Android mapping app

In preparation for an upcoming trip, I have found an Android mapping app that should make my life a lot easier in some strange cities. TravelDroyd is an app that apparently provides turn-by-turn navigation and a useful general map for many major cities around the world. I only say apparently as Wellington is not one of the cities and so I can't test it before I head off... Also, although the app is free [and comes with Berlin for free], the other maps are paid for.

There is another related app, MapDroyd which contains world-wide maps for free, but without the navigation and a few other features [yes, I have that app also]. Here are a couple of pictures.
