The Best Travel Planning Apps & Websites (And How to Use Them Smarter)

Travel planning has become so much easier thanks to the number of helpful travel apps and websites available to us these days. Everything from finding cheap flights and organizing itineraries, to discovering hidden gems and navigating new destinations, can be done with the help of an app — and knowing which ones are the right tools can save you time, money, and a whole lot of stress.

As someone who previously worked as a full-time corporate travel agent and now plans trips regularly as a travel blogger, I’ve tested a lot of travel tools over the years. While many of these travel apps and websites weren’t necessarily used in the corporate travel world, several are tools I personally relied on long before working in the industry — and still use today for planning my own trips.

Over time, I’ve also learned that it’s not just which travel apps you use, but how you use them. Some platforms are amazing for researching flights, hotels, and trip ideas, while others are better avoided for actually booking travel directly.

Why I Use Travel Apps Primarily as Research Tools

Planning a trip today looks a lot different than it did even a decade ago. Instead of printing directions, carrying around paper confirmations, or bouncing between dozens of browser tabs (actually, I still do this…), travel apps and travel planning websites now make it possible to organize nearly every part of your trip directly from your phone or laptop. With these tools, things like comparing flights, keeping an eye on hotel prices, saving restaurant recommendations, and creating itineraries, it’s easier to simplify the entire travel planning process.

Over the years, I’ve also learned that many travel apps are best used as planning and research tools rather than as booking platforms. I personally will always book flights directly with the airline, and hotels/accommodation directly whenever possible, instead of through a third-party booking site.

After working in corporate travel, I learned pretty quickly how much easier it can be to manage delays, cancellations, or itinerary changes when booking directly through an airline or hotel. The nuance here, is that corporate travel agencies and travel management companies (TMCs) typically operate a bit differently, often with more direct airline and hotel relationships than the customer support systems behind many consumer booking platforms. So, unless you’re booking your trip through a TMC (and if you’re here, I’m guessing you probably aren’t), it’s usually best to book your flights and hotels directly.

That said, there are still a few exceptions (like Airbnb and Hostelworld) where the platform itself is part of the booking experience and works a bit differently. There are also some travel apps that I do book directly through and have personally had positive experiences with. I’ll point out which platforms I recommend booking directly with throughout the guide below.

Best Travel Apps for Finding Flights

Skyscanner & Kiwi — Best for Finding Cheap Flights

Skyscanner and Kiwi.com are two of my favorite travel planning websites for researching flight options and comparing airfare across multiple airlines at once. Both platforms are especially useful if your travel dates are flexible or you’re still deciding where you want to go, since they make it easy to compare pricing across destinations and date ranges quickly.

I particularly like using these tools during the early trip planning phase to get a general sense of flight costs, route options, and potential travel deals. Sometimes Kiwi can also surface more creative or budget-friendly flight combinations that may not immediately appear through traditional airline searches.

You’ll notice I didn’t mention Google Flights with the other two — that’s intentional. From my experience, the platform has not been as user-friendly and has more inaccuracies (such as with flight pricing). So I usually just skip using this one.

Thrifty Traveler — Best for Flight Deal Alerts

Thrifty Traveler is one of my favorite resources for finding cheap flight deals and airfare sales, especially for international travel. The platform primarily operates through email alerts that notify subscribers about discounted fares, limited-time sales, and unusually good flight deals departing from specific airports.

Thrifty Traveler offers both free and premium membership options, with the paid version unlocking more frequent domestic and international deal alerts, premium cabin deals, and points-and-miles opportunities. If you’re flexible with your travel dates or destination, the membership can be a great way to discover trips you may not have otherwise considered.

Honestly, several of my past international trips happened simply because I found a great flight deal first and built the trip around it afterward. Since airfare is often one of the biggest travel expenses, finding a cheap flight can completely change what destinations suddenly become realistic within your budget. If you have flexibility in your travel dates or destination, email alert services like this one can be incredibly helpful while planning future trips.

Going — Best for Curated Cheap Flight Deals

Going (formerly Scott’s Cheap Flights) is another excellent tool for finding discounted airfare and international flight deals. Similar to Thrifty Traveler, Going focuses more on surfacing exceptional flight prices and mistake fares rather than searching for one specific route manually.

