile, flags conservatively, and gives questions to ask staff | Any restriction, any restaurant, before you order |
Allergy Translate | Pre-translated allergy cards in 68 languages, with a voice mode that reads them aloud | Over 75 allergens across multiple profiles; newer versions add an AI menu and packaging scan, though it began as a card app | Telling the kitchen about your allergy in their language |
FoodTranslator | Food and menu translation | Limited evidence of any dietary matching | Reading the menu, nothing more |
Hey Menu | Smart scanner in the translate-and-parse class | Travel utility first, not built around food safety | Convenience on a short trip |
DinePeace | Scans foreign menus, positioned for travel | Flags hidden allergens and sets itself apart from generic translators | Allergy travel with a language barrier |
Menu Ninja | Translation and currency conversion bundled with the scan | A can-eat or cannot-eat list from a photo, a binary verdict rather than a cautious one | A fast answer over a careful one |
Where each one is the right choice
Start with the case where we're not the answer: a traveller with no restriction who only needs to read the menu needs a translator, nothing more.
Allergy Translate is the right choice when the job is telling the kitchen about your allergy in their language: pre-translated instructions, several profiles, and a voice mode that says it aloud. Hey Menu is built for travel convenience rather than food safety, and its allergy search did not work reliably in our testing. DinePeace could not read an Arabic menu in our testing and its free mode skips some allergens, so check coverage before relying on it. Menu Ninja offers translation as soon as the scan finishes, and its can-or-cannot verdict suits people who want a fast answer over a cautious one.
AlignEat, an AI-powered decoder rather than a translator, is the right choice when you have a restriction and want the dish in front of you checked, which is how AlignEat works: the uncertain ones are flagged for a question rather than declared safe.
What none of them solve
Whichever app you carry, a menu only says what is in the dish the way the kitchen chose to describe it. It does not say what shares the fryer, the cutting board or the pan, and no scan can read that. We flag preparation risks where a dish suggests them, and then the kitchen still has to be asked.
The question has to be one a line cook can answer. Ask the chef about the sauce rather than announcing your allergy to the room, and treat an uncertain answer as a no. No automated check is perfect either: the realistic ceiling for menu decoding is 95% to 97%, which is exactly why the questions still matter. Our cross-contamination risk by cuisine reference covers the kitchen side in detail.
Choosing for your trip
Match the tool to the trip, not the other way round:
- Low severity, familiar cuisine. A translator is enough. Read the menu and enjoy it.
- A real allergy in a language you can't read. Carry a scanner that reads the dish against your profile, with the questions to ask the waiter already translated. Hidden soy in a sauce is the classic case, as in eating Chinese with a soy allergy.
- A script you can't match letter by letter, or a handwritten board. Choose a tool that reads photos, QR codes and PDFs, and works offline. Our menu-decoding accuracy improved from 79% to approximately 93% across 300 restaurant menus, which is what makes a scan worth doing before you speak.
- A severe allergy. Carry both: a way to read the dish and a way to tell the kitchen, because they are different jobs.
Frequently Asked Questions
Does Google Translate work for allergy safety abroad?
It translates the words. It does not match dishes to your allergens or flag what a menu leaves unsaid.
Which menu translation apps handle allergies?
Allergy Translate and DinePeace address allergens directly. FoodTranslator, Hey Menu and Menu Ninja are translation and convenience tools first.
