Your phone can be the best travel companion you own — but only if you set it up before you leave. The travelers who glide through a strange city aren’t luckier than you; they just downloaded the right apps while they still had home Wi-Fi. You don’t need forty of them. A small, well-chosen kit covers maps, flights, beds, language, money and getting home at night. Here’s the set I recommend: what each is genuinely best at, and where each one lets you down.
Maps That Work Without a Signal
Coverage vanishes exactly when you need directions most, so sort this out before you go.
Google Maps
Still the default for a reason: the best business listings, opening hours and public transport directions in most cities. Save an offline area for your destination and it routes you without data. The honest catch: offline areas expire and need refreshing, and offline directions are more limited than the live version.
Maps.me
Built for offline use from the start, Maps.me shines where Google thins out — hiking trails, village lanes, viewpoints and small paths Google never mapped. It’s also kinder to your storage. The trade-off is weaker business information: restaurant hours and reviews are thinner and can be out of date.
Finding Cheap Flights and Fare Alerts
Google Flights
The fastest way to compare airlines side by side, with a price calendar and tracking alerts that email you when a fare drops. Its one real limitation: Google doesn’t sell you the ticket. It hands you off to the airline or a third-party site to finish the booking.
Skyscanner
Best when your plans are flexible. The “search everywhere” option and whole-month view are brilliant for cheap trips you hadn’t thought of. Just watch the final checkout — some results route through third-party sellers whose prices creep up with fees, and whose customer service is hard to reach.
Booking a Place to Sleep
Booking.com
Probably the widest choice of hotels and apartments anywhere, and its free-cancellation filter is gold when your plans are still shaky. On the downside, the first price you see sometimes grows at checkout with local taxes and fees — compare the final number, not the headline.
Airbnb
Better than a hotel for longer stays, or when you want a kitchen and a washing machine. You also end up in real neighborhoods instead of tourist strips. The catch is fees: cleaning and service charges can turn a bargain into a shrug, and check-in quality depends entirely on your host.
When You Don’t Speak the Language
Google Translate
Download the language pack at home and Translate works fully offline. Camera mode is the party trick — point it at a menu or a street sign and the words change in front of you — and conversation mode handles simple exchanges with drivers and waiters. It’s honest help, not magic: idioms and long sentences come out wobbly, and offline translations are rougher than online ones.
Money: Converting and Spending
Wise
Hold balances in dozens of currencies and spend with the Wise card at the real exchange rate, which quietly saves you a few percent on almost every purchase abroad. Order the card well before you travel, though — delivery takes time, and free ATM withdrawal limits vary by country.
XE Currency
XE converts between every currency you can name, and works offline using the last rates it downloaded. Just remember it shows the mid-market rate; the rate your card or the exchange booth gives you will be a little worse.
Keeping the Whole Trip in One Place
Itinerary apps such as TripIt build one timeline from the booking emails you forward them — flights, hotels, trains — so times and confirmation codes live on a single screen instead of your inbox. Google users get a lighter version of this through Gmail and Google Travel. Either way, check what the app built: automatic parsing occasionally muddles a check-in time, and that mistake becomes yours at the airport.
Getting Around Once You Land
Ride-hailing removes the two worst parts of a foreign taxi ride: explaining the address and negotiating the price. Which app you need depends on the map. Uber covers most of the world, Grab rules Southeast Asia, and Careem is the familiar name across much of the Middle East and Pakistan. Type in your destination, watch the car arrive, pay without cash. The downsides: surge pricing on rainy evenings, confusing airport pickup points, and coverage that thins out fast outside big cities.
Staying Connected: eSIMs and a VPN
Airalo and Travel eSIMs
An eSIM lets you buy a data plan for your destination before you fly and switch it on as you land — no kiosk queue, no tiny SIM card to lose, and your home number stays live for bank codes. Airalo is the best-known marketplace. Two limits: most travel eSIMs are data-only, so there’s no local number for calling a hotel, and your phone must be unlocked and eSIM-compatible.
One Safety Extra: A VPN
A VPN is worth a small subscription for one main reason: airport and hotel Wi-Fi are shared with strangers. It also helps when your bank or a streaming service gets suspicious about a foreign login. Expect slightly slower speeds, and the odd banking app may still demand extra verification.
The Ten-Minute Setup Before You Leave
- Download offline maps for every destination.
- Download the translation language packs while you’re at it.
- Save each hotel’s address in your maps app — and screenshot it.
- Add your travel card to your phone’s wallet as a backup.
- Install your eSIM at home, but activate it when you land — most plans start their validity clock at activation.
- Sign in to every app once, so there are no password surprises abroad.
Frequently Asked Questions
How many travel apps do I actually need?
Eight to ten, counting the ones already on your phone. More than that and you’ll spend the trip scrolling instead of looking around.
Should I pay for premium versions?
Rarely. Free tiers cover most trips. A VPN subscription — and TripIt Pro, if you fly monthly — are the only two upgrades that usually earn their money.
What if my phone dies or gets lost?
Keep confirmations in your email too, carry one hotel address on paper, and keep a second payment method separate from your phone. Apps should be a system, never a single point of failure.
