A decade ago, travel meant carrying a guidebook, a paper map, and a separate currency converter. Today, a handful of well-chosen apps can replace all of that — and add capabilities no guidebook ever had. Here's what's actually worth having on your phone.
Flight Tracking and Booking
Google Flights remains the best starting point for fare research. Its flexible date grid, price tracking, and "Explore" map make it the most efficient way to find where and when to fly cheaply.
Skyscanner complements Google Flights by covering additional booking sources and regional carriers, particularly useful for routes within Asia, Eastern Europe, and the Middle East.
Flighty (iOS) and App in the Air provide real-time flight status, gate changes, and delay predictions that are often more accurate and faster than airline apps themselves — useful for tight connections.
Accommodation
Booking.com and Airbnb cover most use cases, but don't overlook Hostelworld for budget travel and Agoda for parts of Asia where it often has better rates and availability than Western platforms.
Navigation and Maps
Google Maps works almost everywhere, but Maps.me and Organic Maps download offline maps that work without data — essential for hiking, remote regions, or avoiding roaming charges.
Citymapper is unmatched for public transport navigation in the cities it covers (mostly major global cities), showing real-time departures and the fastest multi-modal routes.
Translation
Google Translate now supports offline packs, conversation mode, and camera translation (point your phone at a menu or sign). For languages with different scripts, the camera feature alone is worth the download.
DeepL often produces more natural translations for European languages and is worth having as a second opinion for anything important (contracts, medical information).
Currency and Money
XE Currency gives accurate, offline-capable exchange rates — useful for quickly sanity-checking whether a price is reasonable.
For spending, multi-currency cards (Revolut, Wise, Monzo) let you spend at the interbank exchange rate without the markups traditional banks apply to foreign transactions. Setting one of these up before a trip is one of the highest-value five-minute tasks a traveler can do.
Connectivity
Airalo and similar eSIM apps let you buy local data plans before you land, avoiding airport SIM card queues and roaming fees entirely. Most modern phones (iPhone XS and later, most Android flagships from 2019+) support eSIM.
Itinerary Management
TripIt automatically builds an itinerary by scanning confirmation emails forwarded to it — flights, hotels, car rentals, all organized chronologically with a single view, including time zone conversions.
Local Discovery
Beyond TripAdvisor (still useful for avoiding genuinely bad options), apps like Wanderlog let you build collaborative trip itineraries with maps, and local guides on platforms like GuruWalk (free, tip-based walking tours) can be a great way to orient yourself in a new city on day one.
The Honest Minimal Set
If you only install five apps before a trip:
- Google Maps (with offline maps downloaded)
- Google Translate (with offline language packs)
- A multi-currency card app (Revolut/Wise)
- An eSIM app (Airalo)
- TripIt (for itinerary management)
Everything else is a nice-to-have depending on your trip style.
Once your apps are sorted, the next step is finding the flight itself. AirHuntr tracks airline deals and flash sales so you can book the trip these apps will help you run.
