I used to travel with a printed itinerary folded into my jacket pocket. This was not that long ago. I'd write down hotel addresses by hand, screenshot maps before losing WiFi, and spend twenty minutes at currency exchange counters doing mental math I was never confident about. At some point I stopped doing all of that, not because I became a more relaxed traveller but because the right apps eliminated most of the friction that made those things necessary.
I'm Shubham, and I've tested a lot of travel apps over the years — some because they came recommended, some out of desperation at 11pm in an unfamiliar city. This list is what I actually use and why. Not every app that exists, not a padded list of fifty things to download. Just the ones that have genuinely changed how I travel.
Before We Start: The Rule I Follow
I only keep travel apps that solve a specific problem I've actually had. The app stores are full of travel tools that sound useful in theory and collect dust in practice. For each app here I'll tell you the specific situation where it earns its place.
Flights and Trip Planning
Google Flights
The best flight search tool available, and it's free. The reason it beats most aggregators is the flexibility view — you can search an entire month and see prices across every date at once, which is the fastest way to find the cheapest window to travel. The price tracking feature sends alerts when fares on a specific route change.
I use it at the start of every international trip planning process before touching any other booking platform. It doesn't always have the cheapest final price — sometimes booking directly with the airline is slightly better — but for finding when to fly, nothing beats it.
Shubham's Take: On a trip to Vietnam last year I used the calendar view to spot that flying out on a Wednesday instead of Friday saved ₹8,400 on a round trip. That's a few nights of accommodation recovered from one five-minute check.
Skyscanner
Where Google Flights sometimes falls short is on budget airline coverage and certain regional routes. Skyscanner fills that gap. The "everywhere" search feature — where you enter your departure city and leave the destination blank — is the best tool I've found for spontaneous trip decisions. Type your city, select "everywhere," pick a month, and it shows you the cheapest destinations available from where you are.
I've planned two trips entirely from that screen — not because I had no preference, but because the price difference between my vague shortlist and a Skyscanner suggestion was significant enough to shift my thinking.
TripIt
You forward your booking confirmation emails to TripIt and it builds a master itinerary automatically — flights, hotels, car rentals, restaurant reservations. The result is a single chronological document covering your entire trip that lives on your phone and syncs offline.
The reason this matters: when you're in transit, tired, and trying to remember which terminal your connecting flight leaves from, having everything in one place without hunting through emails is worth a lot. The free version handles the basics well. The paid version adds real-time flight alerts and seat tracking, which is useful for frequent travellers.
Navigation and Maps
Google Maps (Downloaded Offline)
This is obvious, but the offline download feature is not used enough. Before any trip, open Google Maps, search the city or region, tap the three-dot menu, and download the area for offline use. The downloaded map covers navigation, search, and directions without any data connection.
I've relied on this in Spiti Valley with zero mobile signal, in rural Japan where my data SIM wasn't working, and in Marrakech's medina where WiFi was inconsistent. It has not failed me once.
Shubham's Take: Download the map the night before at your hotel or hostel on good WiFi, not at the airport on a slow connection. Large city maps can be several hundred megabytes.
Maps.me
For areas where Google Maps has poor detail — rural regions, hiking trails, smaller towns in developing countries — Maps.me often has better coverage. It's built on OpenStreetMap data, which is community-maintained and frequently more detailed than Google in off-the-beaten-path areas.
I use it specifically for trekking and hiking. In Sikkim's North district and on trails around Dharamshala, Maps.me had trail detail that Google Maps simply didn't have. Download it before heading anywhere where trail navigation matters.
Rome2rio
The answer to "how do I get from here to there" when the options are unclear. Enter any two points in the world and Rome2rio shows every transport option — flights, trains, buses, ferries, rideshares — with approximate times and costs for each. It doesn't always book the tickets but it tells you what exists, which is the first problem to solve.
