iTube is an application for planning your journeys throughout london and the greater london (TFL) area.

iTube can take a stop/station name, postcode or address and tell you which transport options you need to use, including tube, bus, tram, DLR, overground and national rail services.

iTube also includes a complete tube map as well as current and upcoming tube status, informing you of possible delays or line closures. The journey planner will avoid closed sections or the line.

The journey planner is available whenever you are online, and recent searches are saved so when you are underground you can remind yourself of them.
Similarly tube status will be updated whenever you have internet, and will be available if you wish to check later with no signal.
