I’m a former software developer turned full-time travel blogger, and my wife Jess and I have travelled with a smartphone in our pockets since 2010. In the sixteen years since, we’ve watched travel apps appear, get bought, quietly rot, and in a few cases shut down completely. Skype was on the original version of this guide. Microsoft retired it on 5 May 2025, and skype.com now bounces you straight to Microsoft Teams. So rather than a directory of everything in the app store, this is the shortlist that has earned a place on our home screens, tested across years of real trips instead of an afternoon of desk research.
I’ve grouped them by what you’re actually doing on a trip: finding your way around, planning, booking flights and rooms, staying connected and secure, handling language and money, and the bits you reach for once you’re on the ground. Where one of these apps deserves a deeper dive, I’ve linked our full guide to it, because the right eSIM or the right offline map deserves more than a one-line mention. Almost everything here is free. I’ll flag the few that cost money and tell you whether the paid version earns it.

Table of Contents:
Quick Take: The Apps We Reach for First
If you install nothing else before your next trip, start with these. Google Maps for navigation, with Organic Maps downloaded as your offline backup. An Airalo eSIM so you have data the moment you land. WhatsApp for messaging, because in most of the world it’s how people actually reach each other. NordVPN for safe browsing on hotel and airport WiFi. Google Translate for menus and signs. And your bank’s own app, so you can freeze a card in seconds if it goes missing.
Everything below expands on those, plus the planning, booking and photo apps we use trip in, trip out.

Navigation and Getting Around
Google Maps
Google Maps is the one app I’d never leave home without. The features I lean on most while travelling are the ones people forget it has: download an area before you fly and the maps work offline, on the plane and in dead zones; save pinned lists for each city, so the restaurants and viewpoints we’ve researched are all on one map; and check the live busy times before joining a queue. Its weak spot is public transport, which can be a bit patchy outside the big cities. That’s where the next two apps come in.
Organic Maps
Organic Maps is my offline backup, and the app I trust when there’s no signal at all. It’s the community-maintained open-source fork of the old Maps.me, started in December 2020 after Maps.me went from a favourite to an ad-riddled mess. Organic Maps has none of that: no ads, no tracking, no account, just OpenStreetMap data. Download a country before you fly and you get full search and turn-by-turn walking directions with the phone in airplane mode. It passed six million installs in 2025. For hiking and rural areas it often has footpaths and trails that Google simply doesn’t. Grab it from organicmaps.app.
Citymapper
Citymapper is the app to check first in a big city, as long as it covers your destination. It does public transport better than anything else I’ve used: real-time departures, which station exit to take, even which carriage to board so you’re next to the stairs when you get off. That limitation is a real one. It’s city-by-city, around a hundred cities, mostly across the UK and Europe with some in North America and Asia, and it’s been owned by transit company Via since 2023. Check your destination is on the list before you rely on it. If it isn’t, fall back to Google Maps and you’ll be fine. Find it at citymapper.com.
Rome2Rio
Rome2Rio answers one question better than anything else: how do I actually get from here to there? Type in two points and it lays out every option, train, bus, flight, ferry and drive, with rough times and prices for each. We use it constantly in the planning phase to sanity-check whether that town three hours away is reachable without a car, or whether the ferry only runs twice a week. It’s owned by Omio (since 2019), search is free, and bookings hand off to the operators. Treat the prices as ballpark figures rather than live fares. Have a look at rome2rio.com.
Rideshare: Uber, Bolt and the Local Apps
The single best rideshare tip I can give you is to find out what people actually use at your destination before you arrive, then download it and create your account while you’re still at home. Uber is not the default everywhere. When we were in Barbados, Uber had only just launched and nobody used it; everyone got around with a local app called PickUp. Across much of Europe and Africa, Bolt is more common than Uber and often cheaper. Sorting this out in advance, while you’ve got WiFi and patience, beats standing in the rain outside an airport at midnight wondering why there are no drivers anywhere near you. A quick search for “rideshare in [your destination]” before you go usually tells you which app to grab.