I use it when I'm planning overland routes in new regions where I don't know what transport infrastructure looks like. It's the app that told me a ferry existed between two Indonesian islands I was trying to connect, saving me a significant backtrack.
Accommodation
Booking.com
My primary accommodation booking app for most destinations. The filter system is genuinely useful — filter by review score, free cancellation, breakfast included, distance from city centre — and the review volume means the ratings are meaningful. A property with a 8.5 score and 600 reviews is reliable information. A property with a 9.2 score and 11 reviews tells you much less.
Free cancellation bookings are worth choosing whenever the price difference is small. Plans change, and the flexibility has saved me accommodation costs more than once when a travel day shifted.
Hostelworld
For hostel-specific searches, Hostelworld has better depth than Booking.com. The reviews here are left by the hostel's actual target demographic — backpackers and budget travellers — which means the feedback is relevant to what you're actually evaluating. A hostel with great reviews on Hostelworld from people who care about the social atmosphere and clean dorms is more useful information than a star rating from a mixed audience.
Airbnb
Most useful for longer stays and destinations where having a kitchen saves meaningful money. I use it less for short trips and more when I'm spending a week or more somewhere and want to live in a neighbourhood rather than a hotel zone.
The monthly discount feature is underused. Stays of 28 nights or more often get 20–40% discounts, which brings Airbnb apartments below hotel rates in many cities.
Transport and Getting Around
Uber / Ola
Having both installed before international trips matters because coverage varies. Uber works in most major global cities. Ola has better coverage in certain South Asian and Australian cities. The key advantage both have over street taxis is price transparency before you get in — you know the cost, the route, and the driver's rating before confirming.
Shubham's Take: In cities I don't know, I always check the rideshare app price before negotiating with a street taxi. It gives me a real reference point. More often than not, the rideshare is cheaper and the experience is less confrontational.
Grab
Essential for Southeast Asia. Grab covers taxis, motorbike rides, food delivery, and payments across Thailand, Vietnam, Indonesia, Malaysia, Singapore, Cambodia, and the Philippines. It works better than Uber in this region and is the default transport app for most travellers moving through Southeast Asia.
Install it before your first day in Bangkok, Ho Chi Minh City, or Bali and it will earn its place within the first hour.
Rapido
For Indian travel specifically, Rapido's bike taxi service is the fastest and cheapest way to move short distances in traffic-heavy Indian cities. In Bangalore, Hyderabad, and Pune especially, where road congestion is significant, a bike taxi cuts travel time meaningfully compared to a car. The app also does auto-rickshaw bookings now in many cities.
IRCTC Rail Connect
Non-negotiable for anyone travelling within India by train. Book train tickets, check PNR status, manage bookings — all in one app. The interface has improved considerably over the last few years and the booking process, while occasionally frustrating during Tatkal windows, works reliably.
Book at least three weeks in advance for popular routes in sleeper or AC classes. Waiting list tickets on long routes usually don't confirm if you're below position 20 or so in peak season.
Translation and Communication
Google Translate
The camera translation feature — point your camera at text and see it translated in real time on screen — is one of the most practically useful things a smartphone can do while travelling. Restaurant menus in Japanese, street signs in Arabic, product labels in Thai — the accuracy is imperfect but good enough to be genuinely helpful in most situations.
Download the language packs for your destination before you go so the feature works offline. In Japan and East Asia especially, this feature earns its keep daily.
Duolingo
Not for becoming fluent — that's a separate project. Duolingo before a trip is useful for learning fifty to a hundred words and basic phrases in the local language. Enough to greet people properly, say thank you, ask for the bill, apologise for your inability to speak the language more. In Japan, Thailand, and Eastern Europe this kind of minimal effort is noticed and appreciated out of proportion to how little it costs you.
I typically do two to three weeks of Duolingo in a destination's language before departing. It doesn't make me conversational. It makes interactions warmer.
