What is the best app to use when traveling?
No single app does everything, but a small set covers almost every trip: Google Maps (or another offline-capable map) for navigation, a translation app such as Google Translate, an itinerary organizer such as TripIt, your airline's app for boarding passes and delays, and one booking app for hotels. For US citizens going abroad, the State Department's Smart Traveler app and STEP enrollment are worth adding.

Tips
- Download offline content (maps, languages, boarding passes) before you leave Wi-Fi.
- Check local apps. Ride-hailing, payments, and messaging apps vary by country, so search what locals use at your destination.
- Keep copies of documents in a secure cloud folder in addition to the originals.
- Secure your accounts. Update apps and use an authenticator app rather than SMS for two-factor codes where possible, in case you can't receive texts abroad.
- Check what's blocked. Some countries block certain services, so confirm your maps and messaging apps work at your destination.
- Don't overload your phone. A few apps you know well beat a dozen you never open.
