See live bus times for London Buses.

IMPORTANT: The purpose of this app is to keep you updated on the latest arrival times for buses based on traffic conditions and other factors, this means that expected times might change based on local conditions while you are waiting. If you don't like to see live bus times, please refer to the timetables at the bus stops instead (I have to point this out as some users have complained that bus times changed while waiting - this is exactly the point of this app - to keep you up to date!).
