Must-have apps and tools for traveling
Offline maps, translation, currency, transit: the app categories worth having before you leave.
Before you leave
| Need | App category | Do it before departure |
|---|---|---|
| Maps | Offline maps (Maps.me, Google Maps) | Download the area over Wi-Fi |
| Translation | Text, photo and voice translation | Download the offline language pack |
| Local transit | The city/country's own app (metro, bus, local ride-hailing) | Create an account before departure if needed |
| Currency | Currency converter | Check the real exchange rate before negotiating |
| Documents | Cloud storage or photos of your papers | Back up passport, tickets, bookings |
Always keep an offline copy (photo or PDF) of your essential documents: internet access isn't guaranteed everywhere.
Connectivity
- Local or international eSIM: often simpler than a physical SIM card, activatable before departure.
- Airplane mode + Wi-Fi: to avoid mobile data roaming outside your plan.
- VPN: useful on public hotel/airport Wi-Fi, or to reach services blocked locally.
Safety and emergencies
- Save local emergency numbers (see the dedicated sheet) and your embassy/consulate address.
- Share your itinerary with someone via a location-sharing app, especially for solo trips or remote areas.
