No one paid for this list. These are the apps people actually use before, during and after a trip — including Wayra, which is ours. We slotted it into its own category, not first place, no rigging the ranking.


How we chose (the honest criteria)

The list runs through three simple filters. One: each app solves a specific problem that comes up in almost every trip. Two: it's available on iOS and Android, in English, without a subscription for the basics. Three: we'd use it even if we weren't writing this list.

The order isn't "best to worst" — it's by phase of the trip: planning, on the road, in a group, afterwards. Some apps span more than one phase; we put them where they earn their keep.


01
Planning · Flights

Skyscanner

Category Flight aggregator
Cost Free
Platforms iOS, Android, web

The most reliable airline aggregator. You search a destination, it shows you every option across every airline, layovers and direct. The features that actually earn their keep: "whole month" (a calendar of the cheapest days) and "anywhere" (you give it your date and origin, it lists the cheapest destinations in the world). The second one surfaces weekends you'd never have thought of.

Good
Worldwide coverage, price alerts, no checkout surprises. The mobile app remembers your filter between searches.
Less good
It redirects you to the airline's site to buy — sometimes the price ticks up in the final step. Cross-check on Google Flights before you close.
Tip
Set a price alert as soon as a route catches your eye. It pings you when the price drops, no need to re-search manually.
02
Planning · Accommodation

Booking.com

Category Hotels and apartments
Cost Free (commission paid by the hotel)
Platforms iOS, Android, web

The de facto global standard for hotels and apartments. The reason: free cancellation on 80% of bookings, which lets you "block" accommodation in a first draft of the plan and swap it when things firm up. Reviews are plentiful (millions per hotel) and reasonably trustworthy if you filter by "travellers like you".

Good
Free cancellation by default. Genius programme (10–15% off from the fourth check-in). Granular filters.
Less good
For short-let apartments, Airbnb and Vrbo have a better catalogue. Booking falls short on whole-flat listings for groups.
Tip
Book early for the free cancellation, but before the trip cross-check Hotels.com and the hotel's own site — sometimes the direct rate is 10–15% lower.
03
Planning · Transport

Rome2Rio

Category Intermodal comparator
Cost Free
Platforms iOS, Android, web

The app that answers "how do I get from A to B?" when A and B are any two cities on Earth. It shows every combination — flight, train, bus, ferry, shared taxi — with price and approximate duration. It's the tool for quickly comparing whether you should take the Eurostar, fly, or drive between, say, London and Paris.

Good
Covers the whole planet, including local bus routes in countries Google Maps doesn't reach. Compares options on a single screen.
Less good
Prices are approximate, not the real-time figures. To book you need to go to the operator's website (Renfe, FlixBus, etc.).
Tip
Most useful in countries with dense transport networks (Europe, Japan, India). In Latin America the coverage is patchier.
04
Planning · Itinerary

Wayra (this one is ours)

Category AI trip planner
Cost Free · Plus €4.99/mo
Platforms Web (every platform)

Wayra builds a full itinerary from a single text prompt. You type "7 days in Japan for 2 people, mid-range budget" and it returns a day-by-day plan with neighbourhoods, real restaurants and a realistic budget. You modify it by chatting, share it with your group via a link (no accounts for them), and the expense splitting is automatic. Honestly, it's what we used to cobble together with TripIt + Splitwise + Notion — now in one place.

Good
No account needed to invite the group. Full plan in 30 seconds. Expense splitting lives inside the plan, not in a separate app. Real hotels and flights (Amadeus).
Less good
It's new (we launched in 2026) and there's no native mobile app yet — only responsive web. If you want something installable, not yet.
Tip
Try one trip free without signing up. wayratrip.io. If you like it, you can save trips forever with a Google sign-in.

The trick with travel apps isn't owning the best one in each category. It's knowing which app belongs in which moment of the trip.


05
On the road · Maps

Google Maps

Category Navigation and reviews
Cost Free
Platforms iOS, Android, web

Non-negotiable. It covers three uses a day on any trip: how to get there on foot or by public transport, which restaurants nearby have decent reviews, what their hours are. The most underused feature: download offline maps before you leave. It carries you through the whole day without mobile data abroad.

Good
Offline maps. Reviews with photos. Up-to-date opening hours. Public-transport directions.
Less good
In some big-city metros (Tokyo, London), its routes aren't optimal — Citymapper beats it there (see next).
Tip
Before you leave the hotel wifi, download the map of the entire city. It works without data for walking and driving directions.
06
On the road · Urban transit

Citymapper

Category Public transport
Cost Free
Platforms iOS, Android, web

For cities with complex metro systems (London, New York, Tokyo, Paris, Berlin, Madrid, Barcelona), Citymapper beats Google Maps on one thing: it tells you which carriage door to stand at so the exit at your transfer is closest. It also tells you when a bike or e-scooter would beat the metro for that specific journey.

Good
Hyper-detailed metro directions. Side-by-side comparison of options (walk, metro, taxi, bike). Strike and closure alerts.
Less good
Only covers a handful of major cities. In smaller cities or towns it just doesn't work — fall back to Google Maps.
Tip
The "rain safe" option calculates the route with the least time outdoors when it's raining. Comes into its own in London and Tokyo.
07
On the road · Language

Google Translate

Category Multilingual translation
Cost Free
Platforms iOS, Android, web

The underrated feature is the live camera: point at a menu in Japanese, Arabic or Cyrillic, and the text translates over the screen in real time. Equally useful for signs, product labels, receipts. Voice translation works reasonably well for short conversations.

