The best travel apps for an international trip in 2026 are the boring ones: your airline's own app, Google Maps with the map downloaded, Google Translate with the language pack downloaded, WhatsApp, an eSIM app, and whichever ride-hailing app the country you are visiting actually runs on. That last one changes every border you cross, and it is the difference between a five minute wait and an argument at a taxi rank.
Almost everything else is optional. What follows is organised by the job you need done, with a plain note on which country needs which app, and an honest list of what to skip.
One rule before anything else: install and set up every app while you still have home wifi. Ride-hailing apps often need an SMS code to verify your number, and that code is harder to receive once your home SIM is switched off.
What are the best travel apps to have on your phone in 2026?
Nine jobs, nine slots on your home screen. If an app does not fit one of these jobs, it probably does not need to be installed.
| Job | What to install | Notes |
|---|---|---|
| Flights and boarding pass | Your airline's own app | Beats any third party tracker for gate changes and rebooking |
| Flight tracking | Flighty or Flightradar24 | Optional. App in the Air shut down in September 2024 |
| Maps | Google Maps, with the area downloaded offline | Organic Maps as a fully offline backup |
| Translation | Google Translate, language pack downloaded | Camera mode is the one you will actually use, on menus and signs |
| Getting around | Grab, Bolt, Careem, Xanh SM or DiDi | Country specific. See the table below |
| Messaging | WhatsApp, plus LINE or WeChat where required | Hotels and drivers message you here, not by email |
| Connectivity | Airalo, Nomad or Holafly | An eSIM app, installed and tested before you fly |
| Money | Your bank's app, plus Alipay or WeChat Pay for China | Turn on travel notifications before departure |
| Documents | Google Drive or your phone's files app | Passport, visa, insurance, hotel confirmations, saved offline |
Which flight apps are actually worth installing?
Install the app of the airline you are flying, and nothing else is strictly necessary. Airline apps push gate changes, delays and rebooking options before the departure boards update, and they hold your boarding pass without a signal. If you are on two carriers, install both.
For tracking, Flighty and Flightradar24 both still work well and both pull live data. Flighty is the better one if you want early delay warnings on your own flights; Flightradar24 is better if you want to watch the inbound aircraft that becomes your plane. Note that App in the Air, which used to be the default recommendation in older round-ups, closed down in September 2024, so ignore any list that still names it.
For finding fares, use Google Flights in a browser rather than an app.
How do you use maps without mobile data?
Google Maps lets you download a selected area to your phone and navigate inside it with no signal at all. Do this for each city before you leave the hotel wifi: search the city, open the menu, choose offline maps, and drag the box over the area you will actually walk. Driving directions work offline; live transit and traffic do not.
Keep Organic Maps as a backup. It is free, open source, built on OpenStreetMap data, and often better than Google for hiking trails, small islands and rural roads.
Two exceptions matter. In mainland China, Google services are blocked, so Google Maps is not a working option on a local connection. In South Korea, Korean law restricts the export of detailed mapping data, so Google Maps gives poor walking and driving directions and locals use Naver Map or KakaoMap instead.
Do translation apps work offline?
Yes, if you download the language pack first. Google Translate's offline packs cover text translation and the camera mode that reads a menu or a street sign through your phone camera. Live conversation translation is the feature most likely to need a connection, so do not rely on it in a tunnel or a temple.
Download the pack while you are still on wifi at home. Packs are a few hundred megabytes at most, and doing this at the airport gate is a common regret. Apple Translate is a reasonable alternative on iPhone and also supports downloaded languages.
Which ride-hailing app do you need in each country?
This is the single most useful thing to get right, and it is where generic lists fail. Uber is not the default in most of the world. Here is what actually works where our travellers go.
| Destination | Use this | Also worth having |
|---|---|---|
| Thailand | Grab | Bolt, which confirmed continued Thai operations in 2026 |
| Vietnam | Grab or Xanh SM | Be. Xanh SM runs an all electric fleet |
| Indonesia (Bali) | Grab | Gojek |
| Malaysia and Singapore | Grab | Singapore also has Tada and CDG Zig |
| Dubai and the UAE | Careem | Uber. S'hail for metro and bus routing |
| Kenya | Bolt | Uber, Little |
| Tanzania | Bolt | Uber in Dar es Salaam |
| China | DiDi | Available in English inside Alipay and WeChat |
| India | Uber or Ola | Rapido for two wheelers in traffic |
| Maldives | None needed | Transfers are arranged by your resort by speedboat or seaplane |
Grab covers eight Southeast Asian countries on one account, which is why it is worth setting up properly before a multi country trip through Thailand and Vietnam. Bolt has taken the same role across East Africa, so it is the app to have before a safari trip with a few days of city time in Nairobi.
Do you need an eSIM app, and does it work everywhere?
An eSIM is a data plan you install as a QR code or in app profile, with no plastic SIM and no queue at the arrivals hall. Airalo, Nomad and Holafly are the three established providers. Buy and install the profile at home, then switch it on when you land.
- Check your phone first. Most iPhones from the XS onward and most recent Samsung, Google Pixel and mid to high end Android models support eSIM, but budget handsets often do not.
