London is huge. Over 9 million people live here. Tourists arrive in the tens of millions every year — around 40 million visits were recorded before the pandemic years, and numbers have climbed back close to that since. Getting around without the right tools on your phone? That's how you waste half a day on the wrong Tube line.
These are the best apps for London travel, broken down by what you actually need them for.
Start here. TfL Go is the official Transport for London app, and it covers the Tube, buses, the Elizabeth line, Overground, and river services. All in one place.
Real-time departures. Live service updates. Step-free route options too. It's free and it works offline for maps once downloaded.
Citymapper is, for many people, better than Google Maps in London. It calculates walking, cycling, bus, and Tube combinations together — and it's almost unnervingly accurate about arrival times.
It also covers e-scooter and bike-hire options. That matters more in London now than it did five years ago.
It still works well for surface-level London navigation. Walking directions around areas like Southwark, Shoreditch, or Notting Hill are reliable. But the Tube complexity is where Citymapper has the edge.
Use both. They complement each other.
Less known, but very useful. London has some genuinely confusing addresses — especially in parks, markets, and large venues. What3Words divides the world into 3m × 3m squares, each with a unique three-word address.
Telling a black cab driver "///limit.verb.tiger" is oddly efficient.
Worth repeating here. In an emergency in a park, large venue, or unfamiliar street, being able to give a precise three-word location to emergency services can matter a lot. The UK's 999 service now accepts What3Words coordinates.
You'll constantly use public Wi-Fi in London. The problem: public networks are open. A VPN routes your connection through encrypted VPN servers before it reaches the internet.
VeePN is one option worth knowing about here. Using VeePN secure VPN, you can avoid data leaks when connecting through an insecure connection. You can also redirect traffic through VPN servers to bypass regional restrictions. A VPN is also useful on secure networks, as it offers anonymity and protects your digital identity. If anything goes wrong health-wise, the NHS App connects UK residents and visitors registered with a GP to medical records and services. For tourists, it's at minimum a useful pointer toward walk-in centres and urgent care.
London runs on events. From free gallery nights in Mayfair to warehouse raves in Hackney. Eventbrite aggregates a huge range, many of them free or cheap.
Filter by date and distance from where you're staying.
Time Out has been covering London since 1968. Their app and site list restaurants, exhibitions, theatre, pop-ups, and hidden gems by neighbourhood.
Their "Love London" section is especially useful for first-timers wanting curated picks rather than algorithm-driven results.
Both are popular digital banks in the UK. Either one lets you spend in London without foreign transaction fees—important if you're visiting from outside the UK. And yes, it's still important to use at least a free VPNwhen connecting to public networks and elsewhere. Digital security is always a plus. Monzo has a coral-colored card that's become something of a London landmark in its own right.
Traveling with others? London expenses add up fast. A show, a meal, a day trip to Windsor. Splitwise tracks shared costs so no one's quietly resenting anyone by day three.
Reservations in London can be surprisingly necessary. Even on a Tuesday. TheFork covers a wide range of restaurants and often has discount deals for booking through the app.
For nights in, or rainy afternoons that turned into evenings. Deliveroo is the dominant food delivery platform in London, with coverage across all boroughs.
Uber Eats also works well, particularly in central areas.
If you're travelling from outside the UK, XE gives you live exchange rates and a clean converter. The pound sterling moves against most major currencies — check before you spend.
Surprisingly useful even in English-speaking London. Menus in Borough Market's international stalls, signs in Chinatown, or just confirming what a British friend meant by "gutted." The camera-based real-time translation is the feature worth knowing.

London rewards preparation. Download these before you land — not on airport Wi-Fi. That way, even if your data connection is slow in the Underground, the essentials are already cached and ready to use.