Good
133 languages. Camera translation works offline if you download the language first. Saved phrases at hand.
Less good
Slow for long conversations (3–5 seconds per turn). DeepL translates better but covers fewer languages and has no camera.
Tip
Before the trip, download the country's language for offline use. Saves on roaming data and works in the metro or out-of-coverage spots.
08
On the road · Currency

XE Currency

Category Currency converter
Cost Free (optional premium)
Platforms iOS, Android, web

Currency converter with the mid-market rate, refreshed every minute. Useful for sanity-checking whether a menu price in yen or dirham is reasonable. If your bank charges a 2% conversion fee, it helps you do the real all-in maths before paying by card.

Good
Works offline with the last-loaded rate. 180 currencies. Historic chart to understand trends.
Less good
The free version has ads. Premium removes them but doesn't add anything useful for a normal trip.
Tip
If you have Revolut or Wise, those apps already show the rate without a markup. XE only earns its place if you use a traditional bank with a regular debit card.

09
In a group · Expenses

Splitwise

Category Expense splitting
Cost Free · Pro €3/mo
Platforms iOS, Android, web

The historical standard for splitting group expenses. We used it ourselves until we built Wayra. It works well at its single job: each person enters what they paid, the app calculates final balances and tells you who owes whom in the fewest possible transfers. If your only problem is settling up after the trip, Splitwise is perfectly fine.

Good
Impeccable balance algorithm. Multi-currency support. Receipt OCR in the Pro tier. Clean mental model.
Less good
Requires every member of the group to create an account. Doesn't integrate with the trip plan — expenses live in one app, the itinerary in another.
Tip
If your plan already lives somewhere else and you only need to split expenses at the end, Splitwise does the job. If you want plan + expenses in a single tool without your group having to sign up, that's where Wayra adds different value.
10
After · Memory

Polarsteps

Category Travel diary and map
Cost Free · Premium €3/mo
Platforms iOS, Android, web

An app that runs in the background and automatically draws the map of your trip as you travel. You add photos each evening from the camera roll and end up with a travel diary that built itself. The Premium tier prints the trip as a physical book — it's been one of the most successful post-honeymoon gifts of the last decade.

Good
Effortless automatic map. Works offline (syncs when you're back on wifi). Optional physical book, high quality.
Less good
Drains battery in the background (noticeable on long trips). Privacy: by default it shares your location with your network — check the settings.
Tip
Turn on "battery saver" mode in settings. It cuts GPS-logging frequency without any visible loss of precision in the final map.

Honourable mentions

Apps that nearly made the top 10 but were cut for overlap, niche use, or because something else on the list already does the job:

  • TripIt — Itinerary aggregator that pulls from your inbox. Useful if you book everything via Gmail. Wayra covers the plan as a single piece, but if you like the "book, forward to TripIt, done" flow, it still works.
  • Hopper — Predicts flight prices ("wait, it'll drop"). Useful when your dates are flexible. ~70–75% accuracy by their own published numbers.
  • Revolut or Wise — Cards with the interbank rate and no markup. Saves 2–3% on every spend in foreign currency. More of a financial tool than a travel one, but it earns its place the moment you use it.
  • Hostelworld — If you're travelling backpacker-style, still the most complete catalogue of hostels with relevant filters (clean, party, backpackers, couples).
  • AllTrails — Hiking trails with difficulty and reviews. Non-negotiable if you're planning trekking.
  • FlightAware or Flighty — Flight status with push notifications. Tells you about a delay before the airline does.

How to combine them (minimum viable stack)

If you only want to install three before the next trip:

  1. Wayra for the full plan + group expense splitting.
  2. Google Maps with offline maps downloaded for the cities you'll visit.
  3. Skyscanner with price alerts on the routes you care about.

If your trip involves a country with a different language, add Google Translate with the language downloaded for offline. If you'll spend several days in a major city with a complex metro, add Citymapper. The rest of the list is optional, depending on the trip.


Frequently asked

What's the best free app for planning a trip?
Depends what you mean by "plan". For finding flights: Skyscanner. For accommodation: Booking.com. For a complete itinerary (what to do day by day, with neighbourhoods and restaurants): Wayra. For comparing transport between cities: Rome2Rio. No single app does everything well — the trick is combining them.
Is paying for premium worth it on any of these?
Generally not for the occasional traveller. Splitwise Pro (€3/mo) adds receipt OCR and categories. Polarsteps Premium (€3/mo) unlocks the printed book. Citymapper Plus (€4/mo) adds routes with fewer transfers. For people who travel 3+ times a year, Wayra Plus (€4.99/mo) adds unlimited modifications, PDF exports and trips saved forever.
Does Wayra replace Splitwise?
For someone who already has their plan elsewhere and just needs to settle up at the end, no — Splitwise is perfectly fine and specialised. For someone who wants plan + group expenses in a single tool without the group needing to sign up, Wayra adds different value. The two apps often coexist: Splitwise for everyday expenses, Wayra for trips.
Why isn't Airbnb on the list?
Overlap with Booking.com, which also lists whole apartments. If your trip leans heavily on short-let apartments rather than hotels, add Airbnb without question — its catalogue in some regions is better than Booking's. The hotel-vs-apartment choice defines which one you install.
What apps do tourism professionals actually use?
The same ones plus a layer on top: Sabre or Amadeus (the booking systems agencies use), Travelport. For private guides, Allianz Travel or SafetyWing for insurance. And, regrettably, still a lot of Excel.
Are there any European apps worth installing?
Wayra (we launched in 2026 from Madrid). Trainline for booking trains across Europe in a single interface — better than each national operator's site. Omio for combining trains, buses and flights across Europe. Citymapper is also a London startup, even though it now covers cities worldwide.
How do I manage all these apps without filling up my phone?
One folder on the phone ("Travel"), the four mainstays (Wayra, Google Maps, Skyscanner, Booking) on the first screen, language and currency on the second. The ones you only use during the trip (Citymapper, offline Translate) you download on arrival and delete on the way back — saves space without losing utility.
