Major bus routes
Simple schematic map of the major bus routes. The same as the one they give out at tube stations, but easier to carry. When you ask it to give directions from point to point, the recommendations can be somewhat odd, but its easy to figure out for youself by looking at the map. I had hoped to find a map like this for free (like you can for the tube), but Im glad to have it at 99cents.
Update: doesnt reflect route changes made in August. So not very useful when Im in London now, trying to use it. Dropping from 4 to 2 stars.
