Seems like a good idea.  Put all the great buildings of the world into an app that not only tells you about the building, and provide images, but uses GPS to guild you to the buildings.   Nice. ‘Architecture’. the name of the app, will direct you to nearby building of note based on your current location.

The site says its comes with 580 buildings from 165 architects, in 270 cities with over 1000 images.