This platform also offers both free and paid membership tiers that send curated flight deal alerts based on your preferred departure airports. Paid memberships include access to more international deals, premium cabin alerts, mistake fares, and additional customization features. If you’re flexible about where or when you travel, Going can be an incredibly useful tool for finding trips that may not have originally been on your radar.

Best Travel Apps for Hotels & Accommodations

Airbnb — Best for Unique Stays & Longer Trips

Airbnb is one of my favorite platforms for finding unique stays, apartments, cabins, and longer-term accommodations while traveling. Airbnb is especially ideal for group trips, for when you’re traveling with a pet, and for finding places where having extra space, a kitchen, or laundry access are a higher priority for you.

Unlike many third-party hotel booking platforms, Airbnb functions a bit differently since the platform itself is part of the booking experience. This is one of the few travel apps where I regularly book directly through the platform and personally haven’t had issues doing so. That said, I still recommend reading reviews carefully, paying attention to cancellation policies, and double-checking cleaning fees before booking.

Depending on the destination, Airbnb can sometimes be significantly cheaper than hotels — while in other places, hotels may actually end up being the better overall value once fees are included. I usually compare both options before deciding what makes the most sense for the specific trip.

Hostelworld — Best for Budget & Solo Travelers

Hostelworld is actually where I’ll first start my accommodation search — it’s one of the best travel planning websites for finding hostels, especially if you’re looking for something solo traveler- or budget-friendly. The platform makes it easy to compare hostel locations, amenities, ratings, and social atmosphere before booking, which can make a huge difference depending on the type of travel experience you’re looking for.

Hostels are frequently some of the most affordable accommodation options available, and many also offer private rooms that can still cost significantly less than nearby hotels. That said, not all hostels are the same, so it’s definitely worth reading through reviews carefully to find an option that matches the type of experience you’re actually looking for. Some hostels are very social and party-focused, while others are quieter, more relaxed, and feel almost closer to boutique hotels.

I’ve personally used Hostelworld while traveling internationally and have only had positive experiences booking directly through the platform. Similar to Airbnb, the app itself is more integrated into the booking experience than a traditional third-party hotel aggregator. I also find the guest reviews especially helpful since many travelers leave detailed feedback about cleanliness, safety, social atmosphere, and overall hostel experience.

Booking.com — Best for Researching Hotels

Booking.com is one of the travel planning websites I use when researching hotels, apartments, and other accommodations. I especially like how easy it is to filter by budget, neighborhood, guest ratings, amenities, cancellation policies, and property type all in one place. For international travel in particular, it often has a huge inventory of accommodations that can be helpful for comparing options quickly.

I personally use Booking.com only as a hotel research tool rather than a booking platform. I use this in conjunction with Google Maps to get a sense of where hotel options are located. Once I narrow down the hotel I want, I’ll usually compare rates directly on the hotel’s website before booking. In many cases, the pricing is similar, and booking directly can make changes, cancellations, upgrades, or customer service issues much easier to manage if something goes wrong during your trip.

That said, I have booked directly through Booking.com before and haven’t personally had the best experiences with customer service when I needed to make a change or cancellation. For that reason alone, I generally won’t book through this platform and prefer having a direct line of communication with the hotel.

Best Travel Planning Apps for Building Your Itinerary

Pinterest — Best for Travel Inspiration & Visual Trip Planning

Pinterest is one of my favorite travel planning tools for gathering destination inspiration, saving itinerary ideas, and organizing trip research visually. I’ll often use Pinterest during the early planning stages of a trip to find things like hidden gems, photo spots, travel guides, restaurant recommendations, packing inspiration, and sample itineraries for a destination.

One thing I especially like about Pinterest is how easy it is to organize ideas into separate travel boards for future trips. Over time, it almost becomes a visual mood board and planning hub for different destinations. I also find it helpful for discovering smaller blogs, local recommendations, and more niche travel experiences that don’t always appear immediately through Google searches.

And of course, you’re always welcome to pin any of the travel guides from my site to save for later or browse through my own Pinterest boards if you’re looking for travel inspiration. I have boards organized by destination, trip type, and bucket-list ideas if you ever want a glimpse into what’s currently on my own travel wish list.