Planning and Organising Your Trip
TripIt
TripIt is where our trips live once they’re booked. Forward every confirmation email to the app and it builds a single day-by-day itinerary: flights, hotels, car hire and restaurant bookings, all in order, with the confirmation numbers attached. No more digging through your inbox at a check-in desk while the queue builds behind you. The free version does all of that. TripIt Pro (around $49 a year) adds real-time flight-delay alerts and alternate-flight suggestions, which pays for itself if you fly often; if you take a couple of trips a year, the free tier is plenty. See tripit.com.
Booking Flights and Accommodation
Skyscanner
Skyscanner is my first stop for flights, mostly because of how flexible the search is. You can search a whole month at once to find the cheapest days to fly, set the destination to “Everywhere” to see where’s cheapest from your home airport, and put a price alert on a route so you book at the right moment instead of refreshing the page for a week. It doesn’t sell the tickets itself, it sends you to the airline or an agent, so it’s always worth a quick check on the airline’s own site before you pay. Try skyscanner.net.
Hopper
Hopper does one clever thing well: it watches fares and tells you whether to book now or wait, based on its own price history for that route. In practice it’s quite a useful second opinion when you’re agonising over whether a fare will drop before payday. Over the years it’s grown into more of a full booking app, with hotels, cars and a stack of paid extras like price freezes bolted on, so I’d ignore the upsells and use it for the thing it does well, the prediction. Find it at hopper.com.
Booking.com
The Booking.com app is the one we open most for accommodation, from city hotels to family-run B&Bs and self-catering apartments. The map view is the part I use most: set your budget, see what’s where, and book the place that’s actually walkable to the things you came for, rather than the one that looked central until you checked the map. Free cancellation on most rooms means I’ll often reserve something refundable early and firm it up closer to the trip. Booking confirmations drop straight into the app, so they’re there when you arrive bleary-eyed at reception.
Expedia
We keep the Expedia app installed too, mainly for bundling. Booking a flight and hotel together can knock a useful amount off the total, and the app surfaces those package deals more clearly than booking the two separately ever does. If you like the idea of one app holding your flight, hotel and car hire for a trip in a single place, it’s worth having alongside Booking.com and comparing the two before you commit.
Staying Connected and Secure
Airalo
An eSIM has quietly become the first thing I sort for any international trip, and Airalo is the one we use. Instead of hunting for a local SIM card at the airport or eating roaming charges, you buy a data plan inside the app, install it before you fly, and you have working data the second you land. Plans start at a few US dollars; a week of data in Spain runs around US$7, for example, and regional plans cover whole continents. We’ve put together a full Airalo review and a wider guide to the best travel eSIMs if you want to compare providers and walk through the setup. The short version: get one, and set it up at home before you leave.
NordVPN
A VPN earns its place the moment you connect to airport or hotel WiFi, which is exactly where you’re most exposed. NordVPN is the one we’ve used for years. It encrypts your connection on networks you don’t control, and it’s handy for reaching your usual banking or streaming services that sometimes block foreign IP addresses. The plans run from a basic VPN tier up to bundles that add password management and extra security tools, so pick the level you’ll actually use rather than the biggest one. We go into more depth in our guide to using a VPN for travel.
While you’re thinking about security, turn on Find My (iPhone) or Find My Device (Android) before you leave home. It’s free, it’s already built in, and it covers the “where on earth is my phone” panic that travellers used to install separate tracking apps for.
WhatsApp is the app I’d most want set up before you leave home, and it’s easy to underrate if you’re American. It hasn’t really caught on in the US, but across most of Europe, Africa and the Middle East it’s simply how people communicate: your hotel, your guide, your taxi driver and your apartment host all expect to reach you on it. Asia is more mixed. It’s everywhere in India, but China runs on WeChat, and Japan, Korea and Thailand lean on LINE and KakaoTalk. Set up your account on home WiFi and verify your number while you still have signal on your normal SIM, and then you can message and call over data wherever you go. It quietly took over the job Skype used to do for us.
