Having a trip in 2025 isn't just about buying tickets and packing your bags—it's about smart travel. From starting the whole planning and booking last-minute stays to landing in a new country and navigating language barriers, travellers expect smooth experiences. That's where technology, especially eSIMs and useful travel apps, plays a big role. Whether you're hiking the Alps, lounging in Bali, or exploring Tokyo's tech scene, having the right apps can make your trip smoother, cheaper, and way more exciting.
In this guide, we'll explore the needs that almost every traveler faces in 2025 and recommend the best apps to fulfill those needs as well as some less known apps that offer some unique functionality for extra comfort or benefits.
1. Reliable Connection: The Rise of eSIM Technology
Reliable internet is the backbone of modern travel, powering navigation, communication, and real-time planning. And most of the apps that we will discuss in this blog work best with a stable connection. But once you land in a new country, you often don't have your usual mobile data, which can be very frustrating. Travelers usually choose between connecting to roaming, which often comes with high costs, limited data, or slower speeds, especially outside your plan's coverage area, or buying a local SIM card if the country's internal policy allows it. But there is one more solution that is becoming more popular and convenient nowadays - eSIM technology. Travel eSIM apps allow users to install international data plans directly on their phones. It means that instead of buying a physical SIM at the airport kiosk or hunting for risky public WiFi, you can simply download the app, choose a destination, select a data plan, and activate it before or after destination arrival. It's a fast, affordable, and reliable mobile internet alternative to roaming and a secure alternative to public WiFi. It is especially beneficial when travelling involves multiple countries with different networks. Once you try it, you won't want to travel without it.
Some well known apps in this category are Airalo, Holafly, Nomad, or Mobimatter, and this list can go on. Airalo offers affordable eSIM plans in over 200 countries. Simple setup with detailed country coverage maps and local, regional, or global data options. Holafly is perfect for data-heavy travelers. It offers unlimited data plans in selected countries and 24/7 multilingual support. Especially useful for short-term vacations. Nomad offers a clean UI, flexible pricing, and the ability to track your data usage in real-time. Mobimatter also provides a wide selection of deals, often with competitive prices.
That said, since many of these apps offer similar services, the most important factor often comes down to pricing. Limiting yourself to one eSIM provider is like flying with only one airline. For the best results, try using eSIMDB. It is the leading independent directory dedicated exclusively to finding and comparing travel eSIM brands and data plans. It's like the Google Flights of eSIMs, helping you compare multiple providers to find the best deal for your destination.
2. Smarter Booking: Flights, Hotels and More on the Go
Accommodation and transportation are the second most important issues when traveling. What are the cheapest and fastest travel options? Where can you find accommodation in the area you need? How to quickly compare prices? Where can you find reviews, and how can you quickly check and compare them? There are a large number of apps that can greatly simplify and speed up your search. In 2025, travelers are using primarily mobile apps to purchase hotel rooms and travel tickets while on the move. The key functionalities the travelers seek in such apps are aggregated travel deals, flexible cancellation options, and all-in-one travel bundles (hotel + car + activity).
For accommodation, travelers often turn to well-known Booking.com, Airbnb, and Vrbo (formerly HomeAway). Booking.com is a global leader with a wide inventory of accommodations and free cancellation on many listings. Also includes car rentals and local experiences. Airbnb offers unique accommodation options, from rooms in apartments to entire homes and exotic accommodations. Vrbo also offers a vast choice of vacation rental options for houses and apartments with convenient search and filters. The choice of the accommodation app depends on your preferences and needs. Airbnb and Vrbo are good for those looking for unique accommodation options, such as renting houses and cottages, while Booking.com offers more choices in standard hotels.
Apps like Skyscanner, Hopper, FlixBus, Rome2Rio or Omio help travelers compare and book flights and other transportation. Skyscanner and Hopper are among the most well-known flight aggregators for easy flight bookings. They allow travelers to compare prices from different airlines, find the best deals, and book tickets directly through the app. Omio allows users to search and book train, bus, and plane tickets in one app and offers a wide selection of transportation options. Flixbus is used to search for and book bus tickets across Europe. It offers affordable prices and a wide network of routes. The Rome2Rio app is a travel planning tool that helps users figure out how to get from point A to point B anywhere in the world—whether that’s across a city or across continents. It shows routes using flights, trains, buses, ferries, and even driving or walking.
