Skills to Master
Translation apps are great, but they’re only as helpful as the way you use them. We’ll show you the simple, practical skills that help you scan menus, ask the right questions, and spot red flags so you can eat safely and travel confidently. These skills transform apps into travel superpowers:
Skills to Master
- Download the languages you need to use it offline if required.
- Short, Clear Phrases Only apps work best with simple language so avoid long sentences
- Always Back-Translate to check accuracy by translating back into English
- Favourite or Screenshot key phrases so you can quickly access your most used phrases
- Ignore Slang & Idioms, apps often misinterpret casual English expressions
- Know When to Say No, If it’s a serious allergy or you don’t feel understood, switch to your printed allergy card
- Pick the right tool know how to use it.
- Be comfortable translating text and audio, YouTube videos in another language are a good way to get familiar with this
- Be comfortable scanning images so you know what is in a product, a great way to do this is in the international foods section of your supermarket or the local Asian grocery store
- Use Smart Tools That Understand Allergies
- Menu Suitability this tool goes beyond just words. It help filter menu items based on your actual restrictions, giving you a personalised safety boost.
- Meal Suitability Tool Unsure about a dish or label? This image-based tool helps flag ingredients that might not work with your needs.
How to Use Google Translate
When Translation Apps Fail
- Apps might miss cross-contamination or regional synonyms.
- Back-translation helps but it isn’t foolproof.
- Too much reliance on auto-translate can lead to confusion in high-risk scenarios.
For serious allergies, translation apps are great for conversation, but a printed allergy card is your ultimate safety net.
Best Safe-Eating Strategy = App + Allergy Card
Translation apps are flexible and fast. Allergy cards are clear, respectful, and harder to misinterpret. Together, they give you clarity and confidence, whether in a bustling night market or a fine-dining restaurant.

Translating Ingredients and Food Labels
Reading ingredient lists abroad is a different challenge to translating a menu, you’re often dealing with dense small text, unfamiliar scripts, different packaging layouts and technical food terminology that general translation apps sometimes struggle with.
The apps worth using
Google Translate’s camera function (Google Lens) is the go-to for most scripts, point your phone at the label and it overlays the translation in real time. It handles most European languages well and is improving constantly with Asian scripts.
For Japanese, Korean, and Chinese, Papago is worth having alongside it. It’s built specifically for Asian languages and handles food terminology more accurately than Google Translate in our experience.
A tip for before you travel
Find bilingual packaging at your local Asian grocery or international food section, many products list ingredients in both English and the local language. It’s a low stakes way to get familiar with the layout and key terms before you’re standing in a foreign supermarket trying to figure out if something is safe.

What’s the difference between a translation app and an allergy card?
Translation apps are flexible and great for conversation. Allergy cards are pre-written, clear, and harder to misinterpret, together they give you the best protection. We go into this in more detail here Allergy Cards vs. Translation Apps when to use them
Are these apps free?
Google Translate is completely free. Papago and DeepL have free versions that cover most traveller needs, with paid upgrades available.
Can I use translation apps to read ingredient labels abroad?
Yes, Google Translate’s camera function is the easiest way to scan and translate ingredient lists in real time. For Japanese, Korean, and Chinese packaging, Papago tends to handle food terminology more accurately than Google Translate.
Are ingredient labels laid out the same way everywhere?
No, and that’s worth knowing before you travel. Western packaging typically lists ingredients in a familiar format, but Japanese packaging for example has a specific allergen declaration section that isn’t immediately obvious if you’ve never seen it before. Practising on bilingual packaging at your local Asian grocery store before you travel is a great way to get familiar with different layouts.
What if I’ve translated the label but I’m still not sure if it’s safe?
That’s where the Meal Suitability Assistant comes in. Take a photo of the meal or packaging, tell it your restrictions, and it gives you a rundown of how safe it is for you specifically — including what to ask if something is unclear. It’s particularly useful when you’re dealing with unfamiliar ingredients or local terms that don’t translate cleanly.