Language and Money
Google Translate
Google Translate has got us through menus, pharmacies and more than one baffling train station. Download the offline language pack before you travel and it keeps working with no signal at all. The camera mode is the killer feature: point your phone at a menu or a street sign and it translates it in place, live, on the screen. Conversation mode handles a back-and-forth with someone who doesn’t share your language, which has smoothed over plenty of taxi negotiations. It’s all free.
Google Lens
Google Lens overlaps with Translate’s camera but goes further: point it at a landmark, a plant, a product or a foreign-language sign and it tells you what you’re looking at. It’s built into the Google app and Google Photos, so there’s a pretty good chance you already have it without realising. I reach for it most with menus full of regional dishes I don’t recognise, and for working out what a building is when there’s no sign in a language I read.
XE Currency
XE Currency is the fastest way to stop doing mental arithmetic at every till. It gives you live exchange rates, stores the last ones so it still works offline, and converts between currencies instantly. I check it before haggling at a market so I actually know whether I’m arguing over fifty pence or five pounds, which changes how hard you push. Free, and worth setting your home and destination currencies before you fly. See xe.com.
Your Banking App
Your own bank’s app is one of the most useful travel apps you already own, and most people really underuse it abroad. Real-time spending alerts let you catch a dodgy transaction the moment it happens rather than a month later on a statement. You can freeze and unfreeze a card yourself the instant it goes missing, instead of making a panicked international phone call to a hold queue. Many banks now let you flag that you’re travelling so your card doesn’t get blocked on the first foreign purchase, and show your fee-free spending allowance. Set all of this up and know where the buttons are before you go.
On the Ground and Other Useful Apps
GetYourGuide
The GetYourGuide app is the one we use to book tours, day trips and skip-the-line tickets once we’ve got a feel for a place. Buying entry to a busy attraction on your phone the night before can save you an hour in a queue, and the tickets sit in the app ready to scan at the gate. It’s particularly strong for guided walks and food tours, the sort of thing where a good local guide is the whole point and turns a decent day into a memorable one.
Snapseed
Snapseed is the photo editor I still recommend to travellers, and I say that as someone who edits images professionally for a living. It’s completely free, with no watermarks, no subscription and no in-app purchases, which is almost unheard of for an editor this capable. Google let it sit dormant for years, then brought it roaring back. A complete redesign landed on iPhone in 2025, and version 4.0 reached Android in May 2026 with batch editing and a built-in camera. For quick but serious edits on a phone, selective adjustments, healing out a stray bin, proper control over a RAW file, it’s the one I open. If you want to step up to a desktop-grade workflow, we compare the options in our guides to the best photo editing software and the best Lightroom alternatives.
Dropbox and Google Drive
Cloud storage is your insurance policy on the road. Before any big trip I scan or photograph our passports, travel insurance, vaccination records and key booking confirmations and drop them into cloud storage, so a lost bag or a stolen phone doesn’t also mean lost documents. Dropbox gives you 2 GB free and Google Drive up to 15 GB, shared across Gmail, Drive and Photos. Either is plenty for a folder of documents. Whichever you use, mark the important files for offline access so you can pull them up even with no signal, which is usually exactly when you need your passport number.
The Apps That Survived, and the Ones That Didn’t
When we first wrote this guide, Skype was on it. It was how we called home for years from hostels and apartments all over the world. Microsoft retired it on 5 May 2025 and folded everyone into Teams, and that’s the thing about travel apps: the category churns constantly. Maps.me went from a favourite to ad-riddled, so the community forked it into Organic Maps. Apps get bought, change beyond recognition, or vanish.
The flip side is that the ones that are actually useful tend to stick around. Google Maps, TripIt and Google Translate have been on our phones for well over a decade and only get better. When an app on this list gets bought or shut down, we update the guide, which is the real reason a roundup like this needs a date on it rather than a “definitive forever” promise. If you’re reading an apps list with no idea when it was written, that’s your cue to be suspicious of it.
Which Apps for Which Trip
You don’t need all twenty for every trip. Here’s roughly how we prioritise, depending on where we’re going:
- For a weekend city break, Google Maps, Citymapper, an eSIM and your banking app cover almost everything, with GetYourGuide for any tickets you want to book ahead.