Money and Finance
Wise (formerly TransferWise)
The best way to hold and spend foreign currency without getting punished by bank fees. The Wise multi-currency account lets you hold balances in multiple currencies and spend abroad at the real mid-market exchange rate with minimal fees. The debit card works at ATMs and shops globally.
For Indian travellers doing international trips regularly, Wise is more practical than most Indian bank forex cards and significantly cheaper than using a standard debit card internationally.
XE Currency
A clean, fast currency converter with offline functionality. I use it specifically for quick mental math at markets and when negotiating prices in destinations where the local currency involves large numbers — Indonesian rupiah, Vietnamese dong, Japanese yen. Knowing that ¥1,000 is approximately ₹560 is fast enough to do mentally, but when you're looking at a ¥48,000 hotel rate and want to sanity-check it in three seconds, XE does it cleanly.
Splitwise
For group travel, Splitwise removes the one source of friction that ruins more trips than bad weather: shared expenses. Log who paid what, split unevenly where appropriate, and settle up at the end. The running balance means everyone always knows where they stand without awkward mid-trip conversations about money.
Shubham's Take: I've done group trips both with and without Splitwise. With Splitwise, the money conversation happens once at the end and takes ten minutes. Without it, it's a recurring low-grade tension throughout. Install it on day one of any group trip.
Health, Safety and Documents
TripCase / Google Drive
Storing copies of important documents — passport, visa, insurance, hotel confirmations — in cloud storage means they're accessible even if your phone changes or gets lost. I keep a Google Drive folder called "travel docs" with scanned copies of everything before every international trip. It has never been necessary. I am very grateful for that and I'm not stopping.
iSOS / TravelSafe
For serious travellers and anyone going to destinations with political instability or significant health risks, the International SOS app provides destination-specific safety alerts, hospital locations, and emergency contact numbers. Most people won't need it most of the time. The value is entirely in the edge cases.
Medisafe
If you take regular medication, Medisafe tracks your doses and sends reminders. Useful specifically when crossing time zones changes your medication schedule — the app lets you adjust timing and will flag if you've missed a dose. Simple, genuinely useful for anyone on a regular prescription.
Entertainment and Downtime
Spotify (Downloaded Playlists)
Long flights, overnight buses, train journeys through mountains — downloaded playlists are the difference between a journey that feels like a waste of time and one that feels like part of the trip. Download before you lose WiFi access. The obvious point that somehow often gets missed until you're already airborne.
Kindle App
One app, hundreds of books, no weight added to your bag. I read more while travelling than at any other time — long transit legs, slow evenings in guesthouses, waiting at airports. Having a library on your phone with no physical space cost is the best reading upgrade available to travellers.
The Apps I Deleted
Worth saying: I've tried and removed a lot of apps that didn't earn their place.
TripAdvisor has too many fake or incentivised reviews now to be the reliable tool it once was — I use Google Maps reviews and Booking.com reviews instead. Many dedicated travel wallet apps are solved better by Wise or a good bank card. City-specific apps that only work in one destination are rarely worth the storage.
The test I now apply before downloading anything travel-related: does this solve a specific problem I've had, or does it only solve a problem I'm imagining? Most apps fail that test.
The Setup I Actually Use
Before any international trip, here's the specific sequence I follow:
Download Google Maps offline for every destination. Load Wise card with local currency. Screenshot confirmation emails into TripIt. Install Grab if going to Southeast Asia. Check Google Translate has offline language packs for the destination. Download two or three books on Kindle. That's it. Everything else exists already on the phone and works without preparation.
The goal is not to have every app. The goal is to have no moment in the trip where the solution to a simple problem is "I don't have the right tool."
The best travel apps are the ones you forget you're using because they've made something that used to be a problem feel effortless. Google Flights made flight searching effortless. Offline Maps made navigation effortless. Splitwise made group money effortless. Grab made transport in Southeast Asia effortless.
None of these are magic. They're just tools that solve real problems cleanly. Download what you need for your next trip, delete what you're not using, and then stop thinking about apps and start thinking about where you're going.
