Best Travel Apps for Europe: Our Top Picks for 2026

Back in the day, traveling to Europe meant carrying a huge folder stuffed with printouts, a phrasebook, and a list of currency conversions. These days, things are slightly more convenient. Downloading the right apps makes you move around like a local, and it can also save you some money on top of it. 

At Going, we spend our days chasing cheap flights around the world, so we know how much smoother a European vacation feels when your phone is set up to ease your travels before you even leave home. 

However, the app stores are crowded, and a lot of what shows up is either useless abroad or quietly draining your battery and your data. We’ve rounded up a few apps we recommend, organized by the jobs you need done, like booking the flight, staying connected, getting around, translating and converting, and planning what to do once you land. The best part: Most of them are free.

Key takeaways

• Booking cheap flights: Going for flight deal alerts to Europe, Skyscanner for searching flights within Europe, and Google Flights as a powerful desktop tool for comparing carriers
• Staying connected: eSIM apps like Airalo, Saily, and Holafly for mobile data, plus WhatsApp for free calls and messages over Wifi
• Getting around: Trainline, Omio, and national rail apps for trains; Citymapper, Google Maps, Bolt, FREE NOW, and Uber for city transit and rides
• Translation and currency: Google Translate and DeepL for language, XE Currency for exchange rates
• Planning: GetYourGuide and TheFork for activities and restaurants, Rome2Rio for route options, and TripIt to keep your itinerary in one place.

Apps for booking cheap flights to Europe

The flight is almost always the biggest line item on a European trip, and getting the price right comes down to two things: knowing what a good fare looks like and being ready to book when one shows up.

Going: flight deal alerts to Europe

Going watches fares out of your home airports and sends you an alert when prices to Europe drop well below normal, including mistake fares and limited-time sales that disappear within hours. Instead of you checking prices every day, we do the watching and ping you the moment there is something worth booking.

With a Going membership, you get deals to Europe for close to domestic prices. You book the flight yourself through the airline or a reputable online travel agency (this gives you the most flexibility and control if something changes with your flight), but we hand you the deal and the dates on a plate. 

If you want to understand the timing behind all of this, our guide on the best time to book a cheap flight is a good place to start.

Google Flights: compare carriers and destinations

Google Flights does not have its own separate app. It runs in your browser on desktop or mobile web. But we want to include it in this list anyway, as it’s one of the best tools out there for catching cheap flights to Europe.

Its date grid and price calendar make it easy to see which travel days are cheapest, and the map view is great when you’re flexible about your destination and just want to see where in Europe is affordable during a certain time frame. You can also set up Google Flights price alerts to track a specific route.

Skyscanner: great for searching flights within Europe

Once you’re on the continent, hopping between cities by plane is often downright cheap, and Skyscanner helps you compare those short intra-Europe routes easily. Its “Everywhere” search lets you set a departure city and see the cheapest destinations across the map, perfect when you have a free weekend in the middle of your trip and flexibility on your side.

It covers the budget carriers, like Ryanair, easyJet, and Wizz Air, that dominate short European hops. Just read the fare rules before you book, as those cheap tickets often price bags and seat selection separately.

Apps for staying connected in Europe

Staying online in Europe without returning home to a shocking phone bill comes down to two things: getting mobile data the smart way and having a free way to call and message. 

eSIM options for Europe

Airalo: regional eSIM data across Europe

We recommend Airalo because its regional Europe plan works across dozens of countries on a single package. You buy a data plan in the app, install the eSIM by scanning a QR code, and it activates when you arrive. No physical SIM to swap, no store to find, no deposit. Plans are priced by data and duration, and you can match one to the length of your trip.

Going has partnered with Airalo to give Going Premium and Elite members 20% off an Airalo eSIM purchase. You can find it alongside our other partner discounts once you log in to your account, and it’s an easy way to knock the cost of staying connected down a notch before a big trip.

Saily: simple eSIM plans with built-in security

Saily comes from Nord Security, the team behind NordVPN. If you like the idea of one app handling both your data and a layer of privacy while you are on unfamiliar networks, Saily is a clean, no-fuss choice.