And while the apps mentioned above make detailed and accurate travel planning a breeze, plans can be affected by different circumstances and not go the way it was expected. So, last-minute changes and spontaneous bookings are also common while traveling. HotelTonight is the app for last-minute accommodation searches. It shows discounted hotel rooms available for same-day bookings in a given city, helping stranded or spontaneous travelers find a place to stay quickly and affordably. So, in case some unpredictable circumstances make a traveler stuck in some place and make them look for an accommodation option, this app will be very useful. ByHours app serves tourists who need a room for a short period of time, allowing them not to overpay, rent a hotel for 3, 6, and 12 hours, and what's more, choose a convenient check-in and check-out time.
3. Planning and Staying Organized: Itinerary and Packing Assistants
Once the tickets have been purchased and the accommodation has been booked, many travelers start to feel overwhelmed by the need to keep track of multiple flight confirmations, hotel reservations, and rental car information all at once. It all becomes particularly complicated if they are not traveling alone. It's easy to lose track of confirmation emails or booking details, especially when plans change. How can you make sure you won't omit or forget anything? There are many apps that assist travellers with efficient trip planning and organization.
TripIt is the perfect solution to this problem. It can automatically organize your travel plans into a detailed itinerary. Simply forward your confirmation emails to TripIt, and it will create a master itinerary that brings together all your travel information in seconds. You can also manually add booking information if needed. It is especially useful for complex itineraries, where keeping track of the details can be a headache. Wanderlog is another app ideal for collaborative planning. It allows travelers to create and share trip itineraries, integrating maps and notes for a comprehensive planning experience.
When it comes to packing for a trip, it might often seem straightforward, but it can quickly become a source of stress. Many travelers fall into the trap of packing items for every conceivable scenario, leading to bulky luggage and potential excess baggage fees. It not only makes transportation cumbersome but also complicates finding items when needed. Conversely, some travelers underpack, forgetting crucial items like chargers, medications, or appropriate attire for specific activities. This oversight can lead to unnecessary purchases or discomfort during the trip. PackPoint is a useful travel app that helps users pack their suitcase by creating a personalized packing list based on their destination, length of stay, and planned activities. The software even takes the weather forecast into account.
4. Understanding and Speaking: Translation and Language Support
Even in an increasingly globalized world, language barriers can still pose challenges, whether you're reading a street sign, ordering food, or chatting with locals. If you know English, it will certainly help you a lot. But in some countries, especially in Asia, not many locals know it. Key functionalities the travelers need in such apps are voice-to-voice translation for real-time conversations, text and image translation (for menus, signs, documents), offline translation support, accurate speech recognition, as well as regional dialect and accent support to prevent misunderstandings.
Among the recommended apps is a well-known Google Translate. It offers text, voice, handwriting, and image translation in over 100 languages, with offline access and live conversation features. Users can point their camera at a menu or street sign, and get its translation. It is reliable and free. It also has a conversation feature, enabling two-way communication in different languages. iTranslate offers a polished interface with voice translation and dictionary features. It includes phrasebooks and supports offline use, which is ideal for travelers with limited data. DeepL Translator is known for accurate, natural translations across 33 languages, and it is ideal for nuanced communication. It's perfect for travelers needing precise translations for business or detailed interactions.
While Google Translate is great for basic phrases, it can struggle with non-Latin scripts like Korean, Japanese, or Chinese, especially when dealing with menus, handwritten signs, or regional slang. That's where apps like Papago shine. This particular app is designed specifically to understand the context and nuances of Asian languages, making them far more reliable when traveling to countries where English isn't widely spoken, like South Korea, Japan, or China. It supports real-time voice translation, image translation, offline mode, and even conversation mode similar to Google Translate, but with better contextual understanding for Asian languages.
5. Navigating Like a Local: Digital Travel Guides & Planners
Once travelers arrive at their destination, they want more than just directions. Today, they expect intelligent recommendations, offline access, and the ability to plan and adjust on the go. Digital travel guides and planners go beyond basic directions, offering curated insights and offline access. Key functionalities modern travelers are looking for in such apps are customizable itineraries, offline maps and directions, and integration with bookings and calendars.
