Brilliant!
This app is simply fantastic! Not only will it show one the rout one needs to take, it will also tell one how many calories one burns by doing so, and e.g. how many lists of lettuce or grand non-caf skim milled lattes it that.
Apart from having detailed view of the tube and buses, it also shows where one can find the city bikes.
It makes everything simple.
