Every travel app list is thirty apps long, which is a useful sign that the person writing it does not travel much. In practice you use about six, and the rest sit there taking up space until you delete them in an airport. Here is the short list, and more usefully, the reasoning for what earns a slot.

The test an app has to pass

It must do something you genuinely cannot do in a browser, and it must work when your connection does not. That second criterion eliminates most of them immediately, because the moments you need an app most — landing somewhere new, standing outside a station, phone on 12% — are exactly the moments you have no data.

1. Offline maps

The single most valuable thing on the phone. Download the city before you fly, and the whole thing works with the radios off: search, walking directions, saved pins, transit lines.

The habit that matters more than the app: download the map the night before, not on arrival. Doing it over airport wifi while jet-lagged is how it does not get done.

2. A translation app with the offline pack installed

Not for conversation — for the camera. Pointing a phone at a menu, a station board or a medicine packet and having it rendered in English is genuinely transformative in a country whose script you cannot read.

Again, the offline language pack is the whole point. Download it before you go.

THE RULE FOR ALL SIX

If it needs a connection to be useful, it is a website, not an app. The ones that earn a home-screen slot are the ones that work on a dead phone in a dead zone.

3. Your airline’s own app

Boarding pass in the wallet, gate changes pushed to your phone before they hit the boards, and — the real reason — self-service rebooking when something cancels. While two hundred people queue at the desk, the app frequently lets you rebook in ninety seconds. That single feature has saved more nights than every other app on this list combined.

4. A flight search tool with price alerts

Google Flights does ninety percent of the work: a calendar grid showing a whole month at once, an Explore map for when your dates are firm but the destination is not, and price tracking that does your waiting for you. Skyscanner is the second opinion, because different engines carry different airlines and budget carriers routinely appear on one and not the other.

The feature almost nobody uses is the price alert itself. Set it the moment you know your route, then stop refreshing.

5. Whatever the local transport or ride app is

This is the one that changes by country and it is worth thirty seconds of research before you land. In much of Asia the dominant app is not the one you use at home, and having the right one installed before you walk out of arrivals is the difference between a fixed fare and a negotiation at the moment of maximum disorientation.

6. A password manager

Unglamorous and it belongs here. You will be logging into things on unfamiliar networks, and if your phone is lost or stolen, everything you need to lock down lives behind one password you can access from any device.

What does not earn a slot

Currency converters. Your phone does maths. Learn the one number that matters — roughly what 100 of the local currency is worth — and you will not open an app again.

Packing list apps. A note works. A printed checklist works better.

Itinerary aggregators. Pleasant when they work, and they routinely fail to parse the confirmation email that actually matters.

Individual hotel apps. Unless you genuinely use that chain constantly, the website is fine.

Anything promising to find you deals. The good version of this is an email alert, not an app.

The thing that beats every app

Screenshots. Your accommodation address, ideally in the local script. Your booking confirmations. Your boarding pass. The map of the route from the airport.

A screenshot works with no data, no signal and no app. It works when the airline's servers are down, which happens. It is the single most reliable travel technology available to you and it costs nothing.

And one step further: write your accommodation address and one phone number on actual paper. If the phone is gone — lost, stolen or simply flat — every app on this page is gone with it.

The bottom line

Offline maps, offline translation, your airline, a flight tracker with alerts, the local ride app, and a password manager. Download everything before you leave rather than on arrival, screenshot the things you cannot afford to lose, and put one address and one phone number on paper. That is a complete travel tech setup and it fits in one folder.
