London's Tube carries over 5 million journeys a day across 11 Underground lines, the Elizabeth line, DLR, Overground and National Rail. For tourists, knowing which train, which direction, and which exit — all while underground with no signal — is the difference between a smooth trip and a stressful one.
Open CityNav Free → See London transit coverageCityNav pre-loads every London Underground, Elizabeth line, DLR, Overground and rail line so you can plan routes with zero mobile data. Essential for travellers on foreign SIMs where roaming charges apply.
Point your camera and AR arrows guide you from the Tube exit directly to Tower Bridge, Big Ben or Buckingham Palace — no need to rotate a map or guess which direction to walk out of a busy station.
CityNav tells you the cheapest way to pay for each journey. London's daily cap with contactless means you never overpay — the app surfaces the right fare strategy so you don't accidentally buy the wrong ticket.

CityNav is designed specifically for tourists, with offline Tube maps for all 11 Underground lines plus the Elizabeth line, DLR and Overground. Unlike Google Maps, it works without any mobile data — essential for international visitors on foreign SIMs. AR walking directions and an SOS emergency button add extra value Google Maps does not offer.
CityNav works fully offline for all 15 London transit lines including the entire Underground network, Elizabeth line, DLR and Overground. Once loaded, you can plan routes and view station information without any mobile signal — important since much of the Tube runs underground with no data coverage.
You don't — contactless bank cards and Apple Pay/Google Pay now work on every Tube, bus, DLR and Overground service with the same daily and weekly caps as Oyster. CityNav advises on the cheapest fare approach for your journey length so you never overpay.
CityNav covers all 11 London Underground lines (Bakerloo, Central, Circle, District, Elizabeth, Hammersmith & City, Jubilee, Metropolitan, Northern, Piccadilly and Victoria), the Elizabeth line, DLR, London Overground, Southern Rail and Thameslink — 15 lines and 140 key stations in total.
Yes — CityNav has an AR walking mode that overlays directional arrows on your phone's camera view. This is particularly useful in London where emerging from a Tube station in an unfamiliar area can be disorienting. Point the camera, see the arrows, and walk straight to your destination.
The fastest and cheapest way is the Elizabeth line (formerly Crossrail) — it runs directly from Heathrow Terminals 2, 3, 4 and 5 to Paddington, Bond Street, Liverpool Street and beyond. CityNav covers the Elizabeth line offline so you can plan your airport journey before you land.
CityNav covers 28 major cities worldwide with the same offline maps, AR navigation and SOS emergency.
