An offline translator app for travel on iPhone

Last updated October 25, 2026

For travel without a signal, pick a translator that works offline and download your languages before you leave. Passport Buddy Pro lets you download languages and an offline caption model, so translate and transcribe keep working in airplane mode. Test it at home first.

Download before you go

Open Passport Buddy at home on wifi and download the languages you need, plus the offline caption model.

Turn on airplane mode and try speech, text and camera translation. If it works there, it will work abroad.

Charge and storage

Language downloads take space. Check storage and carry a battery pack.

Know the limits

Offline translation can be less accurate than a connected one. Keep important details, like addresses and medical needs, written down.
