Quick Answer
Google Translate is the best all-rounder for travel — widest language coverage, offline packs and camera translation. DeepL gives more natural prose for European languages, and Papago is better for Korean, Japanese and Chinese. Download offline packs before you fly.
Translation apps have quietly become the most useful thing on a traveller’s phone. The difference between a good and a bad experience with them is almost entirely setup done before you leave.
Apps and How to Use Them
1. Google Translate — the default, and why
Broadest language coverage, offline packs, camera translation for signs and menus, and conversation mode. Download the language pack before you fly — it works offline only if you do.
2. DeepL — better prose, fewer languages
Noticeably more natural output for European languages. Best for writing an email or reading a document, less useful for pointing at a menu.
3. Apple Translate
Built into iOS with offline modes and on-device processing, which keeps text off external servers. Fewer languages than Google.
4. Papago
Consistently better than Google for Korean, Japanese and Chinese, and the app locals will often suggest in Korea.
5. Camera translation is the killer feature
Point at a menu, a sign, a station board or a medicine packet and read it in place. This is the function that changes a trip most.
6. Offline packs are non-negotiable
Download before departure. Roaming is exactly when you need translation and exactly when you may have no data.
7. Conversation mode, and its limits
Two-way spoken translation works well in a quiet room and poorly in a busy market. Typing is often faster and more accurate than shouting at a phone.
8. Save a phrase card for emergencies
Screenshot your allergies, medical conditions and accommodation address translated into the local language. Screenshots survive a dead connection.
9. Do not use it for anything legally binding
Contracts, visa forms, medical consent and police statements need a human translator. Machine output is good, not reliable enough for those.
10. Learn ten words anyway
Hello, please, thank you, sorry, yes, no, how much, where is, water, and the numbers to ten. It changes how people treat you more than any app.
Setting up properly before you go
Download the offline language pack at home, on wifi. This is the step people skip and then regret at an immigration desk with no signal. Check it actually works by putting the phone in airplane mode and testing a phrase.
Screenshot the essentials rather than relying on live translation: your accommodation address in the local script for taxi drivers, any allergies or medical conditions, and your dietary requirements. A screenshot works with a dead battery on someone else’s phone; an app does not.
Use camera translation for anything written — menus, signs, station boards, ingredient lists on medication. And keep expectations calibrated: machine translation is excellent for getting by and unreliable for nuance, humour or anything with legal or medical consequence.