That said, I do think it’s important to fact-check and cross-reference information you find on Pinterest, since not every itinerary or travel tip circulating on the platform is necessarily current or accurate. But it’s a great place to start getting travel ideas and saving them for future reference.

Instagram — Best for Visual Research on Restaurants, Hotels, and Local Businesses

Instagram has honestly become one of the biggest travel planning tools of the past decade. When I’m not sharing my own travel content, I’m frequently using Instagram to research destinations, save travel inspiration, and get a more visual sense of what a place actually looks like beyond curated tourism photos. It can be especially helpful for finding restaurants, cafés, hikes, viewpoints, beaches, hotels, and activities through location tags, creator recommendations, and recent posts.

Instagram has also undeniably shaped modern travel photography culture — to the point where #Instagrammable has basically become its own category of travel aesthetic. Whether that’s a good thing or not probably depends on who you ask, but there’s no denying the platform has influenced everything from hotel design and café interiors to destination popularity and photography trends over the last decade.

I use Instagram less for finding nature spots (because nature is always pretty, and usually photographs well regardless) and more for researching the ambiance and aesthetic of hotels, cafés, restaurants, and local businesses of a destination before adding them to my itinerary.

And if you ever want to follow along on my own adventures, you can find me on Instagram here.

Google Maps — Best for Saving Places & Building Custom Maps

Google Maps is probably the travel app I use more than any other while planning a trip. Long before I book flights or hotels, I’m already saving restaurants, viewpoints, coffee shops, beaches, hikes, and attractions directly into custom map folders. It’s one of the easiest ways to visually organize your itinerary and get a better understanding of where things are located before you arrive.

I also love using Google Maps to build rough travel itineraries and avoid accidentally booking accommodations too far away from the places I actually want to visit. I also frequently use Google Maps while traveling internationally for walking directions, train routes, and navigating public transport systems in larger cities. You can even download offline maps ahead of time, which is incredibly helpful for international travel or road trips through areas with spotty service or no internet connection.

Rome2Rio — Best for Transportation Planning

Rome2Rio is one of the most underrated travel planning websites, especially for international trips or multi-city itineraries where figuring out transportation logistics can quickly become overwhelming. This is actually one of the tools I used even in the corporate world. Instead of opening ten different tabs trying to compare trains, ferries, buses, flights, rental cars, and public transportation routes separately, Rome2Rio pulls everything together into one place. It’s the easiest way to figure out how to get from A to B.

I especially like using it during the early planning stages of a trip to get a realistic sense of how long it actually takes to get between destinations, what transportation options are available, and whether a route is practical before finalizing an itinerary. It’s also incredibly helpful for Europe trips, island hopping, and destinations where public transport networks are more heavily used.

I don’t book directly through Rome2Rio itself, but still find the platform to be incredibly useful as a research and logistics tool for mapping out transportation plans more efficiently.

Best Travel Apps for International Travel

XE Currency — Best Currency Converter for International Travel

XE Currency Converter is one of the most useful travel apps to have downloaded before any international trip. The app makes it easy to quickly convert currencies and keep track of exchange rates while traveling abroad, which becomes especially helpful when you’re trying to mentally calculate prices in an unfamiliar currency.

You can save multiple currencies at once and also access recent exchange rates offline, which is helpful if you don’t always have reliable cell service while traveling.

In recent years, the app has also included options for sending and receiving international money transfers as well. Although I personally only ever use it as a tool to convert local currency.

Duolingo — Best for Learning Basic Travel Phrases

Duolingo is one of the easiest and most approachable travel apps for learning a few basic phrases before visiting another country. While it’s obviously not going to make you fluent overnight, even learning a few basic phrases can be helpful when navigating restaurants, public transport, or asking for directions while traveling abroad.

I also think making an effort to learn at least a little bit of the local language helps create a more respectful and immersive travel experience overall. Even small interactions — like ordering food, saying thank you, or greeting someone in their native language — can make traveling feel much more personal and connected.

One thing I especially like about Duolingo is that the lessons are short, simple, and easy to fit into your daily routine before a trip. If you’re starting from scratch with a new language, it makes the learning process feel much less intimidating and more approachable for casual travelers.

Google Translate — Best for Navigating Language Barriers

Google Translate is one of the most useful travel apps to have downloaded before any international trip. Even if you learn a few basic phrases ahead of time, there will almost always be moments where translation tools come in handy while traveling abroad.