- For multi-country or backpacking trips, add Rome2Rio for the logistics, Organic Maps downloaded offline, WhatsApp and Skyscanner for the hops between countries.
- For a road trip, prioritise Google Maps offline, an eSIM with enough data to keep the maps running all day, and whatever local fuel or parking app the country runs on.
- For a beach or remote escape, download Organic Maps, install your eSIM, add XE Currency and save your documents for offline use before you leave. You’ll have less signal than you expect.
A Few Things Worth Doing Before You Fly
Two small habits save us grief on almost every trip. The first is to download everything while you’ve still got WiFi: offline maps for your destination, your offline translation pack, your eSIM installed and ready, and your documents saved for offline access. Signal is never as reliable as you hope, and the moment you most need a map is usually the moment you don’t have a single bar.
The second came from a reader, Scottie, who pointed us towards keeping a refillable water bottle topped up for free on the road. In the UK and a growing number of other places, the free Refill app maps cafés and shops that are happy to fill your bottle for nothing. Coverage varies a lot by country, but a refillable bottle plus a quick check for refill points saves money and a surprising amount of single-use plastic over a long trip. It’s a small thing that adds up.
Another similar app which is largely UK focused but is expanding is called Find Nearby. That one started as a free toilet finder (essential when travelling!) but has since expanded to help you find all sorts of useful free things, from water fountains to ATMs to parking.

Frequently Asked Questions
What is the best travel app?
There isn’t a single app that does everything, but if we could only install one it would be Google Maps, for offline navigation, transit directions and saved places. Close behind are an eSIM app like Airalo for mobile data and WhatsApp for staying in touch.
The right shortlist really depends on your trip, which is why we group ours by what you’re actually doing, from getting around to booking tours.
What apps should I download before international travel?
Set up the apps that need home WiFi or your usual signal to get going first: an eSIM (install it before you land), WhatsApp (verify your number while you still have signal), offline Google Maps or Organic Maps for your destination, your offline Google Translate language pack, and your banking app set to “travelling”.
Doing all of this at home, rather than in an airport arrivals hall, avoids the scramble when you’ve just landed and don’t yet have data.
Are travel apps free?
Most of the ones we recommend are completely free, including Google Maps, Organic Maps, WhatsApp, Google Translate, XE Currency and Snapseed. A few have optional paid tiers, such as TripIt Pro at around $49 a year, and a couple are paid services where the subscription is the product, like NordVPN.
An eSIM sits in the middle: the app is free, and you pay for the data plan, which can start at just a few dollars for a week away.
Do I need an eSIM, a VPN, or both?
They do different jobs, and plenty of travellers get value from both. An eSIM (we use Airalo) gives you affordable mobile data abroad without roaming fees. A VPN (we use NordVPN) encrypts your connection so you’re safer on public airport and hotel WiFi.
If you only get one, get the eSIM for connectivity, and add the VPN if you’ll be using shared networks or want to reach your home banking and streaming services. We cover each in detail in our eSIM and VPN guides.
Is Skype still available for travel?
No. Microsoft retired Skype on 5 May 2025 and moved users across to Microsoft Teams.
For staying in touch while travelling we now use WhatsApp, which is the default messaging and calling app across much of the world, with ordinary phone calls as a backup.

Scottie McCutcheon says
Thanar for this info, always pleased to here of apps that can helpo when traveling, one I have used a lot when visiting Cambodia is an the app “Refill,” it lets you know where you can refill your water bottle for free. I cant say every country has this facility but it is great when can go and top up your water bottle
Laurence Norah says
Great tip, thanks Scottie! Being able to refill a water bottle for free is definitely important when travelling 😀
Monica says
Thanks for the info! I have never heard of a VPN before. But, what I have read now, convinces me to get one. NordVPN seems a good option according to your description. I will have a little deeper research, but I think I’m going to get it :).
Laurence Norah says
Awesome 🙂 Let me know if you have any questions!
Betty Ann says
Very valuable information, it is not at all blogs that we find this, congratulations I was looking for something like that and found it here.