Such well-known apps like Google Maps provide users with time-sensitive transit information, walking directions, and offline map downloads. It is a must-have for any city trip. Another useful app is Maps.Me, offering detailed maps and walking routes around the world. It has offline maps and navigation that doesn't require internet access. CityMapper is an app that specializes in public transportation. It offers detailed routes for buses, trains, subways, and other transportation in major cities around the world. The app works both online and offline, allowing travelers to easily navigate any city.
Except for standard navigation apps, there are also other apps you might not expect, but they can be very useful. Just think how many times during sightseeing in a foreign city you faced an extremely inconvenient problem - the need to use the toilet. Flush Toilet Finder is an application that will help you with this delicate question and will come in handy in an unfamiliar region. Or, if you are not using eSim, need to connect to WiFi for some reason, or do not want to spend money or your bytes for cellular communication, you can check available WiFi spots using WiFi Map. This app shows the nearest hotspots along with passwords and user comments. The app offers full map navigation to guide you to the right place and allows you to filter search results and check connection speed. Waze is another useful app for people traveling by car. It allows them to monitor the situation on the roads in real time, plot optimal routes, find out about the location of speed radars, receive information, warn other users about changing road conditions, obstacles, police, and communicate with other users on the map.
6. Exploring with Confidence: Online Guides
Traditional guided tours can be expensive due to the costs associated with tour guides and group logistics. Self-guided tours allow travelers to explore destinations at their own pace, choosing when and where to go without the constraints of a fixed schedule. This autonomy caters to individual interests and schedules, making the travel experience more personalized and enjoyable. With advancements in mobile technology, self-guided tour apps offer features like GPS navigation, offline access, and multimedia content, enhancing the user experience and making navigation in unfamiliar areas more manageable.
Lonely Planet offers expert advice, travel guides, destination information, and inspiration to help you discover, plan, and book your perfect trip. SmartGuide will transform a traveler's phone into a personal tour guide, offering self-guided audio tours created by local experts. It's particularly useful for exploring cities and attractions at your own pace. STQRY offers multimedia guides for museums, parks, and historical sites. It enhances tourists’ visit by providing detailed information, images, and audio about various points of interest.
For many modern tourists nowadays cultural immersion has become not just about seeing a city, but about feeling it like a local, gaining insights into the daily life, values, and tastes of residents. Instead of crowded landmarks, travelers are increasingly opting to explore the heart and soul of the city through unique local experiences. Spotted by Locals is the Authentic City Guides by Residents. This app offers insider tips and recommendations curated by residents from over 80 cities worldwide. Whether it's a hidden café or a lesser-known art gallery, you'll get authentic insights that typical tourist guides might miss.
7. Managing Money: Currency Conversion & Budget Tracking
Most travelers find it difficult to control and monitor their spending during trips due to unfamiliar currencies and group expenses. Many countries have their local currencies different from USD or EUR and even if you pay by a card and conversion takes place automatically, sometimes before you pay you need to understand how much that will be. Other travelers travel in groups and struggle with understanding how to divide the budget equally and avoid group conflicts. There are numerous apps that offer tools to track expenses, set spending limits, convert currencies, and split bills with friends, all in real time, making it easier to stick to a budget while traveling.
Some of the popular apps in this category are XE Currency, TravelSpend, Trabee Pocket, and Splitwise. XE Currency is a currency converter app that supports rates for most world currencies and makes it easy to calculate travel expenses. TravelSpend is designed specifically for travelers, it offers real-time expense tracking, multi-currency support, and offline access. It's particularly useful for long-term travelers and backpackers who need to manage expenses across different countries without constant internet access. Similarly, Trabee Pocket allows users to set a vacation budget and track expenses by category. It supports automatic currency conversion and provides visual representations of spending, helping travelers understand where their money goes. Splitwise is an app for sharing expenses with friends or fellow travelers. It simplifies the process of managing a shared budget and makes it transparent for all participants.
Unlike general budgeting apps, there are other apps that can target a specific financial pain point. AirHelp is a travel app that assists with flight compensation claims for delays, cancellations, or overbookings under regulations like EU261 (up to €600 per passenger). It tracks flights, checks eligibility, and handles claims, taking a 35–50% commission on successful payouts.

From skipping the SIM card line to finding a hidden local gem, these tools empower tourists to travel smarter, lighter, and happier. As you prepare for your next journey, make sure your phone is equipped with more than just a camera. With the right apps, your device becomes your translator, tour guide, and travel assistant—rolled into one.