- Your phone must be carrier unlocked. A handset locked to a home network will refuse the profile, and this is the most common failure point.
- Install before you fly, activate after you land. Installing needs wifi. Most plans start counting from first connection, not from purchase.
- Keep your home SIM active for calls. Use the eSIM for data and leave your normal number on for bank OTPs and airline SMS.
- A local SIM can still win on long stays. For a trip of several weeks in one country, a local operator's SIM usually gives more data. For a week or two across borders, the eSIM is easier.
Which apps matter specifically in China?
China needs its own set, and this is where most travel app lists are out of date. Cash is accepted by law but rarely convenient, and daily life runs on two apps.
Foreign travellers can now bind an international Visa, Mastercard or Amex directly inside Alipay and WeChat Pay, without a Chinese bank account. Setup requires your passport and a selfie for identity verification, and there are per transaction and annual caps that rise if you complete the fuller verification. The older Tour Pass or TourCard prepaid workaround still exists inside Alipay but has been made largely redundant by direct card binding. Set this up at home, because verification can take a little time.
Alipay and WeChat also act as super apps: DiDi rides, metro QR tickets, train bookings and translation all sit inside them in English. For maps, use Amap or Baidu Maps, since Google Maps is blocked and inaccurate there. Some travel eSIMs route your data through gateways outside mainland China, which lets Google, WhatsApp and Instagram work without a VPN, but confirm that with the provider before you buy rather than assuming it. If you are still weighing the trip up, our guide on whether China is safe to travel covers the practical side.
Which travel apps are not worth it?
- Paid offline map apps. Google Maps offline plus Organic Maps covers everything they do, at no cost.
- Currency converter apps. Google, your phone's built in search, and your bank app already convert. An extra app is one more thing carrying ads.
- Itinerary aggregators that read your email. They ask for inbox access and mostly reproduce what your airline app and a note on your phone already show.
- Packing list apps. A note or a checklist in your phone's own notes app does the same job and does not need an account.
- Generic "travel safety" apps. Most repackage public advisories. Read your government's travel advice page directly and save your embassy number in your contacts instead.
- Region locked payment apps you cannot register for. Several country specific wallets require a local bank account or national ID and will simply reject a foreign traveller.
What should you set up before you leave home?
- Download the offline map for every city on the trip, not just the first one.
- Download the translation language pack for each country you will pass through.
- Verify each ride-hailing app by SMS while your home number is still receiving messages normally.
- Save documents offline. Passport photo page, visa, insurance policy, hotel confirmations and your return ticket, all in a folder marked available offline.
- Tell your bank you are travelling and enable notifications, so a foreign transaction is not blocked at a hotel check in.
- Turn on WhatsApp two step verification before you change SIM behaviour, and note down your account backup details.
- Carry a power bank. Every app on this list is useless on a dead phone, and airlines require power banks in your cabin bag, never in the hold.
Getting the app set right is a small job that removes most of the friction from a trip. If you would like the country specific apps sorted for you along with visas, transfers and hotels, our team plans this into every itinerary, including trips to Dubai and across China.
Frequently asked questions
What are the best travel apps for an international trip?
Your airline's own app, Google Maps with offline maps downloaded, Google Translate with the language pack downloaded, WhatsApp, an eSIM app such as Airalo or Nomad, and the local ride-hailing app for your destination. Those six cover almost every situation. Everything beyond them is a preference, not a requirement.
Does Uber work in Southeast Asia?
Uber does not operate in most of Southeast Asia. Grab is the dominant app across Singapore, Malaysia, Indonesia, Thailand, Vietnam, the Philippines, Cambodia and Myanmar, and one Grab account works in all of them. In Vietnam, Xanh SM and Be are strong alternatives to Grab.
Can I use Google Maps in China?
No. Google services are blocked in mainland China and Google Maps data there is inaccurate, so it is not a reliable option on a local connection. Use Amap or Baidu Maps instead, or use a travel eSIM that routes data outside mainland China. Both Alipay and WeChat also have built in navigation and ride booking.
Do I need an eSIM or a local SIM card?
An eSIM is easier for short trips and multi country routes because you install it at home and switch it on when you land. A local SIM usually gives more data for a longer stay in a single country. Your phone must be eSIM capable and carrier unlocked, so check both before buying.
Do travel apps work without internet?
Some do, if you prepare them. Google Maps navigates offline once you download the area, Google Translate translates text and camera images offline once you download the language pack, and airline boarding passes stay in your wallet. Ride-hailing, live transit and payment apps all need a connection.
Which payment app do I need in China as a foreign visitor?
Alipay or WeChat Pay, with an international Visa, Mastercard or Amex bound directly inside the app. This no longer requires a Chinese bank account, but it does require passport based identity verification, and there are per transaction and annual caps. Set it up before you travel rather than on arrival.
Is Flighty or Flightradar24 better for tracking my flight?
Flighty is better for tracking your own itinerary, since it warns about delays early and handles connections well. Flightradar24 is better for watching live aircraft, including the inbound plane that becomes your flight. App in the Air, often still listed in older articles, shut down in September 2024.
