Pretty good app

Of the apps available for London Transit, this is definitely the best Ive seen. The app is great for its GPS-based time estimates and adjusts to route changes pretty quickly. The only issue with this app is that sometimes its estimated arrival times jump forwards or backwards without warning because the individual buses are speeding up to make up for lost time or held back by traffic. However, you can avoid surprises by keeping the app open and regularly checking your buss progress. Overall, an extremely useful and well-organized app.
