Apps Every Traveler Should Have on Their Phone
You don’t need 30 travel apps. You need about 8, and you need them downloaded before you leave, not when you’re standing in a foreign airport with no data.
This isn’t a “top 50 travel apps” list. These are the ones I actually use on every trip, organized by what they do.
Getting around
Google Maps (or Apple Maps)
You already have one of these. The thing most people don’t do: download offline maps before you leave. In Google Maps, search for the city, tap the banner that says “Download,” and grab the whole metro area. In Apple Maps, go to your profile and tap “Offline Maps.” This takes 2 minutes at home and saves you when you’re underground, in a dead zone, or your eSIM hasn’t kicked in yet.
Google Maps is better for transit directions in most cities. Apple Maps is better for walking directions and looks cleaner. Use whichever you prefer, but download the offline version.
Citymapper
If you’re going to London, Paris, Berlin, Madrid, Barcelona, New York, or any of the other 100+ cities it covers, Citymapper is better than Google Maps for public transit. It shows you real-time departures, platform numbers, which end of the train to stand on, and exactly when to get off. It also tells you the fastest route versus the cheapest one, which matters in cities like London where the Tube can be twice the price of a bus for the same trip.
Not useful everywhere. Check if your destination is covered before you download it.
Communication
Google Translate
The camera mode is the killer feature. Point your phone at a menu, a sign, or a train schedule, and it translates in real time through the camera viewfinder. It’s not perfect, but it’s good enough to figure out that the third item on the menu is pork, not fish.
Download the language pack for your destination before you leave. The offline translation isn’t as good as online, but it works without data, which is when you need it most.
If you’re traveling outside the US, this is how most of the world communicates. Hotels, tour operators, restaurants, taxi drivers. Many businesses outside North America won’t respond to SMS or email but will answer a WhatsApp message in minutes. It’s also how you’ll stay in touch with people you meet on the road.
Money
Wise (formerly TransferWise)
The Wise debit card gives you the real mid-market exchange rate with a small transparent fee (typically 0.35–1% depending on the currency pair). No “3% foreign transaction fee” surprise on your statement — for context, most banks charge 2.5–3% on international transactions, meaning Wise saves roughly $20–30 per $1,000 spent abroad. You can hold multiple currencies and convert between them at market rate. It’s consistently cheaper than using your regular bank card abroad.
Order the physical card a couple weeks before your trip. Add it to Apple Pay so you have a backup if the card gets lost.
Trail Wallet or TravelSpend
If you’re on a budget and want to track daily spending, either of these works. Log each expense, set a daily budget, and see how you’re doing. Both let you switch currencies, which is useful when you’re hopping between countries and can’t do the conversion math in your head anymore.
Most people don’t need this. But if you’re doing a longer trip or backpacking, knowing you’re averaging $45/day instead of your target $40 helps you adjust before you run out of money.
Connectivity
Airalo (or eSIM.me)
Skip the SIM card shops at the airport. Airalo sells eSIMs you can buy and install before you even board the plane. Pick your destination, choose a data plan (usually $5-15 for a week), and activate it when you land. Takes 5 minutes. They cover 200+ countries and have served over 10 million users since launching in 2019.
Check that your phone supports eSIM first. All iPhones from the XS (2018) onward support eSIM, and iPhone 14+ models sold in the US are eSIM-only (no physical SIM tray). Most mid-range and flagship Android phones from 2020 onward support it too.
Regional plans are usually better value than single-country plans if you’re visiting multiple countries. The “Europe” package covers 39 countries and costs less than buying France and Spain separately.
Planning
Tripstitch
For building an actual day-by-day itinerary. Tell it where you’re going and for how long, and it generates a full plan with real places pulled from Apple Maps. You can adjust everything through chat. Swap a museum for a market, push your morning back an hour, add a restaurant someone recommended. The whole plan lives on a map and works offline.
It replaces the “spend an evening reading blog posts and saving Google Maps pins” phase of trip planning. Useful if you want a structured plan without the research hours.
Google Maps lists
For saving specific recommendations. When someone says “you have to try this place,” save it to a trip list in Google Maps. By the time you leave, you’ll have a map full of pins from friends, Reddit threads, and blog posts. It doesn’t organize them into a schedule, but it’s a good way to collect ideas before you plan.
Nice to have
XE Currency
Quick currency conversion. How much is 3,500 yen? Is 45 euros a lot for this? XE works offline and updates rates when you have data. Faster than Googling every time.
Flighty
Flight tracking for people who care about the details. It uses FAA data to show you delays before the airline announces them, tracks your plane’s inbound flight, and alerts you to gate changes. The free version is fine for occasional travelers. The paid version is worth it if you fly more than a few times a year.
Notify
Sends you a notification when specific airlines drop prices on routes you care about. Set it up a few months before your trip. It won’t always find a deal, but when it does, it can save a few hundred dollars on flights.
Before you leave
A quick checklist:
- Download offline maps for every city you’re visiting
- Download language packs in Google Translate
- Buy and install your eSIM so it’s ready to activate
- Add your Wise card to Apple Pay as a backup
- Make sure your planning app works offline so you can check your itinerary without data
Do all of this on your home WiFi. Every single one of these things is harder to do for the first time in an airport.