Holafly: unlimited data for heavy users

Metered plans can run out fast on a Europe trip.  Holafly offers unlimited data on its Europe plans, billed as a flat rate for a set number of days. It tends to cost more than a capped Airalo or Saily plan, so it makes the most sense for data power-users.

WhatsApp: free calls and messages over Wifi or data

WhatsApp isn’t really optional in Europe. It’s obligatory. Restaurants, tour guides, and apartment hosts might even expect to reach you there. With Whatsapp, you can send messages, photos, voice notes, and video calls over any data or Wifi connection at no cost. Download it, and add any key contacts before you fly.

Apps for getting around Europe

Europe's transit can be a pleasure if you know the right apps. Whether you're crossing borders by train or just hopping across town, your phone can save you money and a lot of guesswork. Here's what we keep on our home screens.

Trains and long-distance travel

If you plan to cross borders and connect many cities, a good rail app saves you from wrestling with a different national website for every leg. 

Trainline

This is the default for many travelers. It lets you book across many European rail and coach operators in one place, in English, with US-friendly payment.

Omio

Similar to Trainline, it adds buses and some flights into the comparison, which is handy when you’re weighing a train against a cheap flight between two cities.

National rail apps (DB Navigator, Trenitalia, SNCF Connect, Renfe)

Sometimes, booking directly with a country's own app is cheaper. Also, it usually shows the fullest range of fares and seats, plus live platform and delay info.

Quick tip: Compare a route on Trainline or Omio, then check the national app before booking to see if the direct fare beats it.

City transit and rideshare

Citymapper

It’s hard to beat Cityampper for public transit, covering metros, trams, buses, and walking routes in most major European cities, down to which subway car to board and which exit to use.

Google Maps

This is the standard navigation app for getting around a new city. The app covers solid transit directions almost everywhere, and there’s an option for offline maps, so you can download specific areas while on Wifi in case you lose signal.

Bolt

Bolt is a ride app that operates widely across Europe and is often cheaper than the alternatives, offering cars and, in many cities, scooters and bikes.

FREE NOW

This app connects you with licensed local taxis in many European capitals, useful where traditional cabs still rule.

Uber

Like in the US, Uber works in many major European cities. In some places, it dispatches regular taxis rather than the private-driver model you may be used to.

Keep Bolt and FREE NOW as backups so you’re not stranded if one has no cars nearby.

Apps for translation and currency

Google Translate

This app is a well-known battlehorse. Download the offline language packs before you go, and it translates text, speech, and even signs and menus through your camera without a data connection.

DeepL

DeepL has become our pick for those times when the wording is key (like reading a rental contract or writing a careful message to a host). Its translations tend to read more naturally (in both directions).

XE Currency

This keeps live exchange rates on your phone and works offline using the last saved rates, so you can sanity-check a price on the spot.

Apps for things to do, eat, and organize your trip

GetYourGuide

Here you can book tours, skip-the-line museum tickets, and day trips. Booking ahead will save you hours in line at places like the Colosseum and the Sagrada Família.

TheFork

This is the reservation app locals use across much of Europe, often with discounts at participating restaurants when you want a real meal over the first tourist spot you pass.

Rome2Rio

Rome2Rio shows you every reasonable way to get from A to B, comparing train, bus, flight, and drive with rough times and costs. It’s great in both the early daydreaming stage of a trip as well as the part where you actually need to get somewhere. 

TripIt

The app pulls your flight, hotel, and rental confirmations into a single tidy itinerary so nothing gets lost.

Google Maps lists

Here, you can save pins for restaurants, viewpoints, and shops into a custom list. You also have a personal map of a city you can pull up offline as you wander.

Get to Europe for less with Going

All the apps above make a European trip smoother once your trip is in motion, but the flight is still where the real savings live. With a Going membership, we watch fares from your home airports and alert you when prices to Europe drop, so you can fly for less without spending your evenings refreshing search pages.

We make sure that when a deal to Europe worth booking appears, you’re the first to know. Pair that with the apps in this guide, and you have a trip that is cheaper to get to and easier to enjoy once you land.
