Next time you find yourself wandering around a foreign city, you can check your iPhone to see what interesting architecture may be nearby. Architecture is the first GPS based architectural pocket guide for the iPhone. This application tells you where the most architecturally noteworthy buildings are located worldwide. You can download a free 3 day trial and take it for a test drive.
Architecture, created by Bas Berck, "tells you the story behind the building and the architect, shows two images for each project, website and address, and a detailed map with walking or driving directions. It also presents you with a Google Street View where available. Projects can also be browsed by categories 'cities' or 'architects' with no data connection needed, because all information and pictures are stored offline on the end-user's phone. Architecture contains projects from 165 different architects, in 270 cities worldwide. It has more than 1000 pictures from buildings stored internally."
You can download a free 3 day trial version. The application is USD 3.99 / EUR 2,99. More info available here.
