LTWatch for London Transit is a travel and navigation app that provides real-time information about London Transit buses. The app is exclusively available on iPhone and is developed by Barum Rho. With LTWatch, users can see the current location of buses on a route map and the next arrival times at major stops. The app also provides easy access to full timetables from London Transit website. The bus locations and arrival time predictions are provided by the LTC as available on their website.

The app is useful for those who rely on public transportation in London and want to plan their trips more efficiently. However, it is important to note that the arrival times are not always accurate, so it is recommended to arrive at the stop a few minutes earlier. Additionally, the app is not affiliated with the London Transit Commission.