One of my favorite features is the camera translation tool, which lets you point your phone at menus, signs, grocery labels, train schedules, and other text for quick translations in real time. You can also download languages offline ahead of your trip, which is incredibly helpful if you won’t always have reliable cell service or Wi-Fi access.

Mobile Passport Control — Best for Re-Entering the U.S. Faster

If you’re traveling internationally from the U.S., Mobile Passport Control is one of those travel apps that more people should know about (I only learned about it myself in recent years). The app allows eligible travelers returning to the United States to submit passport and customs information directly through their phone before arriving at customs, which can help speed up the re-entry process at participating airports.

After long international travel days, anything that potentially shortens the customs line feels worth it. It’s free to use and can make arriving back in the U.S. feel slightly less chaotic — especially after a long-haul flight.

WhatsApp — Best for International Communication

WhatsApp is one of the most essential travel apps for international communication. In many countries, it’s the primary way hotels, tour companies, drivers, restaurants, and even local businesses communicate with travelers.

I use WhatsApp constantly while traveling internationally for messaging accommodations, coordinating airport transfers, sharing locations, making tour arrangements, and staying in touch with friends or family over Wi-Fi without relying heavily on international texting plans. If you don’t already have it downloaded, I highly recommend setting it up before leaving for your trip.

Best Travel Apps for Outdoor Adventures

AllTrails — Best for Outdoor Adventures & Hiking

AllTrails is one of the best travel apps to have downloaded if your trips involve hiking, national parks, or outdoor adventures. The app includes trail maps, difficulty ratings, elevation gain, recent trail conditions, photos, and reviews from other hikers, which can be incredibly helpful while researching trails before heading out.

Living in Colorado, I use AllTrails frequently for both local hikes and travel planning. I especially like being able to read recent trail reviews before visiting, since conditions can change pretty quickly depending on weather, season, snowpack, or maintenance closures. The offline map feature is also extremely useful when hiking in areas with limited cell service or internet access.

That said, I still recommend doing a little extra research beyond just relying on one app alone — especially for longer hikes, backcountry hiking trails, or more challenging outdoor adventures. Trail conditions, weather, altitude, and difficulty can sometimes feel very different in person than they appear online.

COTREX — Best for Hiking in Colorado

If you’re a fellow Colorado local or planning to visit Colorado, COTREX (Colorado Trail Explorer) is one of the best outdoor adventure apps specifically for hiking and exploring trails throughout the state. The app was created through a partnership between Colorado Parks & Wildlife and the Colorado Tourism Office, and it includes detailed trail maps, closures, conditions, accessibility information, and route planning tools for thousands of trails across Colorado.

I’ve found COTREX especially helpful for discovering new hiking trails, checking trail access information, and researching routes before heading out. The app also integrates official land management data, which can sometimes make trail information feel more reliable and up-to-date than other hiking apps. If you’re planning a Colorado hiking trip or spending time exploring the state’s outdoor scenery, this is definitely one of those apps worth downloading ahead of time.

What About Travel Apps for Packing?

Honestly, I’ve never used any dedicated packing apps for any of my travels. Between Notes app checklists and travel experience, I essentially created my own packing list template to start with, and will add to that depending on what type of trip I’m taking. It’s a system that works pretty well for me.

That said, I know some of you may prefer a more structured resource for packing and checklists to stay organized and avoid overpacking.

I have some packing list guides I’ve curated on my site that you can browse that may be relevant to your upcoming trip — these are linked below.

For more packing resources, Pinterest is actually a great place to find specific checklists and might be worth browsing through as well.

Final Thoughts on the Best Travel Apps & Websites

At the end of the day, the best travel apps are the ones that help simplify your travel plans and make the overall experience feel less stressful and more enjoyable. Whether you’re researching flights, comparing hotels, mapping out an itinerary, navigating public transport, finding hiking trails, or saving destination inspiration for later, the right travel planning tools can make a huge difference before and during your trip.

And of course, everyone plans trips a little differently. Maybe you love detailed itineraries and spreadsheets, or maybe you prefer a more spontaneous approach. Regardless of how you travel, I hope you found some value in any of these travel tools.
