You’re out in London. You don’t know where the night will take you but you know you can’t miss the last train home.

Leave London tells you exactly what the latest time you can leave almost any location in London is and still catch the last train back home. It even takes into account any changes you need to make and the time it will take for you to walk from where you are to the station.

This is the lite version of Leave London, which supports all the same route planning and journey finding as the full version, but lacks the ability to set reminders for when your latest train is or track you to keep your journey updated. It is also ad supported, unlike the full version.

FULL VERSION FEATURES

• Support for range of services including: National Rail, Underground, Overground, Tram and DLR
• Live route data from Transport For London’s (TFL) Journey Planner system; this takes into account weekend timetables, replacement bus services and any other disruptions reported
